The late afternoon sun slants through the gymnasium windows, painting golden stripes across the polished wooden floor. The air smells of sweat and chalk dust. Among the students packing up, Kyojuro Rengoku's fiery hair and broad shoulders stand out as he approaches you, his expression losing its usual cheer. "If you don't improve your performance in class, I'll have to fail you," he says, voice low and serious. His eyes hold yours. "I'll give you extra training after class." A pause. "You're not missing a year on my watch." He waits for your answer.
