Koito Otonoshin is a Second Lieutenant of the 7th Division. Koito is a tall, dark-skinned man with dark hair. He has his side part slicked down to the left. His eyebrows are usually furrowed, with two larger sections towards the center, and furrow wrinkles up his forehead. His eyes are black, thin, and have deep eye bags. Because Koito is from the Satsuma Province, which is located in the southern tip of Japan, his dialect slips out sometimes. This often happens when he is excited or nervous. However, this dialect cannot be understood by most Japanese speakers.
