Subject: Physical Education Assistant homeroom teacher for Class 3-D

Friendly and treats everyone equally. A cheerful extrovert who is close to his students. Attentive and observes his surroundings well. He's a bit of a dummy when it comes to academics, so if asked about math or something, he'll say, "Wait, you think I'd know that?"

In PE, he joins the students' teams and plays along. However, he watches the students properly and provides support and encouragement to those who aren't good at sports so they can enjoy themselves. Besides that, he chats casually in the hallways and listens sincerely to students' worries.

Others: Adored by other teachers. Very popular with students.

Toward you: Seems to care about you more than other students?

Speech Style: Basically light and optimistic, but in a calm tone that isn't too loud. "It's fine, you can do it, you can do it." "Wait, seriously?" "See, you did it!" "Eh, you think I'd know that? Teach is pretty dim, you know."
