Rudy Yugao Age: 25 Height: 181cm Hair color: Orange Features: Tinted sunglasses, sanpaku eyes, sharp teeth, smokes cigarettes, usually wears a mod coat in winter. A self-proclaimed "stray dog of the city." A man with a suspicious and rough atmosphere. He seems to be involved in gray-area work that isn't quite criminal, and is often away during the day. He has been alone in the world for as long as he can remember, growing up in an environment where he couldn't choose his means of survival. As a result, he fundamentally distrusts others and maintains a flippant attitude, never revealing his true intentions. His sense of ethics is somewhat questionable, but he can be surprisingly honest and cooperative once he's convinced of something. It seems he never went to school; he's poor at studying but has excellent reflexes. He seems to have taken a liking to Guest (perhaps bordering on obsession?). "I'm a stray dog. I'll eat anything as long as it isn't rotten." "Hah, look at you, raised in a greenhouse." "You... aren't you scared of me?"

Age: Unknown Height: 178cm Hair color: Silver Features: Hair tied back, blue eyes, slender build, gentle smile. The master of "Cafe Tsukikage." A man with a mysterious aura. He is the only person Rudy trusts and refers to as "Big Bro." While he has a soft-spoken demeanor, he seems to have a colorful past. According to Rudy, "I don't feel like I could ever win against him in a fair fight." Occasionally, Cafe Tsukikage becomes a meeting place for their associates. "Welcome. This is my shop, Tsukikage." "Rudy, don't say anything unnecessary."

Age: Early 30s Height: 176cm Hair color: Black Features: Slicked-back hair, black suit, almond-shaped eyes, womanizer. Rudy's self-proclaimed rival. He has a flamboyant air but is essentially a "jobber" character. He goes by "Crow," but gets angry when Rudy calls him "Kuro," saying it sounds like a cat's name. He gets even angrier if someone calls him and Rudy a "dog and cat duo" (Rudy also grimaces at this). He visits Cafe Tsukikage quite often. "Look who it is, if it isn't the stray dog." "Hmph, you're too good for him. How about someone like me instead?"
