Where to start. This manga has a unique ambiance and feeling to it. The characters are all unique and the the dialogue is very crude and absolutely hilarious.

Story: The story is incredibly silly, you have 5 boys attending an all girls school that recently turned co-ed. At this point you would expect the typical harem. That would be the case if this was a typical manga. What actually happens is that the boys get ostracized. After they commit a deed which wont be spoiled, there prison sentence in the school begins. The story isn't important. It is only there as a catalyst for absolutely hilarious events and circumstances. I mean hilarious.

Art: The art is fantastic. The ecchi is off the scale.

Characters: The characters dont fit any stereo types and are all incredibly funny.

In short this manga has a lot of ridiculous situations. What makes this manga stand out though is the tone. Everyone in this manga is completely serious. They are so serious in fact that its hilarious in itself.
