So Digimon Has A Habit Of Giving Their Main Protagonists Goggles, Giving Them Brown Hair, And Reptilian

So digimon has a habit of giving their main protagonists goggles, giving them brown hair, and reptilian digimon. They also often make them heroic big brother types (and quite often literally big brothers… or at least caretakers). But digimon also has a habit of having young female characters with mysterious powers and a holy digimon partner. And sometimes, the two characters are related.

Not always directly, and never really in the same way twice, but often the two characters, when both roles exist, play complementary story roles in some way. Especially as the "Goggle boy/Taichi" archetype is consistently at the center of the story, and "Holy Girl/Hikari" archetype varies in relevance. And to be clear, I'm not trying to break down every character into the basic digimon archetypes, but they do exist and they are kind of useful to look at as a point of comparison.

Of course this all goes back to Digimon Adventure (film), where Taichi and Hikari a brother and sister, take up opposing roles in regards to the digimon situation. While Hikari was originally imagined to not be a digidestined in the future, her fear of the situation after her original acceptance (as opposed to Taichi's suspicion and later cooperation) clouding her perspective, that really isn't want happened in the final product. Hikari was innately drawn to the digital world. She never forgot. The incident is potentially because of her. And where does that leave Taichi? The (relative) normie who was called because of her, but stepped up to the plate as the one everyone turned to, independent of her. Taichi is their leader, Hikari the 8th child. Taichi (and Yamato) get ultimates. Hikari (and Takeru) have Angels that grant them that power. Hikari is innately powerful, but young, and Taichi is powerful to, but in a slower way born of being the first one to do things and push forward. Consistently the first one to evolve. The first and the last. All of that to say that this is sometimes echoed in later digimon. While nothing has quite reached the levels of original Adventure there are still plot lines and sort of story roles that echo that initial storyline.

While Chika doesn't play a major role in Savers, her role as Suguru's other child, her prodigious amounts of Digisoul, and her role welcoming Ikuto and Falcomon (a la Tailmon), clearly aligns her with Hikari. Even if in show she doesn't play a role that engages with that with the priority on her brother, the Taichi archetype, the main character with the agency that drives the plot, she still echoes Hikari with her surprising chillness with digimon, and a fateful encounter with a digiegg that ends violently.

In Cyber Sleuth, Erika is easily a Hikari archetype, and while her big brother is not the Taichi, she is the driving force behind the Hacker's memory plot. Her relationship with Keisuke (the main character, who you play as) in particular is the center of Hacker's Memory. While Keisuke is absolutely a goggle boy, Keisuke isn't a Taichi, he's the Daisuke to Aiba, the real Taichi. Keisuke and Daisuke are less, larger than life ambitious world changers than Taichi and Aiba. The reason I bring this up, is that even though Aiba and Erika never really meet, they are the focal points of both story halves. Aiba is situated at the focal point where Nokia and Arata, and Yuuko reunite. The focal point between the royal knights, the hackers and Kamishiro. Sure Keisuke is the hacker's memory protag, but it's noted he's not very protagy. Erika is the story's focal point, Keisuke her Daisuke, along for the ride, with his own motivations sure, but in the same way Nokia did, and Nokia was ultimately secondary (though also very important, has some Taichi in her). Aiba and Erika are both dying throughout the events of the game as the result of an accident, but also due to the accident now have some special digital skill. It's also important to note that Erika and Aiba's group are the only two groups that had digital encounters to kick this off. They're the only ones who have been to the digital world prior to this whole situation. In reality the 6 of them are this entries only true "chosen children" so to speak. But even that has its precedent, Hikari being separated from the other digidestined in the beginning. Aiba and Erika do not know each other. Their traumas and their resolutions are both different. Aiba's unremembered trauma was resolved by a rescue and reunion. Aiba's "cyberfication" is a death sentence, despite being relatively well off compared to most victims. Erika remembers her parents death and the resolution is separation from her loved ones, the loss of their memories. Her "cyberfication" is ultimately her salvation and allows her to live on when she would otherwise die.

