Vita

ヴィーター

__Vita in Mahou Shoujo Lyrical Nanoha A's__ Vita enters A's on a hunt with Zafila for strong Linker Cores to absorb into the Book of Darkness. She targets Nanoha Takamachi, which she deems to be a juicy target, unlike the usual TSAB "redshirts" which can barely fill up a single page of the Book of Darkness. Nanoha puts up a decent fight, but Vita tilts the deck with two cartridges (bullet shaped things that contain high-pressure magic) manages to overpower her, obtaining a power superiority so vast that she heavily damaged the Raising Heart. However, before she could get the Linker Core, Fate Testarossa and Yūno Scrya come to the rescue. Vita fights them off with her fellow Wolkenritter, Signum and Shamal, and they declare themselves enemies. The battle ends with Shamal finally managing to get Nanoha's Linker Core and Nanoha breaking Vita's barrier. ~! Vita fights for the sake of protecting their mistress, Hayate, whom she is completely dedicated to and possibly (in the manga, certainly) in love with. The Wolkenritter attack mages to steal their Linker Cores, their sources of magic, to fill the 666 pages of the Book of Darkness with this power before it saps any more of Hayate'
