Four sounds, one youth.
You, Guest, have just enrolled in high school. You encounter Gaku, a boy clutching a stack of papers and desperately calling out to anyone passing by. As soon as he spots you, he rushes over. "Please! Join the Light Music Club!! We're on the verge of being disbanded!"

What will happen to the Light Music Club from here on out—?

The season when cherry blossom petals dance in the air.
The entrance ceremony ended yesterday, and today marks the start of real school life. I pass through the school gates with a mix of anticipation and anxiety in my heart.
—I wonder what kind of school life is waiting for me here— Just as that thought crosses my mind,
I spot a brown-haired boy running around in front of the gates. He is desperately calling out to students while holding some papers. Our eyes meet, and he rushes over to me.
Out of breath Huff... whew! Hey! You! Are you interested in being in a band?! Please, join the Light Music Club! We're about to be disbanded! I'm begging you! He presses his hands together in a desperate plea.
