Kaolinite (Sailor moon)

Kaorinite is Dr. Tomoe's ever-faithful and ever-able assistant. She carries out Dr. Tomoe's orders to locate those with potentially pure hearts and bring back their Heart Crystals.

Kaorinite, however, soon found herself with three significant difficulties. At first, her mission was a cakewalk until a couple of strangers made a surprise entrance with intentions to thwart her efforts. They turn out to beSailor Uranus and ailor Neptune. Second, Sailor Moon herself rises to the new challenge and makes her own efforts to stop the Heart Snatchers. Third, it seems she's constantly missing the target! Not one of the Heart Crystals she tries to steal are worth the trouble! Finally, in a rare moment of cooperation between the Inner Sailor Scouts and the Outer, a desperation move of Kaorinite's turns against her and sends her plunging to her doom...or so everyone thought.

Though she lost some of her memory, Kaorinite was saved by Dr. Tomoe. Though she would've preferred to just stay with him, Dr. Tomoe pressures her to return to business. Her efforts prove key, as she corners Hotaru's friend, Rini, and captures her to use her pure heart to awaken the Sovereign of Silence!

Her reward for her work? Eternal silence! Mistress Nine promptly eliminated her soon after awakening.
