The base door.
After the first death of Kaorinite, they took over the task of extracting Pure Hearts. Their room is behind a door labeled "Witches 5". Comically, after Eudial's death, a poster is put up near the end of the writing so it says "Witches 4". After Mimete's death, another poster is put up to make it read "Witches 3".
Anime
Eudial is the leader of the Witches 5, and the first to extract Pure Hearts. Her methods involve her using a heart snatching gun to extract Pure Hearts, then summoning a Daimon Heart Snatcher to destroy the Sailor Senshi as they attempted to interfere. She usually drives a car, and attacks by using flamethrowers. She was killed when she crashed her car over a cliff as a result of Mimete cutting the brakes to her vehicle.
Mimete is the second of the Witches 5 who always picked on Eudial. Her Daimon Heart Snatchers suck their victims' Pure Hearts out through their mouth. Her targets are always well-known attractive young men. She attacks by shooting a star beam. She entered Eugeal's power device, but was killed when Tellu pulled the plug on her for stealing her job.
Tellu is the third of the Witches 5. Her strategy involved using plants called Telluns to extract Pure Hearts. She attacks by using vines that can electrocute her victims. But one of her plants, whom she transformed into a plant monster named Hyper-Tellun, attacked her and selfdestructed, killing her.
Viluy is the fourth of the Witches 5. Her strategy involved using a master computer to extract Pure Hearts from exam takers of Mugen School. She uses a bracelet called a nanocuff to shoot a nano ray that can dissolve her enemies, but this bracelet was damaged by Sailor Moon, and the nano ray turned on her and dissolved her.
Cyprine is the fifth of the Witches 5, and shares her mind and body with Petirol. They attack by shooting energy waves from their staffs, and use a glass statue to extract Pure Hearts from the students of Mugen School. Sailor Mars and Sailor Jupiter tricked them into attacking each other, destroying them both.
Manga
In the manga, the Witches 5 were perfect Daimons created by Professor Tomoe. They took orders from Kaorinite and posed as students in Mugen Academy. They were each assigned to collect Hoste (or souls) and use their bodies as vessels for Daimon eggs. They only made brief appearances in the manga. In the manga, all of them displayed the Death Busters symbol (a black star) on their foreheads.
