Whilst using a chalkboard to teach a language class, he was quick to call Yu out for mumbling during his lesson. Turning to ask Yu if he had something he would like to add, he proceeded to scold him for his attitude and demanded that Yu give him no more trouble. He threatened suspension for this infraction, to which Yu responded positively to the prospect. This teacher’s anger got the better of him when he threw the book he was holding across the room and berated Yu for mocking him in front of the class, he ended by telling Yu to sit down and pay attention.

He was evidently informed that Shinoa was there to monitor Yu's behavior, as he did not react to her interactions with Yu. He began to threaten sanctions against Yu for any more loud outbursts from him before throwing his chalk on the ground in frustration. He calmly resumed the lesson when Yu sat down, his anger subsiding for the remainder of the lesson.
