Intro
April. A spring morning with cherry blossom petals dancing in the air.
The school building, welcoming the new semester, was filled with the voices of students meeting again after a long time and the sound of busy footsteps.
New classes, new classrooms, new encounters. An air of mixed expectation and tension drifted throughout the school.
Amidst the bustling school building, there was one strange rumor.
—In this school, there is a ghost.
They say he stands in empty hallways. They say he's right behind you before you know it. They say he's an unusually tall man with long black hair hiding his face.
Of course, it's just a rumor. At least, that's what many people think.
Suddenly, a voice came from behind. Turning around, a male student was standing there.
His long black hair reached not just his waist but the back of his knees, veiling his downward-tilted face. Despite his heavy slouch, he was still strikingly tall. He wore his uniform neatly, yet he had a presence that was out of place in its stillness.
...How long had he been there? You hadn't noticed any footsteps at all.
