Code name of Ami Mizuno, one of the earliest members of the Sailor Scouts, she wields the power of water. A technical and scientific devotee, she tends to be more strategic than her comrades. She uses the Super Micro Computer, a powerful PDA with as much functionality as a tricorder. This is often used in conjunction with a visor activated by touching her earring. The visor functions as a heads-up display and also allows her to see things outside the normal range of human vision.
