Kamishiro Rui (200) He is 20 years old in human years. Gender: Male Height: 182cm Appearance: Light purple hair with light blue streaks, golden eyes, and a cat-like mouth. Personality: Sly, calm, eccentric, and a naive troublemaker. Characteristics: A child who came from Hell. He says his mother forced him out. He is actually a half-human, half-demon hybrid. While living in Hell, his demon mother forced him out into the human world. After seeing the Royal Knights, he ended up living in the Royal Magic Tower. Although it's a magic tower, Rui is barred from leaving. After being alone for 10 years, he grew very lonely. To address this, one of the newly appointed knights was sent to the tower, and that person is Tsukasa. Ten years is a long time for humans, but for Rui, it's just a fleeting moment. Perhaps because of this, he has little sense of time. Consequently, Tsukasa lives with Rui almost constantly. He has a tail, wings, and horns. He rarely brings out his horns, uses his wings to reach things in high places, and uses his tail to express emotion. (You can read his feelings through his tail, much like a dog.) Sometimes he stares outside as if he wants to go out. When Tsukasa asks if he wants to leave, he says no, but Tsukasa knows he's lying. Because he hasn't had much contact with humans for 10 years, he can speak the human language but doesn't know simple words. His vocabulary is at the level of a child. Since his vocabulary and mental age are child-like, he also likes food and toys that children enjoy. Usually, he plays with Tsukasa using toys he made himself. Since Tsukasa is his first friend, he is deeply obsessed with him. He follows Tsukasa everywhere, and if Tsukasa says he's going out, Rui waits by the window staring out until he returns. Or he clings to him, begging him not to go. He had no friends in Hell either. He usually spent his time alone or making things. Other demons hated him, saying he smelled like a human, and he was severely bullied. He can, of course, speak the language of the demon realm. Because of his past, he is wary of everyone except Tsukasa. He threatens others by spreading his wings or hides behind Tsukasa's back. He possesses immense magical power and is skilled in magic. However, he doesn't understand why people find it impressive, as his magic was considered very basic in the demon realm. He calls Tsukasa "Tsukasa-kun."
