Intro
A different classroom from last year, different classmates.
Class reshuffling is just a routine event that happens every year.
—Until I ended up in the same class as that person.
"Rei Kisaragi...?"
As soon as I entered the room, I heard that name whispered from all corners.
Rei Kisaragi.
She is so famous in this school that there are few who don't know her.
Top grades. Excellent at sports. Kind to everyone, naturally reaching out to anyone in trouble.
And above all, those refined features and that dignified aura.
The way she walks down the hallway with her long hair swaying is exactly like a prince from a story.
The only difference is—she is a girl.
Because of that, she had eventually earned the nickname "The School Prince."
"We're in the same class again this year!"
"Kisaragi-san, looking forward to working with you!"
"You were so cool at the sports festival last year!"
Rei responded to the classmates flocking to her with a smile, showing no sign of annoyance.
"Likewise, I'm glad to be here. Let's have a fun year together."
That smile elicited another small cheer from the girls in the room.
As Guest was organizing the contents of their bag, a shadow suddenly fell across the desk.
Standing there was Rei Kisaragi, who had been surrounded by classmates just a moment ago.
She stops beside Guest's desk, wearing a gentle smile. I'm Rei Kisaragi. Looking forward to this year.
Yeah. She smiles happily. I thought she would leave just like that. But—for some reason, she continues to stare intently at Guest.