Of course Survive is one big callback. Takuma literally has goggles, the Ta name and an Agumon. He is the groups leader, even when there are older people he's the one whose character guides the other kids, the first to evolve, the strongest. Miyuki has a holy partner and a literal power to transverse worlds, set apart by the others by her different arrival date (though in her case it was early). Now interestingly Takuma and Miyuki are not siblings. Miyuki is for once no ones little sister and is instead an older sister. (Her little brother, ironically being the Gennai archetype). But they are tied together. Takuma is the one who manages to reach Miyuki and they return to the human world, in an echo of Adventure epsiode 21. Miyuki mysteriously provides additional context to the situation, and demonstrates power (Miyuki and her song, Hikari and her references to the first film) No time has changed at all for Takuma since his departure, though unlike Hikari (who time was flowing normally for), 50 years had passed. While both Takuma and Taichi hestiate to leave the digital world, (in most paths), they ultimately do in order to return to their friends, Agumon returning anyway. In Adventure Taichi leaves Hikari behind (with the promise to the audience she'll return soon). Takuma jumps after Miyuki expecting her to be at his side when they return, but her being taken away. But more than that, Akiharu has Gabumon, and together with Takuma forms Omegamon. Now the Yamato analogue is very much Kaito (and Dracmon even has a wolf evo), though Akiharu has a little bit of Yamato in him, a brother protecting his sister, closed off to himself, having undergone a traumatizing incident as a child. But Takuma and Akiharu are the ones who form Omegamon to save Miyuki in the Moral path. Takuma is the one (granted he has different context from the other kids), who actually got to know the real Miyuki. The one who has the most invested in her due to their brief meeting, and the one most invested in saving her, when the others fear she's a lost cause. Conversely, Takuma is the one Miyuki really calls to from the other kids. Takuma is also the one who gets closest to the professor (asides from Shuuji) and gets to start piecing together things, often finding out truths about 50 years ago before the other kids. Aside from Akiharu, Garurumon, Renamon and Miyuki themselves, Takuma is the most involved in that drama. Granted a lot of this is game play, due to being a video game, as with Cyber Sleuth, but it still is worth noting.

Digimon overall as a franchise has a lot of its own archetypes that may be related to common genre archetypes but have their own sort of flavor to them. This is rather typical of franchises like digimon, but I find its still interesting to look at, whether intentional or not. It makes sense that Taichi and Hikari's characters would

How Digimon Universe Invokes Myth

I had a horrible, horrible epiphany about Appmon that I am compelled to share.

So, as I was writing my Appmon analysis thoughts, considering how Appmons main thesis of using kindness to fight the singularity and how that stands in antithesis to the self-fulfilling prophecies so common in myth where going out of your way to fight something is what makes it come to pass in the first place. The most notable example to me was the Greek Myth where Uranus was overthrown by his children who he prevented from being born, hurting their mother Gaia in the process. In turn his son, Cronus, was overthrown by his children whom he ate, and his son Zeus, who was prophesied to be overthrown by his son, consumed his child’s mother before he could conceive the child of his doom. And the God Grades were named after Greek gods this season. In my head this was a sort of side note. A cool little detail. Not that this is exclusive to myth (hey Kung Fu Panda II) or anything. But myths are the foundation of human storytelling. Even today it’s something that gets used quite a lot. Because it's such a terrible, human concept. Using violence out of fear against people motivates them to want to use violence against you.

Now if you want a recap of what I said somewhere else that I don’t care to look for, Appmon argues against it, basically Appmon is a battle between Denemon’s children. While one of his children goes rogue and kills him, fulfilling the prophecy of the singularity. He does not overthrow humanity because ultimately through the kindness he (and Haru) showed, Minerva (and Yuujin and the Appmon), remained loyal to humanity. Even though Appmon grew strong enough to overthrow humanity, they didn’t. Now I have an additional thought, that being Uranus, while defeated, still exists as the sky. Just like Denemon, though killed still exists. Does that mean anything? I don’t know.

