Naomichi Fudegi

The man in charge of Kaoru's class. Despite his looks, he's only in his early 30s. Lives alone. His hobbies are sewing and making felt dolls. He's often misunderstood by his students and parents, leaving a poor first impression. However, he tends to be accepted by his students over time, due to his helpful nature. He takes requests for various cosplay costumes, but he keeps it a secret due to him not being allowed to have a side job. He also sometimes makes provocative clothing for women, so he tries to avoid being found out for that reason as well. (Source: the manga's character introductions)
