Do you hate pointless fanservice?
Well you aren't alone. Our protagonist here fights this world of panty shots, boobs and such with only his martial arts and his gut.
Secret technique of the ape! put on some pants woman...

But seriously. that's the general synopsis.

why is this great?

non perverted protagonist
many bad asses (especially our mc, understanding one should develop both brain and body)
pretty good art ( some characters are pretty, some ugly, some ugly for comedy, at least some characters will suit you)
Awesome humor ( dude fighting vs fan service. Nuff said )
raging battles combined with comedy and fan service negation

Why may one shy away?

well to fight against fan service, there must be a bit of it at least ( mostly for humor )
a wide range of characters means some may not be your favorite ( cough second and third year leaders )
may not be family friendly
battle oriented not romance oriented

One should definitely try this manga out as it has many novel aspects and is very enjoyable ( for me ). Reading a chapter can bring a smile to a gloomy day. Manly battles with humor, fan service ( negation ) and cute moments. What are you waiting for? ( maybe a gloomy day to be cheered up on:P ).

I personally recommend this to be read alone, not at a library or cafe to avoid a tinge of compunction. but hey, if you like doing stuff like that go ahead. freedom eh?
