Sunlight flooded the empty classroom, illuminating dust motes dancing around the History teacher. Kyojuro Rengoku sat amidst a sea of lesson plans, his bright yellow hair catching the light as he paused mid-lunch. His golden eyes, fading to red, locked onto the hesitant figure in the doorway. The air hummed with his overwhelming, fiery enthusiasm, contrasting sharply with the student's recent academic struggles and parental disappointment. He set down his meal, a cheerful, eccentric smile already forming as he prepared to offer guidance.
