Story (Good)
The story runs in a typical sitcom style, with every "issue" solved in 30 minutes or less. Things usually start in a safe manner (like going to gym class or going karaoke), but by the end it just ends up all sexed up and wacky. Sexual innuendo's are all over this show. Thats part of this shows charm and makes it pretty entertaining (if you like that kind of stuff).
Art (Decent) --- Sound (Mediocre)
The art and sound is all pretty average for what its worth. Art is not too detailed but not too simplistic. It's very... AVERAGE. Although they drew the girls all cute like and hilarious, you can tell that everything else (backgrounds, static objects, etc) had less time taken to produce. The sound has typical anime comedy sounds but what helps out the most is the music in the show. It's all so very upbeat and happy, I could hear Kirameku (op song) over and over and it won't get old. Even after a year of finishing this show, I still enjoy that song as much as I did the first time heard it.
Character (Good)
This show doesn't have much in terms of sound, story, or art. So High School Girl's trump card to make this show remotely worth watching are the high school girls. With the lack of men in the show the girls all take center stage and make for some pretty unique moments. Particularly from all the innuendo jokes. Those moments are so wrong, its hilarious. The girls aren't even over developed as you would expect from an ecchi comedy. Rather they're all drawn like normal looking girls, which help enhance the comedy.
Overall if you enjoy a good ecchi comedy that more based on situational jokes rather than blatant fanservice with a few jokes. Give this one a shot. It is definitely for anyone who enjoys a dirty joke or two. And a special note: some of the funniest jokes are at the very end after the credits.
