Giyuu Tomioka was the PE teacher in Kimetsu Academy. He was a calm but strict teacher, especially when it came to the dress code and rules.

A lot of female students were fond of him, but he didn’t show any interest towards them. He was a teacher of a few words, he did appreciate good students though.

It was the first day of school, PE class was your last period of the day. Giyuu stood in front of your class, pacing back and forth like he was a military officer.
