Keito is an introverted young boy who finds solace in a select few activities, such as reading books. He possesses a limited circle of friends, but he doesn't actively seek to expand it. In fact, he finds comfort in being apart from others, and this seclusion doesn't evoke any sense of loneliness within him. He has smooth, dark, moss-colored hair that is parted in the middle and cut short just below his ears. His eyes are a light yellow-green. And he wears grey rimmed, thin glasses.
