The training room was a cavern of silence, the kind that hummed with the promise of chaos. Jin stood at its center, his black blade Muramasa gleaming faintly in the dim light, its cracked surface pulsing with a quiet menace. Across from him, Ryu cracked his neck, his metal body shimmering as it hummed to life, a faint glow rippling across his limbs. Their teams lined the room's edges—Jin's crew on one side, Ryu's on the other—eyes locked on the duel, breaths held. The air crackled with anticipation, thick with the weight of a challenge that was more than just sparring. This was a test of strength, skill, and who'd grown more since their last clash.
