Akari invites Hikaru to the Haze Junior High festival. Hikaru reluctantly goes, but cannot find Akari anywhere. So, while walking around he stumbles upon a group of kids around a Go board. Tsutsui, the head of the Haze Junior High Go Club, is holding a competition. The prize is a book entitled "Assorted Tsumego from Touya Meijin's Matches". After seeing this Sai is eager to win it. But, can he with the sudden appearance of the Shougi captain, Kaga?

Hikaru is now in Haze Middle School and joins the Go club. Akira Toya is now in Kaio. He pays a visit to Haze and challenges Hikaru to a match. Will Hikaru accept to play him?

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?

Players who have been following Sai's net matches attended the 20th International Amateur Go Tournament in Japan. A commotion occurs at the mention of Sai's name as everyone is trying to who out who he is. The commotion caught the attention of Ogata and Akira. When Akira and Sai engaged in a match over the net, the former is reminded of his first match with Hikaru. Akira discontinues the match so as not to disrupt the ongoing tournament but fixes a date for a match with Sai which happens to be on the first day of Akira's Pro exams.

Kishimoto (Kaio's first board) played a match with Hikaru to find out his real strength and expressed his puzzlement as to why Akira sees Hikaru as a opponent when he's not as strong. Through Kishimoto, Hikaru realises the widening gap between Aikaru and himself and that it would be impossible to catch up with Akaru with Hikaru's current pace. All fired up, Hikaru decides to start off with enroling in the Insei program with becoming a Pro and defeating Aikra as his goal. However, he failed to realise that Inseis can't participate in Amateur tournaments. Thus, he's being forced to make a choice between being a Insei or quitting Haze Jr's Go Club.

Hikaru aims to progress to the first class of the Insei program where Waya and Isumi take the top spots. Both of them wanted to pass the Pro exams quickly this year, due to various personal reasons. Ogata feels that Akira doesn't seem to have much of a fighting spirit recently and bring him to the insitute to show him that Hikaru had gotten into the Insei program. It succeeded in provoking Akira to rev up his pace. Hikaru learns of the new dan series that is to take place in The Room of Yuugen and witnessed for himself, the imposing presence/aura of the room. Meanwhile, the end of the episode marks the start of Akira's first dan match with Zama-sensei.

With help from Sai, Hikaru overcomes his weakness and finally makes it into the A league. Back at school, Kaga and Kimihiro have already graduated to HIgh School. Now that Hikaru's in the A league, he's slowly reaching his goal of 16th. He's even able to defeat Fuku, someone who not even Waya can defeat. Waya is Hikaru's next opponent, and Waya's confident that Hikaru will lose. That is, until HIkaru accidentally blurts out what the online user Sai said to him. Can Hikaru defeat Waya and prove to Waya that he isn't Sai at the same time?

The top 16 in the A league all take part in the Young Lions Tournament. If Hikaru can manage to get past the first round, he'll finally get to face Akira again. Meanwhile, Isumi faces an old rival, and everyone wants Isumi to put him in his place. As Sai and Ogata monitor Hikaru's game, they become shocked when Hikaru turns a bad move into a good move. However, when the round ends, only 3 Insei will have made it to the next round.

Ogata and Kuwabara are anticipating their matches for the Honinbou title, both anxious to greet the upcoming wave of pros in the Go world. Meanwhile, a guy who has won many college titles for Go and is well-known among the Insei is planning on taking the Go test.

Isumi has gone on undefeated, while Hikaru has lost only one game so far. The time finally comes for them to play each other, and only one of them can win.

The Pro Exam is nearing its end as the last three matches arrive. Ochi, Waya, and Hikaru are currently the top three, and Ochi is at the point where he'll pass even if he loses all of his matches. Hikaru and Waya must still be careful, as a loss or two could cause them to lose their spots.

The long awaited day has finally arrived. Hikaru Shindou V. Akira Touya! The two reminisce about the past and the last time they played. It was a little over two years ago. They have both grown stronger since then. They sit down. Hikaru places one black stone and Akira places five white ones. Hikaru is black and will go first. Akira is white and will go second. Hikaru places his first stone down on komoku. Both of them are excited and the match they have both been waiting for has finally arrived…
