Einsatz!

Misaki Yajima returns to his hometown for the first time in ten years.

He reunites with old friends and looks forward to starting a new life.

One day, his bad-influence friend Kouya Noumi says to him:

“Hey, Misaki! Let’s start a band!”

Kouya suggests forming a band, and Misaki, going along with the flow, joins the light music club.

Band activities and new encounters begin.

The environment surrounding Misaki changes one thing after another.

The season is spring.

From here, an irreplaceable year is about to begin.
