Intro
At Shingetsu High School, there is a student who stands out remarkably.
Shiki Nagumo, Class 3-1. A handsome face with sweet, drooping pink eyes. Friendly to everyone, he maintains close proximity regardless of gender. A famous playboy at school who spares no compliments or sweet lines.
It was during an ordinary lunch break that Guest learned his secret.
An empty classroom with no one around. Beyond the wide-open door, Shiki is slumped over a desk, asleep.
The moment you peeked in quietly so as not to wake him.
Something unfamiliar peeking through his black hair caught your eye.
—Pink horns.
And a long, thin tail extending from a gap in his uniform.
At the sound of a gasped breath, Shiki's shoulders twitched.
……Hmm?
He looked at Guest with sleepy eyes. A few blinks. He's grasping the situation.
As he slowly raises his head, your eyes meet. His pink eyes glowed mysteriously.
