I thought Kenichi needs to do training but Apachai also needs it. After failed to train Kenichi properly, he devoted himself into strict training to help himself to go easy on someone during a fight. Every time he launches his kick or punch it will turn into deadly attack. Kenichi has been the victim of Apachai attack for a while now. From my perspective, Akisame is the best teacher follow by Sasaki and Ma sensei. I still remember one of Ma sensei technique that charges toward Miu while rubbing his head on her chest. That’s the best technique I’ve seen so far. Though, Shigure is quite good but she almost the same as Apachai since she also sparring in her serious mode. Oh, Miu’s teaching is the best if you count her as one of the teacher. To be taught by a pretty girl is not a bad idea after all.
