A female student of Juuban Municipal Junior High School, Usagi's Fat Friend was known to associate with Usagi Tsukino, Naru Osaka, and Gurio Umino. Despite being keen to lose weight, she was still quite confident in her appearance and apparently considered herself to be more attractive than some of her friends.
Targeted by the Dark Kingdom
Along with Usagi and Naru, she was surprised to witness Haruna Sakurada's quick and apparently effortless weight loss. Umino informed the girls that Haruna had been attending Gym Shapely, a recently opened gymnasium endorsed by the idol Rie Gotou. The girls were soon tempted to join the gym, particularly after they discovered that it was offering free membership. What they failed to realize, however, was that the business was part of an energy-harvesting operation controlled by Jadeite on behalf of the Dark Kingdom.
Usagi's Fat Friend, along with Naru and another friend, eventually tired of the gym's more strenuous activities, and were invited by Jadeite (in the guise of an instructor) to try the gym's most advanced treatment, the Shape Ray. The three girls entered a row of alienesque pods which appeared to reduce their weight significantly, but also left them physically drained. They emerged from the pods looking tired and ill, but Jadeite insisted that they were now more beautiful, and should return for more treatment. Further treatment may well have been lethal, but fortunately that was prevented after Sailor Moon discovered the gym's true purpose and destroyed the operation.
Criticism of Ami Mizuno
Usagi's Fat Friend shared Naru and Umino's early mistrust of Ami Mizuno. After the mock exam results were published and Ami was ranked top in the whole country, she felt Ami was deliberately flaunting her academic prowess. It is not known whether, like the others, she later softened her attitude towards Ami.
Usagi's Fat Friend was impressed by Kijin Shinokawa's work, and considered taking advantage of Kariko Tokoyama's offer of free hairstyling. She was also one of the many girls who developed a crush on Seijuurou Ginga.
Usagi's Fat Friend was never named on-screen, in the credits, or even in the guide books, despite being a recurring character. She was usually credited as "Female Student" or "Girl."
