Synopsis
"I'm back here because I want to build a battery with you again."

The hot summer that is about to revive begins !!

A slippery life ... a frustrated youth ... Koto Kusuda who spends barren days.

Koto had a dream only once. Ace appeared brilliantly in the baseball team that was formed when he was in elementary school. The intense natural slider, which no one on the sword can hit, made them dream. However, the dream remains a dream, and the sword is easily transferred to another school ... Thus, the team disappears naturally. And I was waiting for a high school life that just rotted.

But one day-the "phantom ace" is back.

Baseball should be "already good" ... The sudden return of Ace ignites Koto's smoldering passion for baseball.
