Kaolinite (SMCU)

Kaolinite (formerly Kaori Kuromine) is the Five Witches’ secretary, the Magus of the Death Busters, and the principal of the Infinite Academy. She formerly works for Professor Souichi Tomoe.

Appearance
She has long red hair, and wears a black dress with a black pendant around her neck. As Kaori, she wears a red dress.

Prior to the Cinematic Universe
Kaori first met Professor Souichi Tomoe in Russia in 2007 along with young Russian astronaut Ilya Chernozvezdova. At the same year, she became the principal of the Infinite Academy in 2007. As principal, she began passing educational decrees for the Academy.

In the year 2012, Kaolinite encountered Pharaoh 90 from the Tau Star System after being struck by a bolt of lightning during a chaotic storm. She sold her soul to Pharaoh 90, becoming the "Magus" of the Death Busters. The privileges of the Magus position include the use of the Tau Star System's crystal and direct contact with Pharaoh 90.

As a member of the Death Busters
In the post-credits scene of Tuxedo Mask: The Last Starlight, Kaolinite discovers Black Moon Clan member Esmeraude at a Jacuzzi in New York City and took her in as her co-secretary. Esmeraude would later be killed by Mimete, one of the Five Witches, while she was committing suicide in Jupiter’s Quest: The Four Crusaders.

In Flame Sniper: Fire Soul Bird, Kaolinite operates the Death Busters from an undersea base. She and her assistant Esmeraude survived when the base was destroyed by a Japanese Defense Force submarine.

Sailor Moon Twin
Kaolinite continues to create even more educational decrees, this time to further control Infinite Academy’s students.

Kaolinite later becomes the invigilator for a midnight examination during the Battle of the Seven Sailor Moons, which happened in the vicinity of the Infinite Academy. Kaolinite is chased to the elevator by the Moon Worldshaking Dragon sent out by Sailors Jupiter and Uranus (disguised as Sailor Moon); destroying the Educational Decrees she had created in the process.

While fleeing to her office in the top floor of the Infinite Academy building, Kaolinite knocks out Sailor Chibi Moon and held her captive before being encountered by Sailor Moon and her twin Serena. Thanks to their superb self-defence skills, Sailor Moon, Sailor Chibi Moon and Serena manage to overpower Kaolinite until she is left clinging over the edge of a broken window. Sailor Moon attempted to pull her up, but she took a shard of broken glass and tried to stab her, injuring Sailor Moon in the process. Sailor Moon then let go, sending Kaolinite falling to her death.
