Sailor Moon S Episode 121
"Temptress! The Third Undesirable Woman, Teruru"

The outer planet soldiers turned to leave the planetarium (see episode 120). "We have to get the messiah of silence as soon as possible," said Sailor Uranus. Sailor Mercury and Sailor Mars asked the outer planet soldiers to discuss another way, but Sailor Uranus refused. "No! Hotaru's my friend. She's not a bad girl!" protested Chibiusa. But Uranus, Neptune, and even Pluto, turned and left.
In the Deathbuster's hideout, the messiah of silence was displeased with the Professor. "Don't you have any pure hearts yet? Without pure hearts, not just one, but in mass quantity...

Kaori put the tea tray down, and massaged the professor's shoulders. "Ah, you support me completely as my secretary," said the Professor.

"You gave me life, after I died," replied Kaori, "I'll do anything to help make you happy."

 

"Your abilities are wasted as my secretary," stated Professor Tomoe, "I want to see the old you."
Professor Tomoe walked away.
Kaori called after him. "But... I want..."
"I know I can count on you," said the Professor.

The expression on Kaori's face changed from one of happiness to one of disappointment, and then to one of bitterness. Kaori transformed into a black costume and teleported out of the lab.
