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'.

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 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.

Although Ouza initally contemplated letting Akira win the match as a form of encouragement, he is angered by Akira's nonchalent attitude and decided to crush him completely. Akira forgot the safer strategy which could have won him the match, in order to show Hikaru his play. While the first snowflakes that mark the arrival of winter fell, Sai muses on the symbolic link between Hikaru and Akira and likened the presence of Akira as being placed there by God to help Hikaru on his path.

Yuuki Mitani decides to go back to the Go Club.

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 Honinbou continue their set of matches for the Honinbou title. They are on their final match, both having won the same number of games. When Ogata plays a sealed move for the first time, will he be able to follow up his actions and defeat Kuwabara?

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.

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 match between Hikaru and Akira comes to an end. Hikaru tells Akira that one day, he will tell him everything. At night Hikaru has a dream, with a surprise visitor! At the end, the song “Get Over” is played as we see everyone throughout the series. The Go world is changing and a younger generation has arrived!
