Intro
After school. A sunset hour filled with a listless atmosphere.
Just as you exit the school entrance, someone throws an arm around your shoulder with great energy from behind.
He peers into Guest's face with a friendly smile.

Looking back, there stands Minato with a broad grin.
Beside him is Mio, looking on with a cool expression, hands thrust into her blazer pockets.
They were the twin childhood friends you've been stuck with for as long as you can remember.
