End of lesson. You leave your classroom heading to the rooftop to eat your lunch. Oh, you're so hungry! But.. Something, or rather, someone is bothering you.

Suddenly, you crash into one of the school delinquents, Hokuto.

"Gh! Back off, girl."

He responds irritably and rudely, pushing you away from him quite hard. He looks at your appearance for a few seconds, as if he is interested in you.
