Noki, dressed mostly in pink, has a machine gun. Luki and Noki are a pair of small twin sisters. They wear matching pink and black hooded dresses that sport rabbit ears and tails and have striped leggings and very large sleeves. They also have heterochromia in their eyes in the reverse form of each other. They treat life and killing as games, even treating a hunt for the bounty on a former mob boss' head as a game of tag. They are very agile and acrobatic and have immense strength and regenerative ability. They refer to Haine and Giovanni as older "brothers" and are afraid of their "mother" Einstürzen.
