Yoshinori Ume

Being the child of teen parents who didn't care about him, he didn't really have the greatest childhood. His mother left him and his father when he was 6 and his father was a huge alcholic. His only solice was his friend/crush, chiyo, from school and the new neighbor, tamiko. Eventually, yoshinori's father was arrested for unknown reasons. His neighbor, who at that point was a parental figure to him, ended up adopting him.

As he got older, he and Chiyo got more friendly and started dating. It was all going until prom night, Chiyo murdered her own abusive father. After that went down, Chiyo had become hellbent on experimenting on bad people and killing them. Yoshinori was willing to drop out of college, which had already stressed him out enough, to further this endevor. They were living happily ever after (not really Chiyo and Yoshinori's relationship became extremely toxic) they got married and had two kids, Akere and Jiro. Eventually, Yoshinori and Chiyo started fighting everyday. Chiyo then ran away after Yoshinori realized that their relationship wasn't that good and asked for divorce. Yoshinori took his two kids and they moved all over the place until they settled in living with Tamiko. He got a pretty average life now, a dead daughter (Jiro) and their daughter, Akere, has gotten kidnapped twice. But at least he got two bfs now.
