The Deathbusters | The Witches Five
Eudial
Eudial was the first of the Witches Five to look for heart crystals (three of which makes the Holy Grail). She appeared after Kaolinite's first defeat, and became Prof. Tomoe's assistant after Kaolinite's death. She used a gun to extract the heart crystals from various people. She found out that Sailorneptune and Sailoruranus had heart crystals containing two of the talismans in each needed to create the Holy Grail. But Mimete rigged the brakes in Eudial's station wagon, planted snails (which Eudial hates) in the station wagon, and Eudial ended up driving off a cliff.
Mimete
After Mimete successfully eliminated Eudial, Mimete took over. She would track down someone with a pure heart crystal, let a daimon swallow it, and return it to Prof. Tomoe. The people Mimete had a crush on or was a fan of hers were her usual targets. She died when Tellu pulled the plug on a machine that was supposed to make Mimete stronger.
Tellu
Tellu took over after getting rid of Mimete. She was on the same mission: to find pure heart crystals that may carry the three talismans to create the Holy Grail (confusing, huh? I'm having a bit of a hard time getting all this straight!). She liked nature and plants, and used them to her advantage - she used them to extract the heart crystals from people. Unfortunately, she was killed by her own plants on a mission to retrieve a heart crystal.
Villuy
Villuy was the fourth of the Witches Five. She was knowledeable of computers, and she used them to locate the heart crystals containing the talismans. She also used computers to extract the crystals from humans. And she did it all at Mugaken High School, where Haruka and Michiru attended. She sent a computer to kill the Sailor Senshi, but Sailormoon damaged it and the faulty computer destroyed Villuy instead of the Sailor Senshi.
Cyprine and Puchirol
Cyprine and Puchirol were considered one because they were twins. Others say Puchirol was Cyprine's mirror image. But they always fought together. They tried to find the heart crystals for Prof. Tomoe, but were killed when they attacked the Senshi. The Senshi ducked out of the way and they ended up firing at eachother, thus, ending in their death.