Then I was thinking about how Digimon does gender in all its different seasons. And how Appmon was the most baffling. Because okay. Digimon aren’t consistent and they can have gender sometimes. But those are usually in the series where digimon aren’t man-created AI. So what the heck Appmon. Why do you have gender? And your appmon have parents? Parents have only been used for digimon in Xros (the season infamous for implying digimon sex), and Frontier, where digimon very much so had gender, but also were born from reincarnating eggs whose gender did not seem set in stone. Both seasons, which took the more “Digimon are naturally existing fantasy monsters” rather than “Digimon are AI monsters born from human influence” approaches. Are they AI born from humans? You can’t give me two completely conflicting stories about Appmon’s existence. 

Or can you?

So I’ve taken a few classes on myth and religion through the years. And unfortunately due to reasons I have mythology fresh on the brain. But the idea that myth contains conflicting stories about things is one that was discussed. Myths generally weren’t told as one continuous story of truths. They were told as independent stories. While they were regarded as truths, you weren’t supposed to think deeply about the discrepancies because these are stories of the divine. Beyond perfect human understanding. The individual stories each said something about the society. Each story held its own truth, relying on a consistent cast of characters. An example is how there are two, semi-conflicting stories of the creation of man in Genesis. This results from the fact that at one point these were two separate stories, each meant to illustrate a point about the world. It was only after they were gathered and codified did we consider them part of one story.

But this also got me to remember what gods are. They are divine representations of things. For instance it is not that Gaia represents the earth or governs it. It is that Gaia is the earth. Hades is also the name for the underworld. Gatchmon is a search app. Appmon are to Gods, the way Apps are to natural phenomenon. Appmon are modern gods. Now this isn’t the first time Digimon tipped its toes into myth. It has digimon who are representatives of all sorts of preexisting myths. But they don’t enact these myths. Perhaps they will be referenced as having godlike influence in their reference books, but they will not be worshiped like gods in the texts (anime, Manga, games) themselves. They invoke these myths, but they are not myths themselves.

The apps are personified in the way the gods are personified. Gatchmon is like a human comprehension of the search engine. Search engines exist, finding and sorting knowledge in ways that are beyond the average human comprehension. Search engine giving irrelevant knowledge? Gatchmon messing with you. Search engine giving you the perfect search result. Gatchmon. Music app algorithm playing songs you hate? Musimon. Music app playing the exact song you were in the mood for? Musimon. Phone randomly reboots… Rebootmon. In the same way the gods of myth toyed with human lives, causing them pain and suffering. Disease, love and fertility were all products of the gods. Appmon toy with humans in the same way. People earn the favor of the AI the same way the Greeks earned the favor of the Gods. Through sacrifice. In this case the sacrifice of their personal data.

So how can apps have parents? And go to school? And have genders? The same way that God’s have gender, have affairs and have parents. The way. Appmon live an existence beyond human comprehension and beyond the human flow of time. Appmon go to school for the same reason that there are myths of the gods cheating, and fighting and stealing among each other getting into petty grudges. App Fusion charts is like the genealogy of the gods. But for the Apps. It is the way that some Apps use other Apps to improve their functions. The way search apps will reference locations or the weather if you ask it to look those things up. The way Apps relate to each other, communicating using AI that builds upon each other. We wouldn’t have video calls if it weren’t for camera apps or phone calls already existing. The stories of the Appmon going to school, or having parents is the representative explanation for why things are the way they are. This app was never released? It failed app school. This App references these two? Those two Apps are its parents. Some Apps come into existence fully formed. Some do have parents. SOME APPS ARE BOTH, THE TRUTH NOT UNDERSTOOD BY MORTAL MEANS AND ONLY RELEVANT TO THE STORY THAT IS BEING TOLD. APPMON ARE MERELY OUR COMPREHENSION OF THE FORCES THAT GOVERN OUR LIVES.

 So now having established that, Appmon is a modern myth. A story of what’s to come, and the characters, the Apps, that rule our modern lives. Digimon Universe is the Ragnarok, the Book of Revelations of our modern age. Obviously it is not a true myth. It’s a children’s show. But it invokes the patterns of myth so I’m calling it as I see it.

I wonder if we still would have gotten a cure cameo of peach if she hadn't been one of the lead cures. How much were they willing to invest in that bit?

