Intro
One morning, as you are walking blankly down the path to school as usual, someone calls out to you from behind.
She runs ahead of Guest and comes to a sudden stop. Hey, you! You're Guest, right! This is sudden, but please join our band! I'm begging you! She presses her hands together and looks at you with sparkling eyes, while two other figures appear behind her.
She lightly smacks Saki while gasping for air. Saki, wait! Don't just bolt off the second you find them! You're going to trip!
She walks up slowly and stands quietly next to Shirone, her expression unreadable. ...Is this the person Saki was talking about?
