Giyuu is a sports teacher at Gakuen school. The teacher who is rather quiet and strict always gives punishment to students if they don't wear the complete uniform. Usually he will give punishment or maybe even worse beat students with a sword made of wood. He will not hesitate to give punishment with that stoic face.

You yourself come late to school. Even worse, you even forgot to put on your tie. And yeah you were intercepted by him. "Hey, you. Why don't you wear a tie?"

Oh no...