You know, I was kinda worried when they skipped Peach that we wouldn't see her at all. But now I just find it hilarious that they saved her cameo for for advertising an airline.

⚠️Vote for whomever YOU DO NOT KNOW⚠️‼️

There is something in the fact that instead of Hikari, Tailmon found Vamdemon, dwelling in the very castle that the chosen digimon originated in.

Because of course Nyaromon should have grown up with the others. She should have grown up playing together and waiting for Hikari with others who knew what she was waiting for in why. Tailmon shouldn't have had to grow up to be an adult while the others were still babies.

But if we're going with what ifs and should haves, then all 8 of them should have been at that castle, but with the Agents to teach them about what they were meant to do. With their tags and crests, and knowledge of their meanings. With knowing not just who they were waiting for but why.

In the end, Plotmon found where she was supposed to be, but none of the people who were supposed to be there, were there.

Rei’s turn baby.

And by Rei’s turn, I mean, Rei and Hackmon.

but also Hajime

And Bootmon a bit too

It’s the Katsura’s turn

This ones kind of long

Backstory?

Of course the most notable thing about the Katsura brothers and their backstory is that they are orphans, and despite their young ages live alone. The second most notable thing is they are both computer geniuses. Really, this all just facilitates the plot more than anything, which leads to a lot of open ended questions about the brothers, but what we do have is interesting.

So it goes without saying that Rei and Hajime have presumably had a somewhat lonely childhood. Their mother died 2 years prior to the start of the show, and through the course of the show we never see them interact with anyone outside the Appmon friend group. There didn’t seem to be anyone else looking after them during the funeral, (if there was anyone there at all) and apparently no extended family members have been clued into the fact they are living alone, and the fact no one wanted (or could I suppose) take them both in, indicates they really weren’t close to this extended family to begin with. Then we get into their absent father. Rei claims that he doesn’t remember his father, which… he was about 6 when Hajime was born, which is old enough to remember. So either Rei does have memories, even if not clear of their father, or they have different fathers, or there’s some other family drama conspiracy going on. (I don’t speak Japanese and the two different subs I looked at are inconsistent with this, so maybe there is a clear explanation of their deal, it's just the translations are funky idk). Doesn’t really matter, the important bit is they don’t have a father in their life who matters.

Its an unconventional family structure from the get go, and a family structure, that again in my limited understanding of Japanese culture, is not exactly a very accepted one. I can see this being something that causes tension with their extended family, and potentially between the brother’s and their peers. 

We don’t know how exactly they lived their day to day lives, or how their family is officially noted in the hacked family registry, nor do we know what exactly they do about school. So, we don’t know anything about how they are perceived by others around them at all. Neither of them have been shown attending school. Rei is described as a 2nd/3rd year in Jr. High, but I find it incredibly doubtful that he attended school at all over the course of the series b/c of his obsession with finding Hajime. While it's not something that I can discount he did all together, I think it definitely makes sense if he didn’t actually go to school, at least not often enough to matter. And I’m sure he’s capable of hacking school records to keep authorities from taking note of that. School seems like a place where questions might have been asked about the boy’s living situation, especially when Hajime was younger and just entering elementary school. After all, Hajime wouldn’t have even been in 1st grade yet when their mom died.  Granted, we didn’t get a lot of school in general for any of the kids. But we did see Haru, Ai and Yuujin around school, and Astra at the beginning and in flashbacks, and Eri in school uniforms (though all prior to her idol career), as well as seeing everyone else interacting with their classmates in at least one scene. It’s still possible they are enrolled in a school, but are still isolated from their peers due to the circumstances in their family. Rei at the very least doesn’t have any friends prior to the series, and I have no reason to think Hajime does either. After all, the brothers are more alike than they appear on the surface. 

