Akira is too good against everyone at Kaio's Go club. The members don't take this sitting down, as three of them plan to take him down.

The Go Sallon Yuki goes to doesn't mind giving him money for winning games, but they are tired of him cheating to get it. They hire a skilled player who pretends not to know anything about Go to teach Yuki a lesson. Unfortunately, Yuki falls for the trick and ends up betting 10,000 yen (about $90). Can Yuki manage to defeat this skilled player?

Akira is quite tense at the fact that he is finally facing Hikaru, or rather Sai. All is going well, until Hikaru notices a point that he thinks should be played and Sai doesn't play it. Determined to find out why, Hikaru takes over and plays it. Sai reveals that the move might have worked, if Hikaru was good enough to back that move up. How will Akira handle the situation when he sees Hikaru really play?

Everyone is anxious to find out just who this mysterious user named "Sai" is. How long can Hikaru keep playing before he gets caught?

Akira skipped his first match of the Pro exams in order to play the match against Sai on the net. Akira is perplexed over the identify of Sai which he thinks might be Hikaru while Ogata has his own thinking. Players all over the world are observing the match. Though Akira lost the match, he feels as though he had finally caught up with 'Hikaru'/Sai. When Akira heard from a Go cafe customer that Hikaru was sighted at an internet cafe, he races to the site thinking that he might be Sai. Hikaru denies he's Sai but gets ruffled when Akira seems to disregard him as a opponent. The episode ended with Hikaru saying 'If you keep chasing after an illusion of me, I'll pass by you eventually'.

Hikaru is slowly, but surely, getting better as evidenced when he beats Mitani in a game though with a handicap as well as Tsutsui. To play go with Sai, now that they decided not to play internet go anymore, Hikaru tries to get his gramps to buy him a go board/stones. When Hikaru beats a strong opponent at the go school, even to the astoundment of the teacher, he finally understands that one can only judge how strong others are when he's strong himself. He bumps into Kaio's first board when he's browsing a bookstore and the latter pulls him away to a match.
