If you’re looking for an anime which is purely comedy, this could be the one for you. Perfect Girl Evolution is about a girl who enjoys the darkness and is psychologically allergic to beautiful people. Unfortunately for her, she is to stay in a mansion with four bishounen.
The core idea of the story lies in turning Sunako-chan into a perfect lady and (perhaps, through) developing love between her and one of the guys. But the anime, being heavily comedic, digressed much from the main idea.
Nonetheless, it is highly enjoyable for those who simply fancy comedy despite its ridiculousness. A light anime with high rewatch value as it is hilarious. There’s not much to be appreciated about the art, though, seeing that it is rather rigid and the supposedly good-looking guys really look like girls.
