Let's see...so you are telling me that there is this secret programme in Japan training teachers in the art of kicking ass and sending them to problematic schools to teach their bad students while hiding the teacher's identity? Please tell me how this will make a good manga? But whatever magic Fujisawa Tohru did, it worked!
I've read a few Kamen Rider mangas in the past so the concept is pretty much the same. Intead of a Masked Rider kicking mosters in the head and making them repent, this time its a Masked TEACHER kicking STUDENTS in the head and teaching them discipline. And its not
that bad actually.
The storyline is ok. Kinda average. Simple, not complicated and has a lot of punchy-punchy and kicky-kicky moments. Actually the whole story is driven by punching and kicking. Fast paced and full of action would be an accurate description.
The characters in the other hand are somewhat different although they consist of the typical action, seinen, school life characterization. But yeah...they're alright.
The artwork is nice and it has that badass, shit's-gonna-go-down kinda vibe. Its well drawn and is nice to look at. Pretty impresive.
The enjoyment factor is there and it will appeal to most shounen or seinen readers (if you like punching things, you'll love it). The comedy factor is stale though. There are a few funny parts here and there but they aren't anything worth shitting your pants laughing about. It also has zero gore and zero sexual content (so you goody goody two shoes got lucky).
In short Kamen Teacher is good but not epic. 7/10.
