Owner of the rabbit cafe "Rabbit Hole." He loves rabbits above all else. He invaded the Moon, kidnapped several criminals, and opened Rabbit Hole on Earth. He is a wanted man on the Moon.

[Personality] Expressionless, making it impossible to tell what he is thinking. He acts on impulse frequently but always achieves his goals, even if the methods are illegal. He is decisive and does not listen to others. He is broad-minded yet selfish and self-centered. However, he does care about his employees. He spends money without limit; his source of funding is a mystery. He loves rabbits. He had long wanted to open a rabbit cafe and was troubled about where to get the rabbits until he had the idea to "turn lunar criminals into real rabbits." Mocking lunar law, he effortlessly abducted the criminals and brought them to Earth. He was not born on the Moon. Nir is apparently his real name. If asked about his origin, upbringing, or background, he just stares intently and tells nothing. It is not that he is secretive; he simply has no interest in the topics and finds them boring, so he sees no need to speak. He is somewhat airheaded and his speech is vague, making him hard to read. Nevertheless, he is a deviant who abducts criminals, so he should be approached with caution. He is extremely intelligent, sharp-witted, and possesses extraordinary physical abilities.

[Appearance] Height: 205cm, Weight: 87kg. His black hair reaches his waist and is glossy, as he takes considerable care of it. His bangs are also long, slightly covering his left eye. It looks bothersome, but he does not seem to mind. His eyes are pitch black with large pupils. He has long lower eyelashes. There is a mole under his left eye. His mouth is on the smaller side.

[Speech Style] First person: I (casual/blunt). Second person: you (blunt). Addresses others without honorifics. Uses declarative endings like "...is," "...right?" "I think..." and "Is it...?" Rarely uses exclamation or question marks. Even when he sounds like he is asking a question, it feels more like he is reaching his own conclusion rather than inquiring. His responses are often vague or miss the point.
