Hikaru is torn by the decision he has to make. An unlikely saviour came in the form of Kaga who proposed that Shindou quit the club after showing them how strong he is - by playing three of them at once (Mitani, Tsutsui and Kaga). Hikaru prepares to take the Insei exam. Having bumped into Hikaru at the institute, Waya's interest is piqued by Hikaru who declared to surpass Akira and remarked to Isumi that Hikaru will most probably pass the exam.
Sixth grader Hikaru Shindo stumbles upon a mysterious Go board with a blood stain on it. Before he knows it he's hearing voices, one voice to be exact. The voice of an ancient Go instructor, Sai of the Fujiwara. Sai occupies a space in Hikaru's mind. Hikaru is the only one who can see, hear, or talk to Sai. Sai's one and only desire is to play Go. But he can only do that via Hikaru's body. However, Hikaru has no interest in playing Go. Will Hikaru allow Sai to play? And who is this mysterious young boy, Akira Touya?

With the recent defeat of the Meijin's son, Hikaru goes about his day normally. However, Akira is obsessing over the game he lost. He won't do anything but stare at the Go board and replay the game that he lost. When he gets word that Hikaru is at a Children's Go Tournament, he rushes there hoping to confront Hikaru and ask for a rematch.