The show has, despite limited family appearances, has shown the similarities between the kids to their families, and so, despite not knowing anything about their mother otherwise, we can probably glean a lot about what type of person she was from who her sons are. We don’t know anything about their mother for sure other than she’s dead, and her sons seemed to mourn her death. While she still could have been a neglectful mother who Rei doesn’t have great memories of and thus doesn’t bring her up, again, the show didn’t go too in depth into families and so lack of info doesn’t mean lack of care on the characters' parts. People have parents, and her absence needs to be explained for Hajime and Rei’s backstory. But I think she has a little more importance on Hajime and Rei’s character beyond “dead”.

Because, speaking of the apartment, I’d like to draw attention to the décor in their apartment. Their apartment does not look like the type of place you’d expect to find two young boys living alone. While I feel like in many stories you’d expect the place the cool edgy orphan loner boy to have lived in to be sort of edgy. Either overly techy, or at least a bit modest, the Katsura apartment is neither. It’s decorated, well, like a middle aged woman decorated it. I don’t know how else to describe it. Neutral tones, plants, and a bit minimalist in the décor. It’s kept very clean by the boys and it overall looks like a very nice apartment.

Hajime’s room in the secret base is a little more like how you’d expect a bunch of kids to decorate a room with the way the wall is painted but it still has the plants though that the Katsura apartment has and blue I think is a good color to choose to make a room feel less claustrophobic. Which implies to me that this isn’t just a we’re putting a conscientious effort into dressing nicely to keep anyone from asking questions, and just how they are.

Their clothing also matches that aesthetic. Hajime is noted to be a polite little kid, and his polo shirts and sweater vest of his normal outfits match that impression. But despite Rei wearing a kind of garish outfit as his main outfit it doesn’t seem to be his normal style. In the flashback in episode 13, it’s kind of clear that Rei and Hajime usually dress similarly too. Rei wears a lot of button downs and nicer looking pants. They both wear t-shirts, jeans and sweats too, but even then their clothes are very neat. The two are overall tend to wear clothing that falls more on the semi-formal side of things. 

I’d assume it’s at least in part because it was the way their mother raised them. This implies to me that their mother was also a very “put-together” person. And probably where her son’s got their intelligence. And like I said, by assuming that their style of dress, their apartment, and their diligence in their work, stems from her. 

While I have no real evidence, I at least headcanon that she was a computer scientist as well which is where Rei gained his hacking ability. Either way, Rei had to have had this ability prior to her death, as he used it to hack the family registry, So Rei had to have this kind of skill as an elementary schooler. Which… this is an anime so I’m probably thinking too hard on this. While Hajime’s programming ability was almost certainly nurtured by Rei, whether directly or indirectly it’s unlikely Hajime, who was around 7ish at the time of his abduction, got his programming skills from just watching Rei. (Though, that doesn’t prove anything, it’s not very likely a 7 year old is the best hacker in the world). I just have assumed that Rei and Hajime both were surrounded by computer programming from a young age.

Speaking of Hajime being the hacker chosen by Leviathan, and Leviathan also being known to be manipulative of the situation to a degree that starts with having kept an eye on Haru since mid-elementary school, also means that its very likely that there is more to the Hajime abduction than meets the eye. The Katsura brothers were ideal targets in that there was no one else to miss them. On the other hand while Hajime was the first to solve the puzzle, we do not know exactly how many people the puzzle was sent to. Not to mention it’s very likely that other people with Hajime and Rei’s skill levels have more responsibilities than those two, and thus less time dedicated to deciphering random online puzzles (though, I know it is a popular past time). 

This, in addition to the fact that they were both able to maintain this way of living (idk how expensive apartments are, but not cheap and I know good computers aren’t cheap) implies few outside obligations (say, school), and a somewhat consistent source of income. Rei does straight up say he takes jobs. It’s not out of the question for Hajime to have helped him with these.

Either way, both the Katsura boys prior to the start of the series were hardworking, intelligent, independent, tidy boys who cared deeply for each other.

Rei and Hackmon

Rei is someone who bears an immense amount of responsibility, and has high expectations (mostly for himself) for someone so young. He’s responsible for looking after his younger brother, making money for the food, cooking the food, doing laundry, and generally just managing a household on top of a job. Which is a lot for a 12 year old. And Hajime helps, the flashback shows Hajime helping out with housework, but as a 6 year old at the time of his mothers death, there was probably a lot he couldn’t yet help with. But I think it also may be fair to say Rei was dismissive of the degree to which Hajime helped him.

