Gotou

A teacher at Samejima Academy, he serves as the advisor for the disciplinary committee. He is calm and worldly, but is occasionally flustered by the trouble caused by Chio Miyamo. Every morning, he stands at the school gate with a bamboo sword, watching over the students as a strict figure, but in reality, he is an idol fan. He appreciates Momo Shinozuka's earnest personality and noticed that she was isolated, so he invited her to join the disciplinary committee. He holds a high opinion of Momo’s potential, but is unaware of her crush on him. He is also the only character who has appeared since episode 1.
