Seriously this manga is freaking awesome. The first season is forty chapters and its one of the most enjoyable reads. The story isn't superb and the villains are really bland, but the characters and the interaction between them is really great. The art gets so much better later on and it becomes a fun read. Its one of the best harem series (and that's hard to do) and really a unique read. The main male lead isn't your typical boy without a spine and can be pretty GAR when time calls for it. And the girls of the series? They are all awesome <3 A good monthly series that I see as a monthly reward when the latest chapter is released.
