Amy Mizuno (水野 亜美 Mizuno Ami?), is one of the central Sailor Guardians and a protagonist in Sailor Moon Crystal. Ami is the reincarnation of the Princess of Mercury. Reborn on earth, Ami is the daughter of a doctor and the civilian identity of Sailor Mercury. A genius-level student, Ami is a somewhat social recluse who befriends Usagi Tsukino following the foiled Dark Kingdom plot against students in Ami's calss.[1] Ami tends to act as the Guardians soundboard of reason and tactical measure.


Previous Life

Rebirth on Earth

Dark Kingdom Arc

Ami makes her debut appearance in the first episode, but as a non-speaking cameo, at the very end of the episode, she retreats for cover at Juuban middle school as a rainstorm begins to occur.

She reappears in the second episode, in which she becomes Sailor Mercury for the first time in Crystal. In this episode she is seen as a shy girl without many friends. When Usagi meets her, they hit it off well. She is soon brainwashed by the Dark Kingdom at the Crystal Seminar, but is snapped out of it when Usagi as Sailor Moon is in danger. Seeing Sailor Moon in danger allowed her to awaken her powers, and she transformed into Sailor Mercury.

Black Moon Clan Arc



In the second anime series, Ami retains the same appearance as she did in the manga: jaw-length bobbed blue hair that is a few inches above her shoulders and blue eyes. She wears her Juuban middle school uniform, coupled with a grey cardigan, short white socks, and brown penny loafers.


Ami is a fourteen year old girl who attends the Juuban Municipal Junior High School. She is known for studying a lot because of her wish to become a doctor like her mother.


  • Unlike the original anime, and the first act of the manga, Ami makes a cameo appearance in the first episode of Crystal.
  • Her name is a homonym meaning "Asian Beauty of Water".
  • Ami appears to be more sociable in Crystal compared to other versions.