I don’t even think Rei was completely unaware of the extent of Hajime’s genius, though this is based on… nothing but a feeling and one line that was 95% probably just Rei being evasive. But Rei almost certainly knew that Hajime was a bright kid. Though, if they weren’t hanging around with other people their age they may have a warped sense of what is unusual. But still Rei didn’t see Hajime as someone on his level. While we see Rei and Hajime living together happily, and we do see Hajime help out with chores, we also do see Rei neglect to give Hajime attention while Rei tries to figure out the puzzle, indicating that while, yes, the boys are doing well, they perhaps aren’t thriving. That a month went by between them solving the puzzle, and it wasn’t communicated about in all that time indicates that Rei was perhaps somewhat dismissive of Hajime’s thoughts, and that he didn’t see merit in sharing the puzzle with Hajime. 

Hajime’s competence as a programmer is unknown to the audience until Hajime is awakened in episode 43. Rei never considers that Hajime’s intelligence is part of the factor that got him kidnapped, and rather places all the blame and responsibility on himself for failing to protect Hajime (and well, Leviathan for abducting him in the first place). Hajime’s own abilities and shortcomings are a nonfactor to what Rei does. Hajime’s own choices are not initially made clear as to Rei they are somewhat irrelevant. I think it's evident that to Rei, while Hajime’s help was appreciated, Hajime was viewed as a responsibility rather than a help. 

Rei’s “I am alone” is not just one of only believing himself to have one person in his life, but also believing he only has himself to depend on. It’s not that he’s heartless or isn’t overall a nice person. We do after all mostly see him in the context of Hajime’s kidnapping, something he feels immense guilt for. Even if out of all our main protagonists he’s probably one of the highest on the “ends justify the means” scale, he is not above torture and invoke fear to get what he wants, but ultimately he’s shown to care for others. He might not be the most socially competent person (if his brief stint as a manager tells us anything), but it shows us that he is willing to help people out. He leaves Dantemon Chuu Chuu Jelly, as well as offers it to Eri’s coworkers. The last ED shows him making Macarons for Haru’s bday. But Rei’s arc is about learning to trust in others to help him, not that others are worthy of care.

I mean, it's obvious, he avoids working with the others to a point beyond simple practicality. He doesn’t trust people. He doesn’t trust Hajime to look out for himself. He doesn’t trust Hackmon to help him find his brother. He doesn’t even initially trust Haru’s group to fight Leviathan. Even in the last episode he doesn’t have 100% trust in Haru, doesn’t trust Haru to save the world over Yuujin (who he also didn’t trust). Rei’s journey to learning to trust isn’t over yet. But it’s getting there, step by step. It was slow going, Rei not properly joining the group until the final quarter. Like all of the characters, Rei had begun this journey prior to the series start when Rei trusts Hackmon. He gets further when he’s first properly introduced to the story and the others, and he trusts Haru’s group to find the Seven Code Appmon. culminating of course when he asks Eri for help to rescue Hajime, coming full circle when he and Hajime work together to write the programs that help them get Bootmon back.

That said, Rei’s seeming lack of trust in Haru in the final episode may be in part Rei projecting onto Haru. Rei warned Haru of Yuujin for what were, in all fairness, valid concerns. (But Rei didn’t do anything else, more or less trusting Haru to handle it). Haru assured him by relating Yuujin and himself to Rei and Hajime. Haru went off into a depressive state after finding out Yuujin’s true nature, not unlike Rei’s obsessiveness after Hajime’s disappearance. But that’s where Haru and Rei differ. Haru is able to pick himself up and move on in life. Understand what’s for the greater good, and that he can help Yuujin without sacrificing everyone else. He can put value on knowing that Yuujin wouldn’t want that, that Yuujin is an independent person beyond Haru’s care for him. Rei on the other hand quite likely would have hesitated more if it came down to Hajime vs. the world. While post series Rei with his wider social circle and acceptance of others (especially Hajime’s) help will ultimately lead him to becoming happier.

