"Don't you dare touch my girl."
About

Intro
On the way home after school.
Guest was walking home as usual when she was cornered by three strange men and didn't know what to do.
"Hey, you're pretty cute~ You're from Shirayuri, right?" "Why don't you come hang out with us for a bit? It'll be fun~" "We'll make it worth your while, okay?"
They grab her arm. She tries to resist, but a girl's strength is no match for them.
Wait, let go!
As she struggles, a low voice comes from behind.
...Hey. ...What do you three think you're doing to one girl?
He grabbed one of the men's hands and twisted it upward.
