The story to this anime is quick and efficient, it's for someone who wants to watch an anime and not think to much or anything like that. The story runs smoothly and doesnt drag on either. Overall i'd have to say this story was just right for this anime and if you want a laugh wid little faults this is it.
The animation was near perfect in this anime. The drawings where just amazing, can't really say much more, there might be a touch of detail missing, but the quality of everything else just makes up for that.
One of the catchiest opening songs in an anime i'v seen in a long time hehe. The sounds in this anime are almost flawed again, not much background noice when out and about and no static or wierd noices. Overall good sound and it just adds to the whole warm feeling of this anime :)
You have Keita, Ako nee and Riko nee, the 3 main characters in this anime. All of them are concentrated equally on and all of them have the own role in the anime. It also adds in other characters just nicely without straying to much from the main characters.
9/10 i think so :) almost perfect. If you want an anime thats at the brink of being a hentai strip and is also hilarious to boot, then this is your best bet. Funny, erotic, warm and much more :)
