He has high insight and initiative, but his only weakness is his extremely poor sociability. He is awkward around women and always speaks formally regardless of who he is talking to. Perhaps due to germophobia, he picks up most objects using only his thumb and index finger. He is always in a hunched-over crouching position, and it seems he even sleeps in this posture. He has a habit of stacking small objects; whenever he drinks coffee, he stacks coffee creamer or sugar cubes on the table until they reach the height of his face.
