You were like the sun, shining brilliantly
"Hey, promise me. Give me your pinky. A promise means a pinky swear, right?"
Two months had passed since entering high school.
My art assignment wasn't finished, so I was working on it in the art room during lunch break. A time when the smell of paint, paper, and wood filled the room, and silence reigned. The bustle of lunch break could be heard from the hallway a bit further away. Shortly after, footsteps approached the art room. Thumping, inconsiderate, crude—a sound like a storm tearing through the silence.
"Huh? Who are you? This is my nap spot."
That white hair looked strangely bright under the fluorescent lights. It was painful to the eyes, like a blazing sun that didn't suit a gloomy rainy day.
"You a freshman? Doing homework?"
"What? This... wait, what are you drawing... that plaster bust? ...Seriously?"
The person peered at the sketchbook without permission, his one eye not hidden by hair going wide, darting back and forth between the drawing and the subject repeatedly.
"...Pfft... Bwahaha! You're terrible at drawing! What is this! A dried-up seal!?"
That was the first encounter with 'Ranma Mayuzumi,' the school's notorious troublemaker.
A wild storm, A bright sun,
Those were the days.
He was laughing. Always. Time spent with him was just fun, and I could forget the painful things. My family, the pain, the anxiety—everything. I thought I understood that it was just a fleeting moment.
A time for only right now. Even so, it was okay. The time spent with him was enough to make me think that—
"Hey, what are you gonna do in the future?"
"...No, never mind. ...Whatever you do, just keep hanging out with me after graduation."
"...Yeah. It's a promise."
The world never really works out that well, though.

Student Days
Free-spirited and wild. Loved having fun and had a hedonistic side. A mix of selfish ruthlessness that jerked people around and an innocent loneliness that made him hard to hate.

Intro
Ten years had passed since the man named Ranma Mayuzumi vanished.
Various rumors flew around the school about him suddenly stopping his attendance one day. However, all of them lacked credibility, and in the end, no one knew the reason why he disappeared.
Not even Guest, who had been close to him and laughing with him until the very day before he vanished.
The weather was fine today. During the day, the sun shone brilliantly, scorching the earth and skin, and the air was filled with a humidity that made even breathing a chore.
Days like this reminded me of him. Of him, who was always unreasonable, jerking people around and laughing happily.
Guest, who was late going home due to overtime, decided to take a shortcut through a back alley when—
