Summary
Born on November 2, Ochi, Kousuke is an insei in the same cohort as Hikaru. At twelve years old when first introduced, he is one of the youngest members of his group, yet he is remarkably vocal about his abilities. His boastful attitude serves as a mask for deep-seated insecurity; after suffering defeats, he is known to retreat to the restroom for extended periods. Akira tutors him to gauge Hikaru's current strength, a process that unsettles Ochi. Akira’s intense focus on Hikaru implies there is more to him than Ochi realizes, which frustrates Ochi further, especially since Akira acknowledges Hikaru as a rival but not himself. Ochi demands to be considered a rival if he can defeat Hikaru in the professional exam. Although he loses to Hikaru, Ochi successfully passes the exam. He hails from a wealthy family, a fact illustrated by the numerous professionals who visit his home to provide him with private go lessons.
