Tellu made her debut in episode 120 of the anime, when she purposely unplugged Eudial's abandoned invention, the Witches Electric Warp, while Mimete was still inside it, thus killing her. After Mimete's demise, Tellu took over leadership of the Witches 5.
Instead of using Daimons she sold Telluns, plants that she had created with the purpose of extracting Pure Heart Crystals. She was killed by her own creation, the Hyper Tellun, after Tuxedo Mask broke her Pure Heart Crystal storage container with a rose, leaving behind her Mugen Academy student ID. This information gave the Sailor Senshi the location of the Death Busters' whereabouts.

Tellu appeared in the musicals Mugen Gakuen - Mistress Labyrinth, its revision, and Un Nouveau Voyage, and was played by Mio Nunokawa, Akiko Iwasaki, and Momoko Sadachi. In the musicals, Tellu was often separated from the other Witches, as she was preoccupied with perfecting her Telluns.
