Aki

Protagonist of the story. On first look he looks like a normal human but under his hoodie jacket hides the two small horns on his head. He changes to his giant S class werewolf form when his emotions overwhelm him. In the flashback he was a weak when he was young and his S class soul is sought after by others. His parents were "killed" by Bellze but on the defeat of Bellze their souls returned and they revived. His weakness is that he must sleep after he uses up his soul form.
