After watching Kenichi defeat Daimonji, Tsukuba, the strongest member of the karate club, gets suspicious of Kenichi's abilities. At the school Miu, joins the girl's gymnastics club and soon becomes the center of attention after displaying her abilities at gymnastics. Kenichi desperately tries to avoid Tsukuba, but is soon caught and gets beaten to a pulp. Seeing Kenichi repent his loss to Tsukuba, Akisame decides to start training him in some martial arts techniques.

Kenichi decides to spend the entire weekend at the Ryouzanpaku dojo and train for his imminent fights. His little sister then goes to check out this dojo, to see what kind of torturous things he's going through.

Kenichi feels uneasy about how he should express his feelings to Miu. After Kisara hears of Takeda's defeat Tsuji Shinnosuke is sent to kill Kenichi, however he invites him to join his gang instead. When Kenichi refuses and debunks his way of thinking, Shinnosuke challenges him to a fight.

All of Kenichi's attacks seem to have no affect on Shinnosuke. Even though Kenichi is stronger, his opponent has more fighting experience so he is still at a disadvantage. Miu is not allowed to come to his aid because it would hurt Kenichi's pride. Kenichi becomes careless and is knocked to the ground and is about to be torn apart, Takeda comes and punches Shinnosuke to one side and escapes carrying Kenichi back to the Ryouzanpaku dojo. To Kenichi's dismay his masters all criticise him for being defeated, because it means it will lead to further defeats. Niijima continues to spread his manipulated version of the news throughout the whole school. After his defeat has been revealed to everyone, he is constantly chased around by school delinquents. All of the masters at the dojo decide that Kenichi should be taken in as a true disciple of Ryozanpaku, meaning he should stay there and must live only for martial arts.

After his defeat with Shinosuke Tsuji, the masters decided to have Kenichi live with them. This would include 24 hour hell-like training. Kenichi accepts with the idea that he would be living with Miu under the same roof. Kensei later drags Kenichi do a "special training" with him by tryring to peek on Miu and Shigure's bath unnoticed.

Honoka decides to infitrate the Ryōzanpaku by herself, much to her despair.

Rivals from another dojo break into Ryōzanpaku to challenge their masters, but only with Kenichi and Miu present at the moment, they end up having to confront them by themselves.

The gang leaves with Honoka to a special summer spot.

Niijima puts his master plan to create his personal legion in motion.

Ragnarok's Loki and Siegfried capture Niijima and Kenichi goes for his rescue along Miu.

Hermit reappears eager for another fight against Kenichi, but he ends up having a sudden encounter with Honoka, unaware of who she is.

Loki kidnaps Honoka and attracts Kenichi to an old church, where he meets Hermit, and their fight begins.

During his fight with Kenichi, Hermit's tragic past is revealed.

Kenichi and Hermit's fight is interrupted by Loki, who using Honoka as a hostage, renders Kenichi unable to fight back, much to Hermit's anger.

Even after rescuing Honoka and breaking his ties with Ragnarok, Tanimoto is determined to finish his fight with Kenichi.

Renka discovers where Kensei Ma is living and appears in Ryouzanpaku, determined not only to bring her father back home, but to win Kenichi's heart too, much to Miu's jealousy.
