Toya Akira

Japanese name:

塔矢 アキラ

Akira Toya (塔矢 アキラ Tōya Akira) - Hikaru's biggest rival and Kaio Middle School student. The son of Koyo Toya, Akira is already a very strong go player when Hikaru first begins playing. Akira is amazed by Hikaru's seemingly impossible ability and becomes obsessed with discovering the secret behind Hikaru's strength. Meanwhile, Hikaru is impressed with how serious and focused Akira is for being only a 6th grader like him when they first meet. As the series goes along, the plot brings these two characters together to play each other under many circumstances, each time adding to the mystery. Like Hikaru, Akira also gets taller throughout the series. He is voiced by Sanae Kobayashi.
