A Vivio-centric ''MagicalGirlLyricalNanoha'' fanfiction series by [[http://www.fanfiction.net/u/746291/DezoPenguin DezoPenguin]], with the main attraction being the novel-length ''Stahlkönigin''. The stories are, in order:

* ''[[http://www.fanfiction.net/s/4580614/1/The_Road_Onward The Road Onward]]''
* ''[[http://www.fanfiction.net/s/4610048/1/Shell_Game Shell Game]]''
* ''[[http://www.fanfiction.net/s/4664010/1/Steel_Wings Steel Wings]]''
* ''[[http://www.fanfiction.net/s/5051144/1/Memory_of_a_Saint Memory of a Saint]]''
* ''[[http://www.fanfiction.net/s/4854066/1/Caramel_Milk Caramel Milk]]'' [[note]]Technically, this takes place some time during ''Stahlkönigin'', but leaving it for last would be a bit of an anticlimax after said fic.[[/note]]
* ''[[http://www.fanfiction.net/s/5086723/1/Stahlkonigin Stahlkönigin]]''

The series was started before ''[=ViVid=]'' was released, and is now an [=AU=], but that doesn't detract from the quality at all.
----
* AlternateUniverseFic
* AnAxeToGrind: Signum briefly runs afoul of a terrorist wielding a Device of this nature. [[LadyOfWar Very]] [[CurbstompBattle briefly.]]
* BeamSpam: '''[[spoiler:Plasma Lancer: Legion Shift]]'''
* CurbStompBattle: [[spoiler: Fate and Signum both deliver one each, to Sonoma and one of his lackeys, respectively.]]
** How does [[spoiler: Fate]] take [[spoiler: Sonoma]] down? [[spoiler: Bardiche]] interrupts his quick teleport spell with [[spoiler: [[{{BFG}} Thunder Rage]]]]. Why? because it was ''fast and easy''.
* IHaveYourWife
* JustInTime: Referenced by Hayate, but averted.
* KillSat: [[spoiler: Heimdall.]]
* KnifeNut: [[spoiler: Sonoma.]]
* NeverASelfmadeWoman: Subverted. Vivio initially ''assumes'' this to be the reason she's being invited into active service before completing her formal education; turns out it's just that she happens to fit a hole in a new squad's lineup.
* ShutUpHannibal: [[spoiler:Fate delivers a grand one to Sonoma near the end.]]
* ScrewDestiny: [[spoiler:Vivio partially derails one of Carim's prophecies by tanking Nanoha's Blaster System-enhanced [[WaveMotionGun Starlight Breaker]]... well, its splash damage, anyway. Still impressive.]]
* StoneWall: Vivio. Her offensive abilities are paltry compared to most other mages, and her mobility is mediocre, but her defenses are nigh impregnable.
* TrainingFromHell: A mild example in comparison to some, but Vita's 'training' of Vivio is such that broken bones are considered an expectation, rather than a cause for alarm. [[spoiler: Amusingly, the ''trainer'' is often the one breaking things trying to punch through Vivio's ridiculously strong defenses.]]
** And then there's Nanoha and her exaggerated reputation for this.
* WeakButSkilled: Vivio, after a fashion. Despite technically being weaker than most of the canon cast, she's able to keep up very well through general versatility and inventive use of the things she does excel at.
