Catzi is a major character in Sailor Moon series, and is the third of the Ayakashi Sisters who serve under Rubeus.
Catzi was with Rubeus in the guise of an academy student to recruit through the Black Moon supernatural club she set up. After setting a fortune telling booth where she predicts the time of her client's death, Catzi is confronted by Sailor Mercury as the two proceed to fight. But Catzi captures Sailor Mercury before being destroyed by Sailor Moon.
Having romantic feelings for Rubeus, Catzi worked to capture Chibiusa before she was abandoned by her superior to die at the Sailor Guardians' hands. But Sailor Moon purifies Catzi to live a normal life in 20th century Tokyo, opening a cosmetic shop and later helping in her sisters' purification as well.
