Kabaji is Atobe's faithful follower and childhood friend. But despite his appearance Kabaji is a very powerful player. His simplemindedness proves to be to his advantage because he can imitate his opponent's play style by just observing them. Kabaji rarely talks, and he is often heard saying "yes" to Atobe.
