Apachai is afraid of hurting Kenichi and trains to be able to hold himself back so he can teach Kenichi Muay Thai. At school Takeda and Koga continue to search for Kenichi with their friend Ukita the Thrower. Niijima informs Kenichi the person he will most likely be fighting is Takeda, a former boxer. Apachai believes the Muay Thai fighting style will be most useful against a boxer, and the training begins. During Kenichi's sparring Apachai fails to adequately hold back and accidentally kills Kenichi who is quickly revived by Akisame. After his recovery Kenichi suffers from amnesia and does not remember what happened. Elder teaches Apachai a method of holding back. Since he forgot about being killed, Kenichi gets ready to be trained by Apachai again, who manages to hold back his fists but ends up knocking Kenichi through a wall with his foot.
