Sister Princess is surprisingly not a bad anime. Its about a boy who finds out he has 12 younger sisters all of whom adore him. And its also hinted that they might want to be his wife. (your typical anime stuff). Its a relaxing, stress free anime that focuses on the day to day life of these siblings. There are also some supernatural elements here and there. Its a good anime to have as background noise. It doesn't require your focus. The voice acting in the dub is kind of silly. With the sisters all having bizarre accents. This was done in an attempt to differentiate them. Andthey are all likeable. They didnt shove an annoying tsundere in there for no reason.
