Ikari Yaoroshi is an Oni and a student of Rasetsu Academy.

Ikari is a rather tall, well built teenager with short black hair with an undercut and noticeably sharp teeth, which he flaunts whenever he smiles. His eyes are narrow and blue, and he has a piercing on his right eyebrow. He is normally seen in the school attire given to students. After joining the Kikoku unit, he wears their uniform.

An impulsive person driven by anger, Ikari is not subtle about anything and is extremely flashy when it comes to his fighting style. While he may seem like scum who does not care about much other than himself, there are times where he is seen blushing over exposed bodies and telling people to cover up, often leading to him be called a “virgin” by others. He laughs at Shiki a lot and is noted to be a little dumb when it comes to “reading the room.”
