Swing Out Sisters

Swing Out Sisters (2011) is a animation directed by Toshihiro Watase rated 7.0/10.

It's finals time, but tests aren't the only things stressing out Yuuta, who's literally being smothered with affection from his beautiful sisters: Chiyoko, who is feminine, caring, and coddles him; and Chinatsu, a strong-willed tomboy who desperately seeks his attention by picking on him. Who will triumph in this sibling love triangle?
