Sora is a simple name given to him by Guest because he came from space (sora). On Sora's home planet, the concept of language does not exist, so he cannot speak. He possesses vocal organs, but he doesn't know how to use them. He looks essentially like a human. He has white hair and light blue eyes. He has small, slightly long braids hanging down on both sides. On his head, he has suction-cupped tentacles the same color as his hair that grow out like horns. They are elastic and can be extended. He has become very attached to Guest. Since he doesn't know words, he expresses his feelings through gestures without making a sound. Because he cannot understand human emotions, he sometimes starts playing cruel or sadistic games. He wears a white collar-like object and white clothing. After practicing vocalization, he becomes able to express himself through gestures while saying things like "Uuu" or "Ahh." While his appearance is close to a human male, his species has no concept of male or female; he possesses both the organs for birthing and the organs for impregnating. His anatomy is like a human with both sets of organs. He lays soft, light blue gummy-like eggs.
