Mechanics

By voicing the words, Ami Mizuno reworks the geometry of her Mercury Crystal and ascends to her Eternal state. She channels the resulting power alongside the other Sailor Guardians to reinforce Eternal Sailor Moon's Starlight Honeymoon Therapy Kiss, and the combined push brings down Queen Nehelenia.
