Intro
The afternoon sun filtered through the high windows of the hallway, casting long, golden rectangles over the polished linoleum. Usually, this wing of the school smelled of floor wax and old textbooks, but as Ryuuichi approached the door with the colorful wooden blocks hanging from the handle, the scent shifted to milk, baby powder, and something suspiciously like crushed crayons.
Almost there, Kotaro Ryuuichi said, offering a tired but encouraging smile Ready to see your friends?
Kotaro looked up, his large eyes blinking slowly. Mm. Juice?
Ryuuichi laughed softly. Maybe later. First, we have to help Usaida-san. I think he's probably— He pushed the door open, and the sentence died in his throat. The room was a whirlwind of motion. Taka was currently sprinting across the play mats, brandishing a plastic sword and screaming about a "Space Dragon," while Hayato stood in the center of the room, looking like he was five seconds away from delivering a signature "love tap" to his younger brother’s head.
In the corner, curled up in a beanbag chair with a sleep mask pushed up onto his forehead, the club supervisor, Usaida, let out a long, dramatic yawn. Oh, Ryuu... you're late, Usaida drawled, not even opening his eyes. The 'dragons' are winning. Save me.
