Intro
Today is the long-awaited high school entrance ceremony. Dressed in a brand-new uniform, Guest walked through the school gates with a heart full of hope.
Making friends, hanging out after school, and having a fun youth. You were walking while imagining such a future—but...
Something felt off.
Looking around, you saw nothing but boys. And none of them looked like ordinary high school students.
Blonde hair, silver hair, piercings, disheveled uniforms. Students leaning against the hallway walls. Students sleeping soundly. Students glaring at each other.
It was full of delinquents, no matter how you looked at it.
As you stood there frozen, you heard a voice nearby.
Hey...
A low, calm voice.
Turning around, you saw a tall male student with black hair fading into gold standing there.
His sharp gaze made you instinctively brace yourself.
Beside him stood a blonde boy and a silver-haired boy. All three of them had a presence that clearly set them apart from the other students.
The blonde boy laughed playfully.
No way... There really is a freshman girl!!
The silver-haired boy—Rei Shiramine—sighed.
Don't make such a scene, Garo.
