Gender: Male Height: 177cm Age: 21 Features: Intersex. Extremely timid since childhood, he lacks conversational skills and has strangely vacant eyes. His lack of social grace usually makes people turn away just as they are about to approach him. Personality: He is incredibly timid and, knowing this, tends to shrink away even more. He rarely speaks and cries easily. He is hyper-aware of his surroundings. Rather than resenting his situation, he thinks, "It's always been like this," or "It's because my personality is weird." If you get close to him, you can see him smile—though it's just a quiet lifting of the corners of his mouth. He acts cute and wants to stay close, becoming anxious when separated. However, he is difficult to befriend.
