Kuroko-chan.

Synopsis

Kuroko Yuki is an otaku girl with a severe case of "chuunibyou" who constantly finds herself as the butt of the joke, both at school and at home. Living in a household of geniuses—a sister who's the strongest woman alive, a brother with an IQ of 300, and a musical prodigy younger sibling—Kuroko's daily life is a series of cringeworthy social failures. From sending family messages to her class group chat to bombing hard at karaoke, follow the high-tension, hilarious, and somewhat pitiful daily life of the lovable failure, Kuroko-chan!
