Oh GJ-bu..lets start by saying its a cute,amusing anime(for some..for some it isnt).I personally enjoyed it.
The story is that a boy gets kidnapped by 4 girls who all aparently like him(?) and he is forced to join their club.Follow the MC and the 4(later in series 5 and ocasionally 8) girls doing funny things.On a more serious part of the review its mostly making fun of the feminine-like MC,bitting and punching him for the amusement.
The sounds were ok...not too great not too poor.The music was good and catchy just like in th most comedy-type school animes.
The characters were a bit plain in my opinion.Why is that you think?Well this is why: they do the same things countlesly in one episode,getting boring and thus they are plain.They all have some kinds of unique traits but still.
I enjoyed this anime.It was short and funny,with a nice art going along with it.Tho it would have been more enjoyable if the characters would have been better designed.
Overall i would recomed this anime.Why?It's short and entertaining(again for some,depends on person).So go watch it if you dont have anything better to do.
