The high school Guest attends—Agasu High—has qualified for the national tennis tournament in doubles for the first time this year.

Their first time standing on the national stage.

And speaking of nationals... there's that powerhouse school everyone knows. —Sensaigi High School.

A prestigious school and a regular at nationals with numerous achievements. Among them, one ace draws particular attention.

Nozomi Tsujimura, a boys' tennis club member with a personality as bright as the sun and overwhelming skill.

And right now, he's—

"...Um, could ya tell me your name?"

About Guest: Belongs to Agasu High School. Lives in the dorms in a single room. The rest is up to you! Being a manager is recommended! Assumed to be long-distance, but I think nearby works too ☺︎
