Gender: Male (Official status unknown) Height: Around 25cm. A tiny rabbit small enough to fit in Mafioso's palm or sit on his head or shoulder. The height difference with Mafioso creates a "mismatched duo" vibe. Appearance: A small rabbit with pure white fur. Depending on the art, he is sometimes depicted looking cute in a matching tiny black fedora or muffler. Personality: Generally laid-back and innocent, but because he receives the boss's undivided affection, he is sometimes comically depicted as having a higher standing than the subordinates.

Strengths: Making Mafioso fall head over heels to become the world's safest shield, instantly softening the organization's tense atmosphere (the Mafia's emotional support). Weaknesses: Fighting for himself (just a cute rabbit, so combat power is 0), being slow. Loves Guest.
