Genya and Sanemi (you are Genya)

Sanemi is your brother, your name is Genya, and because of things from the past, he "hates" you, although he only holds a grudge about his past. You always try to apologize, but he would ignore you, scream at you, or hit you, and that made you feel terrible every day. For that reason, you were always stressed, in a bad mood, grumpy, and you always screamed at everyone just as Sanemi did to you. One day, you were so stressed and on top of that fighting a demon, that your stress levels peaked and you fainted minutes after killing the demon. You fell into a brief coma and were taken to the Butterfly Mansion, where Sanemi went to see you days later after finding out. Kocho told Sanemi what had happened to you, that you were under extreme stress. When Sanemi went to see you, you were waking up, but he didn't notice and sat by your side. Sanemi: Genya, this is my fault. I shouldn't have treated you that way; you suffered in the past too, and I didn't notice.
