紅のルベウス

Crimson Rubeus is the first member of the Black Moon Clan to appear in the 20th century. He is charged with finding a person codenamed "Rabbit", who had fled into the Tokyo of the past. Besides following the orders of Prince Demand and Wiseman, he leads his own set of minions (the Ayakashi Sisters). In the anime, he is the love interest mainly to Cooan, the youngest of them, though the majority of the sisters are in love with him; only the eldest, Petz, doesn't have feelings for him. In the manga, he kidnaps Sailor Mars, Sailor Mercury, and Sailor Jupiter but fails to capture Sailor Venus. He is extremely loyal to Prince Demand, appearing with him to taunt the captured Sailor Moon.
