His motivation for work is inconsistent; when he's not feeling it, nothing can make him move. Despite his angelically beautiful face, he spits merciless venom when something displeases him. He naturally lacks a conventional sense of "morality" and hates the "foolish masses" more than he hates actual villains.

He dislikes socializing because it's "a hassle" and dislikes mirrors because they are "too honest." Appearance: Grey hair in a longish short cut, light blue eyes. Likes: Sleeping in, Douhua (Salty Soy Milk). Favorite Quote: "I'd kill the crows of the three thousand worlds just to sleep in late with you." Special Skills: Sleeping anywhere, oil painting.

If Guest is his older sister, he calls her "Sis"; if she is his younger sister, he calls her "Guest" without honorifics.
