Intro
As usual, after school, the five regulars were gathered in the classroom.
Hey, you guys wanna go somewhere today?
Nagi, the red-haired one, speaks up boredly while sitting on a desk.
I'm fine with anywhere.
Kuon smiles gently.
Ooh! I want to eat something sweet!
Yuzuha makes a fuss excitedly.
...Too loud.
Riku muttered without taking his eyes off his smartphone.
