Inukai has blonde spiked up hair, with a red jacket with a black hood, black arm covers, and pants, with red sneakers.

Inukai is casual and outgoing even to people he's met for the first time. Unlike most Darwin's Game players, Inukai believes in being fair, which is also his weakness.

His Sigil Speed Star allows Inukai to move at high speed, which he uses in conjunction with his martial arts. He mainly uses it with his legs, as he hasn't trained it to work with full body techniques.