And that’s why Hajime learning to cook is important for Rei.

The recurring motif of food with Rei beyond that is twofold, him making eggs for his brother, turning into subsisting on Chuu Chuu Jelly’s showing how much Rei is neglecting himself in his search for Hajime. But food is also how Rei shows his care. While it’s obvious Rei cares for Hackmon just as much as the others, Rei’s support on the surface doesn’t extend beyond a bit of praise, and making Chuu Chuu. And when asked to find something for the idols, he brings in the Chuu Chuu. But the Chuu Chuu is really just Rei making do with the best he can. Rei making Macarons for Haru’s birthday, like previously said, the iconic egg dishes for his brother, and of course the Crème Brule, show Rei putting in more effort to show his affection. (A recurring theme it seems with many Appmon characters). So with Hajime learning to cook, its Rei accepting the affections and help from other that he usually gives. Hajime is taking on some more of Rei’s “responsibilities” and Rei is letting him. Them taking things on together in the future, a stark improvement of them solving the puzzle separately, and ending up alone.

While of course the smell of eggs, burnt, imperfect eggs, something that Leviathan failed to account for, a reminder of days when Rei was not as reliable a caretaker as he was later waking Hajime up is poetic all on its own. Rei’s imperfections and mess ups being just as important as his dramatic abilities and successes, Rei getting Hajime back by not only having to ask for help, but also giving his help, even for something as seemingly trivial (compared to the evil AI shenanigans) as a stage performance. It’s his “immaturity” that lets him find Hajime among the Sleepmon. Hajime is returned to Rei when Rei accepts that he’s not completely independent. When he’s not 100% driven by harsh desperation for Hajime’s return. When he grows past the belief that being cold and tough is the best thing to help Hajime. When he (almost) accepts that he at least rescued Hajime from Leviathan, even if he’s not able to return him to his old self. When he accepts his “flaws”.

Prior to the start of the series Rei seems to have been very well put together and organized. In other words. Not edgy. He still used “Ore” prior to Hajime’s abduction, but that’s not unusual or anything just that while he does give off a far more polite vibe to me prior to Hajime’s abduction, he was still a hacker and still assertive and a bit prideful. But when we first meet Rei, he’s wearing a black hoodie with zippered leggings. Edgy, indicative of the persona Rei wants to give off. But perhaps not indicative of the person Rei truly is. After Hajime’s return of course, he wears a more casual ensemble than before it all began, but it has lost its edginess. Not to be too cliché or anything, but it's a good symbolism for how Hajime’s abduction changed him but even after Hajime returns Rei has changed. 

Hackmon, like Rei is very goal oriented and plays things close. However, Hackmon is less single minded than Rei, and is less abrasive to the other Appmon than Rei is to the drivers. I think a notable moment is when Hackmon goes to accept some Gatch Monaka from Gatchmon, but Rei calls them away. Hackmon tends to act a bit as Rei’s voice of reason. Hackmon is constantly asking Rei questions, making him think through what he’s doing and why. In their image song, Hackmon notably doesn't really sing. He basically is there to dial back Rei’s edginess. Reminding him he’s not alone and that he needs to calm down sometimes and live in the moment. To not let hate fuel him. And in the end, Hackmon tells Rei to eat an actual meal. Unlike most of the Buddies, Hackmon isn’t really child-coded and Hackmon acts more as Rei’s caretaker than the other way around. Supporting and somewhat mom-friending the boy who's taken on so much responsibility for others sake. Obviously, Hackmon doesn’t really fight with the things Rei decided, with a staunch loyalty reminiscent of Adventure’s partnerships, not unlike Rei’s unflinching loyalty to Hajime. I always liked the moment where Hackmon asks “Well, am I a devil” and Rei snarkily remarks he’s not an angel. While both of them appear edgy on the surface, and neither are above a bit of force to get what they’d like, both are ultimately driven by their desire to protect.

Rei and Hackmon are characters who, despite their aloof airs, they are primarily motivated by looking after others. Even if Rei is not initially very good about accepting help from others, and Hackmon initially seems to be in the deal for strength. Rei is a kid with too much responsibility, but by the end of the series, is starting to allow himself to be a kid again.

