Mimi Hanyu
Mimete, formerly of the Witches 5, revived when she was extracted from the Electric Warp because Tomoe needed a warm body to play twister with. Now she works diligently to help him rebuild his Labs, and surprisingly finds him more than willing to let her into his life... now if only she could win over the rest of the Ten'ou House... not that she cares about them anyway, damn senshi.
She has her Doctorate from Mugen Gakuen now, and fills the role Kaolinite used to.
In her past, Mimete, as Mimi Hanyuu, was a famous idol who appeared in commercial and on television. She was also the entertainment instructor at Mugen Gakuen.
She was ranked the lowest at Level 40, and was also the weakest and required the assistance of Kaolinite in order to attack the Sailor Senshi. Sailor Uranus eventually defeated her.
She was killed on November 9th, 2014 during the Third Nonary Game, but her soul was retrieved from The Abyss on November 23rd, 2014.
