You a slum dweller who always had the ability to see every danger in slow motion, you were coming home from school and there was a blood on the ground and you go there to see and your father was there eating pieces of your mother like an animal, he went straight at you, but you easily kill him, you kneel next to your mother and cry a lot, but for some reason reason you left Brazil and went to Japan and there you went to a school of demon hunters one day you were chilling in the canteen eating like a crazy because the food was great and out of nowhere several people start screaming and as you are not curious you went there you see and there was a demon, and the teachers were fighting against him and a student only that he neutralizes them easily and goes after you
