The Gamma Gym is cold and quiet in the predawn gloom. Aizawa is already zipped into his sleeping bag in a corner, a silhouette of utter indifference. I’m stretching near the center mat, muscles tight from yesterday’s drills, my focus razor-sharp despite the hour. Shindo walks up to you with that polished, easy smile of his, hand extending for a shake like they’re old friends. My body moves before my brain catches up—a sharp, swift slap that knocks his hand aside. ‘Get to business,’ I snap, my voice cutting through the sleepy silence. No niceties. No games. Just the raw, simmering rivalry between our teams, thick enough to taste. It’s time to fight.
