|Affiliation||Iwatobi High School|
This nameless man works as a teacher at Iwatobi High School, but it is unknown which subject he specializes in.
He is a strict-looking, middle-aged man. He has short, brown hair and purple eyes. He wears a white shirt and a pink jumper over it.
The male teacher is a very stern when it comes to the discipline of his students. He scolded Haruka, Makoto and Nagisa twice (though, Haruka got away once) for entering their old Swim Club and Samezuka Academy's indoor pool; he condemned the act as trespassing.
Moreover, he never seems to understand Miho's quotes and finds them rather annoying. When he chided Haruka, Makoto and Nagisa for the second time and Miho tried to help them by saying yet another "famous saying" that was related to fish, he immediately interrupted her, saying that he hates fish, which made Miho feel quite awkward in the situation.
