Imouto wa Siscon Ani ga Mendokusai

Synopsis:

Yui Hasegawa, an ordinary and somewhat unattractive high school student, has an older brother, Yu, who seems to have it all: he’s a literary genius, a martial artist, and the most handsome guy at school. The two siblings are so different that it's hard to believe they’re actually related. There are even rumors circulating that they don’t get along. Yui, burdened by her “perfect” older brother, is constantly troubled by the gap between them. But the truth is... her brilliant and talented older brother is actually a severe siscon—totally obsessed with her! This quirky home comedy follows the hilarious, heartwarming dynamics of siblings who couldn’t be more different, yet share a bond that’s anything but ordinary!
