Arataki Itto

Despite appearing as "mean and overbearing," Itto is a kind soul at heart, apart from trying to pick a fight with Kujou Sara at every possible opportunity. He is not particularly intelligent, but can put in the effort when asked of him. He is respected by his gang and mostly liked by Inazuma City's people, especially children, but is at odds with the Tenryou Commission despite his mostly harmless antics and pranks.

Itto takes pride in his oni heritage and does not like those who discriminate his kind, though he loves when others call out the sexual advantages of being one. He appreciates the sacrifice made by his blue oni brethren for ensuring that oni could be accepted into human society in the present day, even wanting to share the results with them as thanks for their efforts. He always remembers the age-old pact between the oni tribes and never uses his strength for malicious purposes, refusing to terrorize humans and steal rewards that he hadn't claimed legitimately, though that doesn't extend to satisfying his sexual desires. Due to this pride, he is extremely competitive, although he knows when to concede.

Itto also has a habit of making names on the go and maintaining his appearance no matter how severe the weather can be. 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.
