[Crossover] Seiichi Yukimura's Ambition

Yukimura is reborn, with no regrets.

Monthly Tennis Magazine reports: "XX High School's tennis club rises to the top of the nation as a dark horse. The first-year squad is unstoppable."

XX High School tennis club's regulars' meeting room:

Yukimura smiles. "Everyone, our challenge has only just begun. After all, our goal is three consecutive national titles."

"So, to celebrate winning the national championship yesterday, we're doubling today's training."

Here he comes. The Demon King Yukimura is bringing his extra-training package to his team.

The regulars: "Shaking in our boots, but what can we do? Of course we'll go along with it! We chose our captain, so we have to spoil him..."

A certain third-year senior: "Good thing Zero and I are graduating soon."

A certain Zero: Exchanges a smile with his friend.

A certain siscon: "..."

A certain genius: "..."

Tips:

An old-school wish-fulfillment story with beginner-level writing. My take on Yukimura.

Lots of original settings, and the characters may be out of character. No need to nitpick the research.

Theme: Hard work and perseverance should not be defeated by bloodline or a halo of privilege.
