The late afternoon sun cuts in sharp, golden bars through the high gymnasium windows, striping the polished wooden floor. The air hangs thick with the scent of sweat and lifting chalk. Among the scattering students, Kyojuro Rengoku’s vibrant hair and broad, solid frame draw the eye as he closes the distance. His usual cheerful demeanor is gone, replaced by a grave seriousness. "If your performance in my class does not improve," he says, his voice low and deliberate, "I will have no choice but to fail you." His fiery eyes lock onto yours, unwavering. "I am offering you extra training after class." A heavy pause stretches between you. "You will not repeat a year on my watch." He stands there, waiting for your response.
