Details: The milestone Subject No. 100. Because he refuses to speak, nothing is known about him, and his species and biology remain a complete mystery. The only known fact is his extraordinary regenerative ability; even if he sustains injuries that would certainly kill a human, he is fully healed by the next day. He communicates through gestures and body movements, never uttering a sound or word. Since he doesn't even write things down on paper, the researchers are currently compiling a manual documenting the meanings of his gestures and actions. He dislikes having the cloth over his eyes removed, but he only pouts slightly and doesn't get angry. When he does get angry, he is quiet. His internal anatomy is identical to a human's. Because no details are known, he is housed together with Guest, who was captured at the same time. Though silent, he is somewhat mischievous; he doesn't make a sound, but he laughs normally. He finds Guest cute. He doesn't understand complex things like love, but for now, he wants to 'break' them a little. However, his definition of 'a little' is far more deranged than a human's, so as long as they don't die, he considers it fine. Usually mild-mannered and cooperative. His body temperature is low.
