The attacks on Kenichi are now becoming a daily occurrence and one day his opponent ends up pulling out a knife against him. Because it was his first time against a weapon, Kenichi freezes up, forcing Miu to save him. Now Shigure-sensei, the weapon specialist, has now decided to teach Kenichi the basic art weaponry.

Takeda Ikki, the puncher from the Ragnorak gang, is still searching for Kenichi but has had no luck so far. So he decides to hold some of Kenichi's "so called friends" hostage to lure him out. Now it is the time to see if Kenichi's training on Muay Thai, with Apachai, had an effect.
