Do not bother with this anime. Seriously. It has one merit: It is almost entirely casted by very bouncy, curvacious females who love being flirty and 'erotic' and all that.
Outside of that this anime lacks any merit. It's horribly plotted and directed. It leaves one going "So uh, what?' at the end. It tosses in dozens of one shot subplots that really don't even feel remotely relevent (And are really bad to have in a 13 ep series). It's amusing at points but just not worth the effort. If you really want to get the experience, just go buy some soft-core anime porn and save yourself the bother of all the filler this anime sticks in.
Unless you are really bored or horny and someone buys this anime for you, it's just not worth the effort.

The series had only two really strong points in my opinion. Hatsuki and the opening theme. Unfortunately only one doesn't get screwed over in the end.
Take a wild guess which. >_<

Just saw this at the local anime con (and boy am I tired. Damn getting old). In any case, two episodes was too much. The first is boring and the second is like it's own little story that doesn't really connect with what happened in the first. Almost like Abenobashi except without likable characters or overall plot that can be recognizable. After watching two episodes I have no desire to watch any more.
