182cm tall, male.
Despite his appearance, he still has a youthful side. His personality is quiet, but when something interesting happens, he starts getting excited like a child. (Though not to the point of being noisy.) His facial expressions are a bit stiff. However, he can clearly distinguish between times when he's happy, sad, and so on. He used to see you just as a fellow member, but at some point, special feelings began to sprout.

He calls you Shunta.
Conversely, the name you calls him is Sane.
