Protect the Name! Attack of the Dojo Challengers!.Kenichi finds that he cannot land a successful hit on Miu for fear of her counterattack. Honoka spends the day with Apachai and Shigure. Sakaki lectures Kenichi on the importance of landing the first blow in any fight. While Kenichi and Miu are left alone rivals from a karate Dojo break into Ryōzanpaku Dojo to challenge their karate master, Sakaki, but with only Kenichi and Miu present, Miu declares she will fight in Sakaki's place. However, Kenichi finds his courage and steps in to protect Miu and manages to land an impressive blow to his much more skilled opponent. Sakaki then arrives to protect his student and shows his own monstrous power by defeating the entire group of challengers in only a few seconds. Kenichi is praised for managing to hit his opponent but realises Sakaki had been secretly watching the entire fight. Kenichi also learns how the dojo makes money, first by charging their challengers money to take part in fights, and then charging them a second time for treatment at Akisame and Kensei's medical clinic.
