==Overview==
Kenichi is easily defeated by Tsukuba despite his heavy training, and becomes depressed. With a desire to see him become stronger and more courageous, Akisame-sensei agrees to finally teach him martial arts fighting techniques; Kenichi is also put through more rigorous training from the four other masters. Sakaki-sensei takes a liking to him, so he teaches him a technique that a Sports Karate Style user is vulnerable to. Eventually Kenichi runs into Tsukuba and fights him again, and this time, because he uses the techniques taught to him, he emerges victorious. Little does he know what troubles he will face because of it in the future.
