My Least Favourite Theory At The Moment Since It Lacks Of Proof - Tumblr Posts

The policeman from Keiji's backstory is Sara's real dad.

I don't have a lot of proof apart fron haircolor and what Ranmaru said to Keiji:

"Are you the one who brought Sara here?"

Implying that Sara is here thanks to Keiji's wish.

Was Keiji's wish seeing the kid of the policeman for idk say sorry?

(There IS the possibility that the policeman got lied to that he was going to have a son)

(I liked better the theory that says is actually Shin the kid of the policeman but whatever all theories are valid until proven otherwise).
