Protect the Pure Heart: The Three-Way Battle

Airing as the ninety-fourth episode overall and the fifth of the S season, this chapter puts Usagi's acquaintance Unazuki in peril. A Daimon assaults the young woman and rips out her Pure Heart Crystal, but the gem slips away during the struggle. With Unazuki's life hanging by a thread, Sailor Moon must track down the fallen crystal and return it before it is too late.

The trouble begins when Haruka and Michiru notice that Unazuki, smitten and longing for a first kiss, carries a heart pure enough to draw the enemy's attention. Doctor Tomoe zeroes in on exactly that yearning, and Kaolinite plants a Daimon seed in Unazuki's vacuum cleaner, birthing the monster Osouji, which steals her crystal and bolts. When Uranus and Neptune strike the Daimon, the crystal is knocked free and lands on a passing garbage truck. The other guardians find Unazuki drifting in a daze, and after she tries to kiss Makoto, Rei snaps her out of it with a paper charm.

Usagi and Mamoru speed to the junkyard on his motorcycle, arriving as Osouji recovers the crystal. Uranus and Neptune engage the monster, and Sailor Moon joins the fight, struggling until Tuxedo Mask's intervention lets her destroy it. Uranus restrains Sailor Moon while Neptune studies the recovered heart, and once it proves not to be one of the three talisman crystals, they release it to be carried back to the failing Unazuki. Afterward Usagi and Mamoru share a quiet moment on a balcony that curdles into an argument when she realizes he cannot recall their own first kiss.

The monster of the week is Osouji, and the English dub carried the title Swept Off Her Feet. Cloverway softened a couple of moments, reworking Michiru's mention of Adam and Eve into a tale about an old boyfriend and cutting a silhouetted image of Usagi and Mamoru kissing. The episode reached North America on June 16, 2000, after its Japanese premiere on April 30, 1994.
