She was created from the page of a comic book by Professor Tomoe, and attacks by throwing razor sharp book pages and trapping people with giant covers of books. Mimete brought U-Henshū with her as she targeted a writer named Ukon Katakuri. U-Henshū sucked the Pure Heart out through his mouth and ate it. Sailor Moon attacked her, but became trapped under a giant book cover. Then Sailor Pluto, Sailor Neptune, and Sailor Uranus arrived and attacked U-Henshū, but were at a disadvantage until the other Sailor Senshi came. U-Henshū ran out of ammunition, and Sailor Moon used Rainbow Moon Heart Ache on Mimete and U-Henshū. Mimete ran off before the attack reached them, and U-Henshū was destroyed.
