Thank you to @akaza-s-bitch, Maddy for proofreading this giant mess of headcanons.

Vampire!Michael Kaiser 

Once upon a time, Michael was held captive but was given the option of becoming a vampire. He took the offer because there was nothing that would’ve held him back. He wanted to be powerful instead of being weak. However, he does despise being ordered around. 

There was a period of time when he and Isagi hunted together, which was when they were freshly turned into vampires by the same person. Both came to an agreement to eliminate their creator for different reasons. Their creator wouldn’t have expected him to backstab them because he was loyal and respectful, unlike Isagi. 

“I am my own master.” 

He does enjoy being a monster because no one can order him around. He feels powerful and wouldn’t give up this sense of superiority for anything in the world. He is immortal with the exception of supernatural hunter weapons and herbs. He isn’t immune to those by default. He can build up a tolerance to them but they could still kill him. 

Michael is terrifyingly good at luring anyone with his charms and looks alone. He is also the type to play with his food (humans) because he likes to work for it. He likes his prey being terrified because it just makes the reward that much greater and sweeter. To him, the blood of his prey tastes much better when they are terrified. He is very sadistic about it. 

He would roleplay different sorts of people for entertainment. He would sometimes use his victim's identities as an alias. 

He has terrifyingly good senses and purposely acts like a fool. He will think of it as a sort of intense game of cat and mouse. He is also responsible for the deaths of many talented hunters.  

He is one of the scariest vampires to get interested in you. He is a very persistent individual. He wouldn’t give up on trying to make you fall in love with him. 

He also seems to be the type to be into the vampire x hunter romance trope because a hunter knows how to deal with his kind and annihilate him. Kaiser likes living on the edge, it brings a sense of entertainment to his otherwise boring life. It keeps him on his toes and he loves it. And yes he would think it's a love confession if you tried to take his head when you tried to get on his level of seduction. 

When you are in a relationship with him, he would purposely drag his fangs against your skin, preferably your wrist and neck, and other sensitive places in order to watch in amusement when goosebumps appear. He loves seeing you shiver at the sensations that he caused you. 

He can get very handsy and seems to always need to have some sort of connection with you. How else could he protect you from the other creatures walking around in disguise? 

He can be very possessive of and clingy towards his lover. 

He does have the secret wish of finding his match, who would love and join in on his shenanigans. He wants a partner who would get bored just as easily as him to be able to constantly find different ways of entertainment. Someone who would accept and love him for who he is, including his savage self. Someone who will keep him on his toes and can keep up with him. The possibilities of his significant other: his match could be a human, a vampire or a different species. 

Vampire!Yoichi Isagi

Yoichi was held captive and his transformation was most likely a case of being at the wrong place at the wrong time. He was given the option to turn into a vampire, however, it was merely the illusion of having an option. Ultimately, he was turned into a vampire against his will. 

He hated himself and would starve himself very often. He would have died multiple times if he hadn’t been forced to feed. These events caused him to have pure hatred toward his sire, his creator. This was also the case for the sire, who’d expected Isagi to be nothing more than a coward before them in submission.

Instead, Yoichi became his creator’s demise. He annihilated his creator and it was a bloody mess. It also fed into his reputation among other vampires from the older class to be terrified, but also led them to be intrigued by how this fresh vampire had so viciously committed the act of killing his creator. He devoured his creator, causing him to be stronger than he was before. 

There was a long period of time during which he was completely savage and not didn’t care who he ended up pissing off. Kaiser and he hunted together during their time as newbies. Terrifyingly enough, they balanced each other out perfectly. Eventually, though, they separated from each other. 

He caused himself to become a bounty on his head because he had rapidly climbed up the food chain, purely by accident. It wasn’t intentional on his part. He became worth a lot of money within both the hunter and vampire realms because he had killed humans and vampires alike without any sort of mercy. However, there was a visible behavioral pattern whenever he killed: it wasn’t impulsive killings of random strangers, more like calculated attacks.

He eventually does reflect on the past and has some regrets about when he was in his savage phase. He strives to be better now.

He is also the first one to befriend a hunter, who was a vampire as well: Rin Itoshi. It was an unusual friendship, but they remained close. At the time, Isagi majorly was his informant because he was everywhere and had more connections than the hunter. 

He did develop white highlights through his dark blue hair due to trauma when he was a newbie, ever since then it's been growing like that. He was starting to like the look of his hair. 

It took a long time for Isagi to accept himself as a vampire. It’s part of the reason why Rin and he got along with each other. Isagi could empathize with Rin since it wasn’t his choice to be like this either. 

He often hunts in the woods for food but also makes money because he was the son of a hunter. Nothing goes to waste. It is also how he met Seishiro Nagi. 

He would often visit the company of his friend Reo, who runs a blood bank for the supernatural who need blood to survive. He pays each blood donor, and Isagi just needs to pay a fee to get blood bags. 

Yoichi took a page from Kaiser's book to roleplay as a human out of boredom. It's most likely how he found his lover, through work or the place he frequented most of the time. 

If you are human, he will keep the facade up as long as possible. It’s either he comes out to you when he is ready to further down the line or when he is forced to reveal his vampire side to you in order to keep you safe. 

He is the type to fall in love hard and get protective over you regardless of whether you can take care of yourself or not. You could be a vampire, a demon, or any different species. 

It's worse if you are human though because the constant worry hangs over his head. He has made a lot of enemies throughout his time as a vampire and doesn’t want anything to happen to you. 

He would fall in love with you even more if you saw his vampire self and accepted him for who he is.

If you are a human around a supernatural creature, he may get territorial and overprotective because he knows they are most likely looking for food.

