Doctor Tomoe created Utomodachi from a comic book and Mimet took her with her to extract a Pure Heart from Mr. Kazama, a soap opera actor. However, she was unable to extract the Pure Heart because Sailor Uranus attacked her. The Sailor Scouts showed up afterward, and Mimet left, telling Utomodachi to fight them. She hated them too much to want to fight them, so she instead ran off in Hotaru's direction. Before she could kill Hotaru, however, Hotaru paralyzed her with her power, and Sailor Moon transformed into Super Sailor Moon and destroyed her with Rainbow Moon Heart Ache.
