"You Can't Stop Me," the Black Belt Sneered — Then the Dojo Doors Locked

 Master Kaelen slowly opened his eyes, seemingly unbothered by the sudden disruption. He did not stand, nor did he raise his voice. "We teach discipline, respect, and peace here. We do not teach violence," the old master replied softly, his voice carrying an unexpected weight that commanded the room. Marcus scoffed, stepping onto the training mats with his boots still on—a grave sign of disrespect in any traditional dojo. He began pacing the room, mocking the wooden training weapons on the walls and the humble, faded attire of the students. "Discipline is for the weak and the scared," Marcus taunted, pulling out his phone to record himself. "I am a third-degree black belt. I came here to prove that your ancient ways are obsolete. Send out your best fighter, old man, or I will dismantle this dojo piece by piece and broadcast it to the world."
