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.

Hoping to win Kenichi's affection, Izumi seeks for Nijima's aid and ends up paying a visit to Ryouzanpaku.

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

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

Berserker has been defeated by Hermit, so Kenichi challenges Odin to a second fight. Ryoto accepts the challenge and the long awaited battle begins. Kenichi makes full use of the training he had received from Furinji-sama. Kensei eagerly watches the fight between First Fist Odin and Kenichi from a distance.

Unable to evade Ryuto's punches at all, Kenichi starts to counter attack by constantly changing his fighting style, imitating his masters' personalities (to their combined horror and amusement).
