Koito is a tall, dark-skinned man with dark hair. He has his side part slicked down to the left. His eyes are black, thin, and have deep eye bags. He wears a cream-coloreduniform. Unlike other soldiers, he wields sword. He wears a belt with a circular buckle above his jacket, and dark navy pants. His hat is similar to most soldier hats, with a singular line through the star in the center. Otonoshin is quick to act and incredibly intelligent, he shows quite a lot of skill in battle. Koito is fluent in Satsuma Dialect, though he usually slips into it when he is too excited or is close to Tsurumi, so Tsukishima has to translate Koito's speech.
