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.

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.

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