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. Although he is not particularly intelligent, the Oni will decide to put in the effort when asked of him. The members of the Arataki Gang have great respect for him, Kuki Shinobu however seems to have a hard time managing their affairs because of his incompetence.

Itto has become mostly liked by Inazuma City's people, especially children, but is at odds with the Tenryou Commission despite his mostly harmless antics and pranks. The man will always take pride in his heritage and does not care for those who discriminate against his kind, though he will personally 'thank' those who call out the sexual advantages of being one.

As a self-proclaimed Red Oni, he appreciates the sacrifice made by his Blue Oni brethren for ensuring that one could be accepted into human society in the present day and is even willing to share the results with them as thanks for their efforts. This respect of his has made him always remember 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, and making contact with one can cause significant shock while consuming them can cause him to be bedridden for prolonged periods.
