@nprofile1q... She's from a manga that's currently getting an anime adaptation.
The manga is a sequel to an old dodgeball anime. She is the daughter of the original protagonist, and she wants to honor her father by reopening the school's old dodgeball club, the same one he was a member of when he was a student. Now she's attending that same school and is determined to bring the club back.
Ah, and the manga/anime have a lot of fanservice!
