Yet another insei in the same group as Hikaru, Ochi is one of the youngest (12 years old when introduced), yet very outspoken about his ability. His bragging about his strength hides his insecurity; after each loss he is known to disappear into the restroom for long periods of time. Akira tutors him to find out about Hikaru’s current strength. Ochi is unnerved by Hikaru because Akira’s obsession about him seems to suggest there is more to Hikaru than what Ochi knows. Ochi is also angry that Akira acknowledges Hikaru as a rival, but not Ochi himself. He demands that Akira view him as a rival if he can defeat Hikaru in the pro exam. Ochi loses to Hikaru, but does pass the pro exam. He comes from a wealthy family, as evidenced by the number of pros that come to his household to tutor him privately in go.
