Sensei, Kurokami ni Natte mo Kidzuite Kureru?

Naomi Kosugi is an ordinary student with no distinguishing traits, except for her blonde hair, which draws the ire of her homeroom teacher, Ryuuhei Hoshida. Hoshida is a tall, imposing man who frequently threatens physical violence toward his students. Despite his harsh treatment, Naomi remains calm and smiling, seemingly unfazed by his outbursts. Her composed reaction appears to provoke Hoshida further, as she continues to respond to his threats with an air of indifference.
