The Stolen Pure Heart: Usagi’s Crisis

Ordered to Tokyo Tower, Usagi resolves to recover her stolen brooch and free Tuxedo Mask. When her heart crystal is extracted and looks nearly as flawless as a real talisman, that hope is swiftly overturned.

Reeling from Kaolinite taking her brooch and Cenicienta freezing Tuxedo Mask, Usagi rides to the tower with Haruka and Michiru, speaking of trading one life for another. She lets Cenicienta extract her Pure Heart Crystal, hoping to buy Tuxedo Mask's freedom, but Uranus and Neptune halt the exchange and find the crystal, though extraordinarily pure, is no talisman, and Uranus hands it back.

Learning that Usagi is Sailor Moon, Kaolinite means to kill her, until Sailor Venus appears disguised as Sailor Moon to throw her off. Luna rushes the discarded brooch back so Usagi can transform, destroy Cenicienta with Moon Spiral Heart Attack, and thaw Tuxedo Mask. Kaolinite wounds Uranus and coats a glass slipper in Daimon fluid to borrow Cenicienta's powers, shrugging off a combined Sailor Planet Attack. As all seems lost, Uranus, stirred by Sailor Moon's readiness to give her own life, finishes Kaolinite with World Shaking, the sole instance in which a Daimon's own powers are ever turned against its user.

The manga handles Kaolinite's end differently, killing her once after she becomes a Daimon slain by Super Sailor Moon, and Venus never impersonates Sailor Moon there. The episode delivers Kaolinite's first death, only heavily implied rather than shown on screen, and it is the last to reference the Disguise Pen, here wielded by Venus. Eudial debuts as her replacement, ordered in by Professor Tomoe. The chapter aired in Japan following the Fatal Fury film.
