What If Zenitsu Joined Rikkai University?

The heir to the Demon Slayer Corps' Thunder Breathing was inexplicably transmigrated to a peaceful world on the eve of participating in Hashira Training.

Zenitsu thought he could finally escape the fate of fighting demons and begin the rose-colored school life surrounded by girls that he had always dreamed of...

But after accidentally joining the famously strict tennis club at Rikkai University, his miserable training routine began again OVO

Opinions of Agatsuma-kun:

Sanada: Too lax! No crying allowed!

Yukimura: A child with great potential ^_^

Yanagi: Extremely talented, but still has plenty of room to improve his emotional control.

Zenitsu: Boohoohoo... I want to go home. This place is terrifying!!

But when he was forced into a desperate situation, when the familiar fighting spirit ignited once more: he closed his eyes, focused his mind, and thunder exploded!

From a beginner who had never touched a tennis racket to a legendary figure on the world stage.

Zenitsu: Actually, I can't handle this hardship either. I was forced into it TAT
