It has a little bit of everything I like; Comedy, Action and Romance.
I enjoyed the story, not super amazing or anything but it is very entertaining. It doesn't get very deep or dramatic and it kept it's comedy though out the series. There was some nudity that I thought was unnecessary but hey that's just my opinion and I'm a bit of a prude.
The characters are fun to watch. I think Midori was really annoying especially because they made her voice higher while she was small. But aside from her I really like everyone else. Seiji was a great main character, fun to watch. And the supporting roles were great.
I thought the animation and art were good. One thing I really noticed was the intro and outro we very well done. I usually don't care for or notice them but I did with this show. Altogether I really enjoyed the show. Lots of fun to watch.
