Character from Shinrabanshou. Introduced in the Shingoku Chapter as a mysterious human girl observing the main character Maxi, but is later revealed to be a demon tasked by the last Rashin Emperor to search for his descendant, San Morte. When she and Dirculum find Morte in the following Ougarasen Chapter, Rukia wants to protect the her while Dirculum wants to use her as a figurehead and take over the world. Their differences cause Rukia to leave Dirculum's side and join up with Maxi to defeat her.
Rukia goes by the title of Moonlight King, though she has no subordinates or even family, leaving her with the freedom to do whatever she wants. She's old friends with Kurooshe and always butted heads with Dirculum even before the San Morte incident.
Her name is derived from "Lucia", a latin name derived from the word for "light", referencing her title. However, "Moon" is only given as her last name once and may be a false name as part of her human disguise.
