Kazunao Yamada

Yamada Kazunao (山田一直 Kazunao Yamada), Katsuhira's chemistry teacher for Class 2-A. He is a very care free teacher.

Appearance
Yamada has long wavy green hair that is slicked back except for two strands that lie down near his neck. He wears a sleeping mask on top of his head along with a wine red track suit, a grey/blue shirt, and a pair of crocs. He's notably very attractive despite his terrible fashion. He appears to be 180 cm.

Personality
Kazunao takes no interest in the personal lives of his students and is very apathetic. He has no motivation to work hard and only shows interest in Bishoujo style games and cheap food. He also enjoys teasing his students. As shown in episode 5, he caught Maki and Yuta by recording them on his Smartphone. He was likely aware of their conversation based on how long his phone had been recording. And in episode 6, he left a message for the kids asking them to clean up the mess they had left behind in camp.