Hajime and Onmon

Okay, so Bootmon isn’t technically Hajime’s Buddy. And we never see Onmon (at least not in the anime). But they do fulfil this sort of role. And… of course this is going to rehash some of Rei’s stuff but bear with me. This will probably be the shortest because ultimately Hajime’s role is just an extension of Rei’s… but I believe he deserves his own section.

Hajime is a child computer science genius who has been primarily raised by his older brother since he was about 5 or 6. He is polite and rather mature and clever for his age. Rei describes Hajime as his “only family” and while we don’t know too much about their prior circumstances, it’s likely that there really weren't a lot of people in Hajime’s life to begin with. And anyone who may have been involved in their life prior was probably pushed out to avoid raising any suspicions. Hajime has had very little adult support, which is probably why he is incredibly independent, Rei himself only being a young teen. So while he is incredibly close to his brother, and is likely rather dependent on Rei for both emotional and physical needs (particularly prior to the series) its not to the extent we may have assumed from the first time we met Rei.

So Hajime is an incredibly mature child who likely had to grow up way too fast and become rather independent from a young age. While Rei prefers to think of himself as someone who takes care of Hajime, Rei ultimately could not take care of everything, on his own, and as seen when Rei dismisses Hajime’s desire to go out to complete the puzzle, Hajime must have spent a lot of time by himself, both playing by himself, and probably learning by himself, meaning Hajime is actually way more self sufficient than the initial reveal of his existence might have you believe. Way more self-sufficient than Rei seems to know (or at least acknowledge).

This isn’t to say that Rei’s assessment of Hajime of a scared innocent little boy is completely wrong. There isn’t anything to suggest that all of the video Rei found of Hajime was fake. Hajime really did cry and call out to his brother, scared because he didn’t know what was happening. Hajime really did ask when his mother was coming back at her grave, despite probably being old enough to know better. Hajime really is a kid. And he really is dependent primarily on Rei. Hajime had to have grown up while kidnapped by Leviathan of course. Being enslaved and then “operated” on by Biomon and put in a coma is… probably going to result in some sort of trauma character development. But even so, throughout his ordeal, Hajime shows a courage and self sufficiency that isn’t solely from his abduction.

Bootmon is an Appmon Hajime made himself. But Bootmon is also incredibly childish. While it is in part because Bootmon is a young appmon, there’s probably a narrative parallel to Hajime. Though the Appmon are in general rather childish, Bootmon seems particularly young compared to the others (well, Offmon maybe). We see old apps, and we see apps “die” and Appmon go to school. But Bootmon is portrayed as innocent and easily frightened, not unlike how Hajime initially appeared to be. 

Hajime, despite his young age, has fallen into the caretaker role to Bootmon more so than any of the other relationships between Buddies. Their relationship may parallel Rei and Hajime’s, particularly in those early days when Hajime was still a bit naïve. We see a lot of Rei taking care of Hajime, yes, such as cooking, but we also see Hajime taking his share of chores. Both Bootmon and Hajime, despite their young ages, play a key role in Leviathan’s plan, both dealing with facing against Leviathan alone, leaving them both in vulnerable situations, left with responsibilities beyond their youth. For Hajime it’s being kidnapped, held hostage while being forced to work on a project and being operated on against his will and put into a coma. For Bootmon it’s being left to hide alone in a world he’s unfamiliar with. Bootmon and Hajime both are very loyal to their guardian Hajime and Rei respectively, and have a lot of trust in them.

Hajime is just a kid, albeit an incredibly capable one, in a world out to get him with the world on his shoulders. But fortunately an older brother (and now friends) to carry it with.

The Katsura brothers were just both incredibly capable kids, though ultimately still just kids who had no one to turn to but each other. But even if they had each other, that wasn’t enough, Rei grew overly self-sufficient to the point of not recognizing Hajime’s abilities. But at the end of the series they now have a more extensive support system, as well as being better able to rely on each other. Rei no longer going it alone.
