Story: 6
The story of this anime is lacking. I'm sorry. I'm going to say it. It's cliche, repetitive, and predictable. However, at the same time, it's somehow intriguing in a way I can't explain.
Also, Kenichi was bullied as a kid but we don't really get to see any of that. It kinda stunk.
Art: 7
There's nothing wrong with the animation but nothing that special about it either so I'm giving it a 7.
Sound: 7
I really felt like giving this an 8 but I stuck with a 7 because so many more animes have a better soundtrack. But I liked the music. It fit.
Character: 6
There isn't much strong character development, so I'm giving it a 6. Obviously Kenichi changed but I don't feel as it should get a higher rating. I dunno. I'm sticking with a 6.
Enjoyment: 8
I enjoyed it. Watching it, I strengthened my own skill as a martial artist as well as enjoyed some of the funny scenes. I really liked this anime and I have rewatched it (all 50 eps) ten times. I don't really know what's so great about it, but I enjoy it.
It is funny. It has awesome fights. I like it and you should see it.
Overall: 9
I don't know what else to write here. I enjoyed it and I recommend it. So yeah.
