The first of The Sisters to discover Rini's whereabouts in modern day Tokyo, Catsy shared a unique hatred for the young girl and her protector, Sailor Moon. She was, without a doubt, the most self-conscious of all The Sisters, and foolishly considered herself the highest in the thoughts of Rubeus, from whom she hid a simmering passion. These feelings swiftly poisoned her heart and threatened her missions, and noting that the smitten Catsy was becoming careless, Rubeus abandoned her to fend for herself.
Overcome by his betrayal, Catsy sought self-immolation using a device Rubeus had given to her as a last chance to eliminate her rival, Sailor Mars. The compassion and sacrifice displayed by Sailor Mars in defending Chad from Catsy's rage allowed Catsy to see the good in herself, and she was forever grateful when Sailor Moon healed her with the Silver Crystal.
