It starts of funny and the idea seems original enough.Yamada the main character is a 15 year old girl who has apperently set her goal to have 100 sexpartners, ofcourse somebody has to be the firstso, where to start....
Halfway through the series it's still funny, but she's starting to annoy me.
I'm not much of a fan of tsundere girls and she's getting worse and worse along the way.
The story covers about 2 years in these 12 episodes, so you might call it character development... Anyway.
The animation is pretty good, same goes for the sound.
The characters are mostly pretty standard as it seems required in this type of anime, but it didn't bother me too much as they're just present enough without annoying me.
There are some anime's that go over the top and try to force the stereotypes on you with way to much obvious behavior and they can even spoil the fun of those stories, but none of that here.
Altogether I enjoyed watching it and had quite a couple of good laughs! =)
It still bothers me though how prudish they seem to be in Japan.
Sex is such a scary thing and shouldn't be talked about and yet, when it really comes to it... So, we're naked now, let's just dive right in! Forget te exploring of each others bodies or doing some foreplay first. But anyway, that's not the main point, is it?
If you want any of that you should look up a different category of anime.
(Or no anime at all.)
So to keep it short and sum it up again, if you like mild tsundere, a bit of slice of life combined with a lot of fun, ecchiness and indeed some romance too, no need to skip this anime.
