Cyprine and Ptilol were the fifth member of the Witches 5 to appear in Sailor Moon S. According to the Materials Collection, the two of them were one "twin," but when they fight Ptilol would split away from Cyprine.
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 Academy 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.
In the manga, Cyprine and Ptilol were summoned by Kaolinite to kill the students that had escaped Mugen Academy. 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 Heartache attack.
She taught the witch training class at Mugen Academy and was ranked at Level 999.
- Ribbon Buster - Cyprine's primary attack in the manga.

Cyprine appeared in the musical Mugen Gakuen - Mistress Labyrinth and its revision, and was played by Michiho Matsumoto and Saeri Amano. In the musicals she appeared only by herself, without Ptilol.
- Magus Drive - Cyprine's primary attack in the musicals.
Cyprine appeared in chapter five of the video game Sailor Moon: Another Story, as a boss in Crystal Tokyo.
- 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.
