Hikaru no Go

As the match between Hikaru and Ochi draws near, Ochi becomes more and more annoyed with Akira's obsession of Hikaru. Therefore, Ochi demands that Akira recognize him as his rival and permit him to join Toya Meijin's study group if he beats Hikaru. Akira agrees to the condition, but when Ochi mentions to Hikaru that Akira is teaching him, Hikaru realizes that Akira will officially recognize him as a rival if he beats Ochi.
