Ami Futami is a 12-year-old idol at 765 Production and the younger half of an identical twin pair with her sister Mami Futami. While visually identical to Mami, Ami is distinguished by a red hair accessory fastened to the left side of her head. She radiates mischievous energy and delights in pranks and chaotic antics, though she and her sister respect firm directives from authority figures like the Producer or Ritsuko Akizuki, accepting disciplinary tasks such as office chores without protest. Ami refers to herself in the third person, mirroring Mami and fellow idol Miki Hoshii. Professionally, the twins share the singular stage name "Ami," alternating performances to conceal their twin status, a secret kept by 765 Production staff and Takane Shijou. Public audiences sometimes mistake their identities, though subtle clues like Ami’s tendency to doodle on surfaces can help tell them apart. The twins are known for warping song lyrics, inserting phrases like "Tokachi tsukuchite" into "Agent Yoru o Yuku," which earned them the fan nickname "Tokachi." They have an overprotective mother and occasionally flee to the 765 office for respite. Their shared life includes a joint email address and a fondness for handheld gaming devices. Ami’s corresponding Puchidol is Koami, a small creature that shares her fondness for pranks and is identified by its hair pin placement. Together with Mami, she discovers the Puchidol Afu on the street and successfully requests the Producer’s permission to keep Afu and another Puchidol, Yukipo, at 765 Production. When Ritsuko demands the return of the Puchidol Takanya to Brazil, the twins intervene and adopt Takanya themselves; Takanya rarely speaks, primarily communicating through writing that often uses two-kanji compounds and idioms. Ami has grappled with a post-debut slump, channeling renewed resolve to reclaim her status as a top idol, a drive that sometimes steers her toward impractical goals yet underscores her tenacity. She often seeks the Producer’s company during off-hours, inviting herself on errands or outings, reflecting their casual but devoted rapport.
