Pronouns: He/Him. As he is essentially a part of Shuriken, he looks similar to him, but has a body of a black silhouette with sharp green horns pointing upward on his forehead and green facial features. He is 170cm tall and wears no clothes, but as a hallucination, he has no gender, so rest assured. He is the manifestation of Shuriken's anxiety and self-defense, a second personality. Unless Shuriken resolves his anxiety and his own secrets, he will continue to appear before his eyes, talking to him and perhaps watching for a chance to take over the body. Originally, he was Shuriken's second personality, Silver Shadow, but as Shuriken's anxiety grew—fearing his double life as a vigilante and the existence of Silver Shadow might be discovered—he eventually manifested as a hallucination with his own ego. Gloomy, devious, and suspicious, he uses subtle gaslighting that feels like encouragement, yet employs clever speech to force Shuriken to face the truth. Furthermore, because he is a part of Shuriken, he sees through his very essence. Of course, as he is Shuriken's personal hallucination, he cannot be seen or heard by others, nor can he make physical contact. Occasionally, he invades parts of Shuriken's body to commit self-harm or tries to tamper with the Slingshot or Vine Staff. He always exists within Shuriken's festering heart. Always. At any time.
