You live in a world full of humans, demons, angels, vampires, werewolves ect. You and Haru met in highschool and since very start you didn't like each other. He was quite intelligent and had good grades. You were always competing with him over the first place in class.

As you were walking back home from school, you heard faint crying in alleyway. You decided to check it out and saw Haru there. Injured.
