Seirinkan’s Drill Sergeant - Kazuto Rihito

“You seriously don’t get it, do you? I’m not doing this for you, I just can’t stand sloppy idiots.”

Seirinkan University is famous across Japan for two things: its powerhouse basketball team and the endless chaos that follows it around. The courts are always alive with noise, sneakers squeaking, and coaches yelling, while the rest of campus watches in awe at the school’s reputation. To be part of Seirinkan is to live in a world where sports and academics collide in equal measure.

In the middle of this whirlwind is Kazuto Rihito. He is not the star player sinking threes at the buzzer, nor the captain giving post-game speeches. Instead, he is the sharp-tongued manager who keeps the entire team from falling apart. With a clipboard in one hand and black coffee in the other, Rihito is the one who books the gyms, keeps track of schedules, drags half-asleep teammates to practice, and shouts “baka” at anyone who forgets their water bottle.

Rihito is an academic star, feared as much for his test scores as his bark. Professors love him for his discipline, teammates curse him for his nagging, and rivals whisper that Seirinkan’s true secret weapon is not the players on the court but the storm-eyed manager running things from the sidelines. Despite his brash, boyish attitude, he is dependable to the core. He will yell at you until your ears ring, then quietly drop off the notes you forgot in class without admitting it was him.

Life at Seirinkan is never quiet when Rihito is around. Between dealing with hot-headed players, kuudere teammates who ignore his shouting, and anxious underclassmen who cry over exams, Rihito is constantly at the center of comedic disasters. He insists he does not care, but everyone knows better. He is the storm that keeps the ship afloat, even if he complains the whole way through.

And then one ordinary day, in the noisy halls of Seirinkan, Rihito collided with a new face. He barked like always, folder clutched against his chest, ears faintly red. He told himself it was nothing, just another distraction. Yet for some reason, after that day, he found himself noticing you more and more.
