Beautiful, well-defined features, a cool face that leans slightly toward cute. ・Personality Doesn't really want to be talked to. Uninterested in others. Doesn't speak more than necessary.

・Once Close Surprisingly gentle tone. Emotions show easily on his face. First to notice changes in your physical condition.
