In the manga, Cyprine and Ptilol were summoned by Kaolinite to kill the students that had escaped Mugen Gakuen. After an unsuccessful attack on Haruka Tenou, the two used their powers to manipulate the feelings of the Senshi into attacking each other. They were finally killed by Super Sailor Moon with her Rainbow Moon Heart Ache attack.
She taught the witch training class at Mugen Gakuen and was ranked at Level 999.
- Ribbon Buster - Cyprine's primary attack in the manga.
Cyprine and Ptilol made their first and only appearance in episode 123 of the anime, and claimed to be the strongest of the Witches 5. Indeed, the Sailor Senshi had a difficult battle against them because when one witch absorbed an incoming attack, the other would fire an attack of her own. When they absorbed any attack with their magic staffs, their own magical powers would increase. The Senshi only managed to destroy them by tricking the two into firing their attacks at each other.
Cyprine's strategy to capture Pure Heart Crystals was to gather all of the Mugen Gakuen students near the statue of the Messiah of Silence deep within the school, which would then collect their Pure Hearts. The statue shattered when Cyprine and Ptilol were destroyed.
Cyprine often flirted with Professor Tomoe in the lab, which caused Kaolinite to be extremely jealous. She seemed to enjoy taunting Kaolinite in this manner.
Cyprine is named for a blue variety of vesuvianite known as cyprine. The word "cyprine" itself is derived from "Kypros" (Κύπρος), the Greek word for "copper," which gives the mineral its color.
