Cyprine and Ptilol
Cyprine is the final and most powerful of the Witches 5 to appear. By this stage, her goal was to collect as many Pure Heart Crystals possible and to kill off the Sailor Senshi. She awaits for the Sailor Senshi at Mugen Gakuen and later splits into 2 people, the other being Ptilol. They are both essentially the same person (and thus 'Witches 5 and not Witches 6')- and together can absorb any attack coming their way. The 5 soldiers team up and strategically separate the two and in the mist of the battle and confusion, they end up killing each other.
