The finals of the Third Annual Junior High Go Tournament - Kaiou Junior High V. Haze Junior High. With a score of 1-1 it is up to Hikaru to win it for Haze. Can he do it? And what will happen when Akira spots Hikaru playing?

A boy named Yuki Mitani solves a challenging problem on the Haze Go club's posters. Hikaru knows they need a third member really badly, and tries to convince Yuki to join. However, he soon discovers Yuki's true strength.

Hikaru, Tsutsui, and Yuki all manage to defeat their first round opponents. But, the next next round won't be so easy as they face of against Kaio. Hikaru is excited about facing Akira, but wishes he had more time to get stronger. However, Hikaru soon learns during the break that Akira was treated very harshly in Kaio's Go Club, but he never quit because he was chasing after Sai. Touched by the story, Hikaru informs Sai that he will play Akira instead of him.

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

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.

Hikaru is losing the game in his anxiousness to win it. He freaks out when he realised that he didn't necessarily have win the game to pass as the purpose is for the examiner to gain an idea of his strength/potential. In reading the kifu, the examiner is amazed that Hikaru played the way he did during the 3-way match (with Mitani, Tsutsui & Kaga) and passed him. Hikaru unwittingly blurted out that Akira pursues him as a rival and received a cold reception from the Inseis who then see him as a threat. Waya and Isumi questioned Hikaru's validity when observing Hikaru's matches. Hikaru is shellshocked to find out that Kishimoto didn't even make it up to the upper half of the Insei class when he was an Insei and had quitted trying.

Hikaru takes the prelims to qualify for the Pro exams whereas Waya/Isumi are admitted straight to the finals being among the top 8 of the Insei program. Hikaru is intimidated by Tsubaki, a really loud and brash guy, who turns out to be his first opponent. Tsubaki plays mind games with Hikaru and won the match. For Hikaru, the loss highlighted his inexperience with playing with adults since starting go and it represents a hurdle he has to overcome to reach his goal.

Hikaru and Tsubaki must face each other in the Pro matches, and Akira begins teaching Ochi in an attempt to learn how strong of a level Hikaru is playing at.

Realizing that Hikaru is getting stronger, Ochi swallows his pride and decides to ask Akira for help. When Akira tells Ochi about the game Hikaru played against Su-Young, Ochi realizes that Hikaru is a serious threat and that three weeks might not give him enough practice. However, Ochi still doesn't understand why Akira is obsessed with Hikaru, forcing him to show Ochi the match at the Go Salon from two years ago, the game where Hikaru destroyed him!

Hikaru continuously ignores Sai's worries of his leaving and ends up allowing Sai to engage a drunk Ogata in a Go match. The next day, Sai begs Hikaru for a game, but something happens during the game that will change Hikaru's life

The Go world is moving. Everything is changing. Hikaru has won his first comeback match and dives into his next one. Isumi is taking the Pro Exam and is on his way to becoming a pro like Waya, Hikaru, and Ochi before him. Akira is beating high level dans. Ogata has taken yet another title. The Go world is shifting; a new wave is coming with Akira in the lead. But Kuwabara will not allow them to surpass him just yet...
