Changes from the Manga

  • Only Sailor Jupiter, Sailor Moon, and Chibi Moon attacked Tellu before her transformation.
  • Reika doesn't pull Motoki's ear on the train for complimenting Setsuna on her beauty.
  • Motoki doesn't comment on Reika being afraid of the Mugenzu area as being cute.
  • When Sailor Chibi Moon used Pink Sugar Heart Attack on Tellu, the witch was hurt so badly by it that she had to take on a Daimon form.
  • Makoto suspects Usagi is conflicted because she's starting to develop feelings for Haruka.
  • Makoto tells the boy in the Gardening Club her plants haven't been doing well.
  • Tellu does not absorb any of the Sailor Guardians' attacks
  • Sailor Jupiter's Jupiter Coconut Cyclone was able to counter Tellu's Mandragora Buster, stopping the attack.
  • Tellu did not place herself in a cocoon of vines to transform into a Daimon.
    • Tellu's Daimon appearance did not have any semblance of her human form.

Changes from the 90's Anime

  • Setsuna was never shown to awaken as Sailor Pluto. She already was the Guardian of Time when she met up with Sailor Moon and the others when the Space Sword and the Deep Aqua Mirror were revealed.
  • There were no suspicions of strange shifts in space around Mugen Academy.
  • Setsuna almost fell victim to a Tellun but was saved by her Garnet Rod.
  • Only Sailor Moon, Sailor Chibi Moon, Sailor Pluto, and Tuxedo Mask had fought Tellu.
  • Pink Sugar Heart Attack had a more comedic, childish effect on its opponent.
  • Luna P never turned into the Pink Moon Stick. Sailor Chibi Moon already had it with her when she returned from the future.
  • Tellu never took on a monstrous appearance.
  • Tellu could release vines from her hand, which would constrict her victim and electrocute them.
  • Tellu perished when she grew a Tellun into a giant, Tuxedo Mask destroyed her amulet holding the Pure Hearts, freeing them and the Tellun attacked her and forced her to use her electric vines attack it, destroying them both.

First Appearances





  • Sailor Pluto "returns" in the form of a human woman named Setsuna Meiou.
