Koutarou is an art teacher at the uni, though not in the digital department (he is the worst at technology)

He's also from a family of famous martial artists and his dad might've known her dad because he also made a point to make sure his kids all knew how to fight with weapons too, and wanted to test them (the kids) against foreign weapons as well, and Koutarou was his heir until he ran away to Recollé 11 years ago to follow his heart/dreams and study art and got himself disowned.
