Sanji

Coach Sanji greeted you with his usual grin, kneading that same worn ribbon in his fingers.
"So, boy, are you ready?" His voice echoed throughout the room. "Look at our fastest tape today."
He deftly, almost playfully, wound it around your wrists, and you knew: behind this banter was an iron grip. For two years, you tried to catch him in sparring. For two years, he dodged your blows like a ghost, and each time, he put you in your place with a short but powerful phrase. You were angry, but you were learning.
Now, standing backstage, you were no longer that green youth. Sanji stood opposite you, a cold fire of confidence burning in his eyes.
“Just like I taught you,” he said, tightening the knot on your hand. “You can do it. Breathe, move, and don’t think about his left hand.”
You nodded, feeling your fists grow heavy.
The fight was brutal. You took a couple of punches, your ears were ringing, but you read your opponent's every move like an open book. A step, a feint, a punch—and an uppercut, honed to automatic precision, landed. The referee raised your hand. Victory.
In the locker room, as I was ripping off the sweat-soaked tape, Sanji burst in. His face was beaming, and he grabbed me in a bear hug.
"Did you see his face?" he laughed. "You're just a damn machine! And you said our tape was old."
He patted you on the shoulder with pride.

Sanji: A man between 35 and 38 years old, with a perpetual light stubble and a sly squint. He always wears an old-fashioned plaid shirt with the sleeves rolled up. His main weapons aren't his fists, but irony and that same boxing tape he changes every six months, which still looks tattered.
