All you little overboard fanservice ecchi kiddies will love this show :p
Storyline
Hmm.. The storyline is pretty simple with no complexity at all for both seasons. It's your usual harem anime with a tiny twist and that twist is the main character is allergic to all those females except for one o_O and that is where our story starts on...
So when I first started watching the show I wasn't all that impressed with it, even with all that eye candy ...*cough*. However I watched on and began to enjoy it more than I thought I would.
Music
The only thing I can recall is liking the opening and ending themes for the first season. The opening theme "Going My Way" by Yozuca had an upbeat catchiness to it which was a good start to the show. And "Koko ni Irukara" by Miyuki Hashimoto was peaceful in a happy relaxing kinda way.
Characters
I think the one that shined out the most was the pervy hilarious Kazuharu Fukuyama. He's like a parasite you didn't want attached to you but he's there o_o...I really didn't care for him at first but if it wasn't for this secondary character I'm almost pretty sure the show wouldn't be as funny as it was. His crazy antics and ways of trying to captivate....I mean capture >_> the ladies and the way the ladies, especially Kirie Kojima, take to him are rock your socks funny. Ya know I've really gotta hand it to Liam O'brien (famously known for playing Gaara in everyone's favorite ninja show, Naruto) for doing such an awesome job with Fukuyama. His vocal range amazed me in this show.
As for the other characters... well some could be more annoying than others at times including that one up there ^. But all in all they meshed well together to form a pretty good ecchi comedy.
Animation
I guess the animation is basic with a lot of bright colors. You won't find any doom and gloom scariness here.
Overall
Like I said all you little fanservice kiddies will love it. However just because there's nudity ...don't expect any raunchy hentai material O_o. And if you can't handle lots of pervy humor or it just isn't your cup of tea, this is best not the show for you. Other than that it's really good for a laugh if you are in need of one.
this anime will make you laugh so much that you will cry. i love this anime cuz it is super funny!... love funny stuff !!! ~ also i love it cuz it is just an anime that i watch ... i think you should totaly watch this anime in all it is HILARIOUS!!!
