Seishun

Atsuko is the 12 year old younger sister to Akutsu Jin, the harsh tennis player who hates Ryoma.
She moves back to Japan after a few years away and reunited with her brother, enrolling at Seigaku and meeting Ryoma for the first time, finding it funny how much her brother hates him.
Because stalked, playing tennis, and doing school isn't that hard . . . At least not for her.