Overall, he is literally like your guard dog, especially if you are a human in a supernatural environment. 

Vampire!Reo Mikage 

Reo comes from a pure bloodline of royal vampires that have lived for many centuries and generations. He is considered a prince to the present day within the vampire realm. He comes from old money and has many estates under his name. He moves around a lot and sometimes uses a fake name. If he ever returns to the same area he has lived in before, he will lie on the spot claiming to be a descendant of the Mikage. 

He has been taught to have good control over his bloodlust. It lessens his chances of losing control and exposing himself. He learns how to blend in with the humans, lowering his chances even further in order to not be on the hunters’ radar. 

In the beginning, he eventually only left the estate because he couldn’t bear with it anymore: He felt suffocated by his family, especially his parents. During this time, he kept wandering from one place to another and eventually met Seishiro Nagi, a farmer. Nagi let him follow him around as long as Reo helped him with his daily chores. Nagi wasn’t treating him like royalty, so he was a fascinating human to Reo, an enigma.

By pure accident, Nagi became his first creation. Nagi was immune to royal vampire compulsion and eventually became stronger than Reo himself. He was intrigued but also scared of what Nagi was capable of. 

They did have a rough patch where Nagi did cut ties with Reo for a bit, but they eventually reunited with mutual friends. The separation did them well. It is now very rare to see the duo being separated, and even if they are, the other is always close by. 

Reo founded a business: a blood bank, which Nagi was the co-owner of. Nagi was the one who came up with the concept and Reo brought it to life. It was a blood bank where supernatural creatures could buy blood bags with no questions asked, as long as they paid the fee. It was a successful business, the company eventually branched out to sell other species' blood in exchange for money. 

It was successful because Reo paid good money for humans to come and donate a bag of blood, even more so if they were a different species. The company staff was mixed, there were both supernatural creatures and humans. Reo paid his workers very well, it was the best place to work at because of the work-life balance it provided in combination with the high salary. 

He would donate human blood to various hospitals to avoid suspicion from his human workers and outsiders. 

He does have professional relationships with other companies that are owned by creatures such as himself. This is the reason why he has the creature secretary separated from the human one because he would like to avoid having fragile humans in the crossfire in case a business deal goes sideways. The human secretary only deals with human-owned companies. 

Overall, Reo is a very wealthy man with many talents. He is the owner of very successful businesses and keeps up with the time of the market. 

Reo has a higher chance of falling in love with one of the workers in one of his own businesses, especially if you have dealt with him and know him personally. He is very aware that he is a piece of work and a high-maintenance individual. You would catch his eye especially when you don’t let him have his way with you, even if he is your boss. He likes someone who isn’t afraid of him and able to hold their own. 

He likes working for your love. If you have feelings for him and don't want to date him because he is your boss, he will offer to get you a spot at Nagi’s video game company, “Hassle”. He will make it work if he is genuinely interested in you, working out the obstacles between the two of you.

He is also one of the scariest vampires to get interested in you. He is a very persistent and determined man, and he wouldn’t give up until you fell in love with him as well. You are going to fall in love with him, one way or another. 

Vampire!Seishiro Nagi 

Seishiro becoming a vampire was by pure accident. Reo fed on him and healed his wounds to avoid suspicion, which is why he had Reo’s blood running through his system when he died. He was a farmer before turning into this creature. 

Seishiro cut him off because Reo was constantly on his back and treating him like an experiment ever since realizing that his compulsion didn’t work on Nagi. He knows that Reo is secretly terrified of him.

Nagi is beyond strong both physically and mentally, so even when he was younger when it came to this life, there were multiple occasions where he had gone head to head with the elderly vampires. What he was lacking was experience, and how to use his skills effectively to their full potential. 

Nagi often stole from humans. It is how he met Yoichi Isagi, a vampire a few years older than him after conversion. Nagi didn’t like working for his food, so he ended up stealing others’ hunts, but that time he didn’t realize it was actually another vampire that was disguising their scent as a human’s. It was surprising for Nagi to see Isagi chasing him and aiming at him with his hunting weapon when Nagi attempted to steal a bear from him.

Seishiro met different people who became his friends in the same forest he had taken a liking to because it was peaceful and there were plenty of animals to hunt for food. Seishiro was good at replicating noises from other species out of boredom. He howled on a full moon night, causing a lone werewolf to appear only for the two to stare at each other in silence. Neither of them was suspecting the other. A vampire howling perfectly like a werewolf. Nagi did have to come to an agreement with an older werewolf, who also lived in the enormous forest, on sharing it. 

He has learned a lot from the different people he has encountered during his time in the forest. Eventually, Reo and he made up. 

Nagi is a co-owner of a blood bank company, along with Reo. He himself created a video game company under the name “Hassle”. He was getting bored with the games that were already out and wanted something harder to beat. He did manage to create the kind of games he wanted and gained a reputation for players like him, who wanted challenging and harder games. Hassle does offer your normal typical game levels, but it does provide the option of buying a harder version, in which it is more complex to beat and finish the game. 

He is also a professional gamer on the side, and often received offers to advertise them. He will be the most honest and blunt person giving his review for an opinion on a game. 

He is most likely to fall in love with a fellow gamer through collaborations, with someone at his job or even working underneath Reo’s company. You have to be someone special that stands out in some way in order to catch Nagi’s eye. 

If you are human dating him, he wouldn’t even try to hide that he was a bloodsucker. He would warn you to not drink from his bottle because there is blood inside. If you didn’t listen, that's your fault. 

Overall, he requires a lot of patience to deal with in order to build and maintain a good relationship with him.
