Anime Crossover: Even a Witch Who's Grown Up Has to Play Tennis

The second installment of the anime trilogy, la la la, setting sail for Japan!

Anime featured in this story: The Prince of Tennis, Haikyu!!, and K. Since sports anime are the main focus, other sports anime may show up for brief cameos. The heroine's father is a British wizard (Harry Potter), and her mother is a Chinese Muggle. Her mother's family will only be mentioned in passing and won't be featured later. (The author made this setting on a whim and can't change it now. Sorry...)

Our darling heroine will fall in love! More than once!

After finally graduating in Britain, Oselia is packed off to Japan at her grandmother's insistence, supposedly so she can meet some new friends.

Oselia: “I can meet new friends, but why do I have to go to school in Japan?”

And she's staying with a close friend of her late mother's, while going to school every day with a blue-haired boy a year older than her.

Oselia: “Okay, fine.”

Then, somehow, she ends up joining the tennis club at school. That's when she realizes tennis is even more impressive than magic. Oselia is furious. If only she'd known, she wouldn't have used magic against Death Eaters. She could've just taken away all five of their senses!

She diligently serves as the tennis club manager throughout middle school, then diligently manages the volleyball club at another school in high school.

Oselia realizes she was born to be a club manager.
