Appearance

A palm-sized, fairy-like being, she stays aloft on the air and is bathed in a blue light. Apart from her tiny stature she mirrors Super Sailor Mercury exactly. The monochrome manga renders her glow as nothing more than a large circle looped around her, its shade left to the imagination, while Crystal picks the blue out along the edges of her figure.

Personality

She exists as a piece of the Sailor Guardian she serves, part of Ami just as her Sailor Crystal is. Her manner is gentle and reassuring, and she speaks to what Ami truly wants, reminding her of the wish to shield the people she loves so that the girl can find her footing again.

History

The spirit first arrives in Ami's dream after Fish Eye's Lemures has left her weakening, offering quiet encouragement and returning the Mercury Crystal so the words Mercury Crystal Power, Make Up can revive her Super form. She surfaces again in Elysion as Super Sailor Moon draws out the Holy Moon Chalice, when the solar system soldiers suddenly become their princess selves and their power guardians appear beside them. Positioned before Princess Mercury, Guardian Mercury directs her to feed power from Mariner Castle into the chalice, raising Usagi to Eternal Sailor Moon and letting Ami's Mercury Crystal Power, Make Up carry her into Eternal Sailor Mercury for the first time. After Ami calls on her castle, the spirit vanishes and is never seen again.
