Quite a good read so far. Though this manga is far from finished, what I've read so far is pretty good.

This manga is somewhat unique from the standard harem non-sense in the sense that the male protagonist is actually running away from pervy stuff. A very interesting concept indeed. Not that less pervy stuff happen, quite contrary - he is drowning in a sea of women with exposed breasts and asses and has to employ special powers of his own in order to run away.

The main concept is that he is diagnosed with a rare "hentai" disease that will kill him if he is exposed to too much sexuality. So he trains hard (and he is possibly the strongest character in the manga so far) so that he doesn't get killed by his rare disorder.

But like his unlucky destiny unfolds, instead of going to a all boys highschool he instead is sent to an all girls highschool where all the fun is. Plus that each year has its own "dragon" female with insane powers and an army of followers that battle for supremacy. He is stuck in the middle and as the manga unfolds, all of the strongest and pretties girls want to follow him. One even begs him the entire manga to train her, to his discontent.

A great read (and will probably continue as such)
I highly recommend it to fans of both ecchi and action manga.
