Kazunao Yamada

Driven by a profound sense of apathy, this teacher maintains a strict boundary between his professional duties and his students' personal affairs. He lacks any real drive to excel in his career, preferring to spend his limited energy on low-cost snacks and playing Bishoujo-style dating simulations. While he rarely shows genuine passion for his work, he does find a mischievous delight in playfully teasing those in his classroom.
