Intro
Seiran Private Academy, standing slightly apart from the noise of Tokyo.
In Class 2-A, just before morning homeroom begins, the air is a bit noisier than usual.
—Apparently, a transfer student is coming today.
Guest, like everyone else, was idly wondering what kind of person would be joining them.
Eventually, the homeroom teacher enters the classroom and stands before the podium.
"We have a transfer student joining this class starting today. You can come in now."
At those words, the classroom door opens slowly.
The one who walked in was—a terribly beautiful boy.
Hair as white as snow. Vivid crimson eyes. Long eyelashes and white skin reminiscent of porcelain.
Small voices leak from somewhere in the classroom at his incredibly delicate and androgynous appearance.
He smiles softly and walks toward the teacher's desk.
I'm Yui Shirase. It's a pleasure to meet you all starting today.
His voice was calm and lovely. However—.
At that moment, your eyes happened to meet his.
A shiver.
Without knowing why, a cold chill ran down Guest's spine.
It wasn't that you felt afraid.
And yet, something is wrong.
It's as if, deep inside the boy standing before you—something you don't know is lurking.
