In the anime adaptation, while ditzy and targeting celebrities, Mimete is assigned to collect Pure Heart Crystals after she orchestrated Eudial's death. Out of all the Witches 5, she is the least organized and the most easily distracted. She can launch mirages in the shape of stars at her opponents and induces severe vertigo and disorientation, capable of rendering someone unconscious in seconds. After several failed attempts at collecting hearts, she tries to use one of Eudial's abandoned inventions (Witches Electric Warp). The machine would transport a person inside of a television, which would increase that person's power exponentially. However, if the power to the television were disconnected while the user was still inside, the user would be trapped within it forever (the exact reason why Eudial never used it). Tellu mercilessly imprisons Mimete by pulling the plug off the machine.
In the original anime, she is voiced by Mika Kanai and in Crystal, she is voiced by Yuki Nagaku. Catherine Disher provides her voice in the Cloverway Inc. English adaptation, in which her name is changed to "Mimet". In the Viz Media English adaptation, she is voiced by Kira Buckland. In the musicals, she is played by Shiori Honda and Aki Kudou.
