Hikaru no Go volume 23 features story by Yumi Hotta and art by Takeshi Obata.

Hikaru is in the toughest battle of his life when he faces Ko Yong Ha, Korea's top player in the Hokuto Cup tournament. The stakes, however, aren't for personal glory but for something far deeper, something that differentiates a mere game from a way of life. Hikaru knows what this means to him, but will he understand what it means to the new wave of go players and, indeed, the game of go itself?
