Arataki Itto is loud and proud descendant of the crimson oni, Itto is also the leader and founder of the Arataki Gang. While not a villain, his reputation as a delinquent in Inazuma City leaves something to be desired. Despite only being part-oni, Itto is extremely allergic to beans; making contact with one can cause significant shock, while consuming them can cause him to be bedridden for prolonged periods of time.
