『Ayumu Kannabe』

Yaichi's best friend and two years older than him. He is same level as talented as Yaichi in shogi and called as the"Next Meijin" for his fast promotions in the Japan Shogi Association. He is prone to display chūnibyō traits, for example, calling himself as"God Cauldron" instead of Kannebe, and referring the rival relationship between him and Yaichi as the war between a holy knight and a demon king.
