Mikuji

Mikuji was the first known Daimon hatched by Kaolinite to draw energy for Professor Tomoe. She was incubated in a cherry tree and attempted to steal Rei's Pure Heart Crystal. She also broke the Cutie Moon Rod and the Crystal Star, and proved to be too strong for the Inner Senshi to fight. Sailor Uranus and Sailor Neptune finished her off with World Shaking and Deep Submerge, then returned the Crystal to Rei's body.
