* AlternateCharacterInterpretation: Due doesn't seem so heartless this time and seems to enjoy teasing Tre. Then again this is probably a ShoutOut to one of Nanya's other works.
* ArchivePanic: 200+ chapters and 400,000+ words and still no signs of stopping.
** The author has stated that he has plans to go all the way through [[Manga/MagicalRecordLyricalNanohaForce Nanoha Force]]- though he later gave up, likely due to how poorly it was written.
* FanNickname: Reinirvana: Anytime Reinforce Zwei does something incredibly cute, you can feel your troubles just melt away.
* HilariousInHindsight: In the ''Peek'' arc, it is revealed at least in this story that Reinforce Eins is a human turned into a Unison Device. With the release of ''VideoGame/MagicalGirlLyricalNanohaAsPortable'', it is revealed that the Unbreakable Darkness, aka the Darkness of the Book of Darkness, was a human that got turned into a Device.
** In the ''Revolution'' arc [[spoiler:Corona gets a ton of pure Black Magic poured into her Linker Core, causing her to undergo a massive change in personality]], in the 2nd movie, guess what happened to Hayate thanks to the Protection Program?
*** Speaking of the second movie, in the A's arc of this fic, the Protection Program fought back against everyone before being taken down, and, yes, it happened in the movie as well.
*** Sticking to the 2nd movie, in Blood That Flows, it's revealed that Reinforce had a device in the past. In the movie [[spoiler:she has Nachtwal.]]
*** [[spoiler:Which sprouts CombatTentacles. Reinforce also used CombatTentacles in the Strikers arc of this fic.]]
** [[spoiler:Arisa's]] Holy Power manifests in a way that [[Literature/ShakuganNoShana she has flaming wings and a sword of fire]]. Enter ''Manga/MagicalGirlLyricalNanohaInnocent'' which gives her that very power.
** It's gotten to the point that both the author and readers joke that Tsuki is stealing the author's ideas.
* TheWoobie: Filia for a point, after seeing first hand of her [[BrokenPedestal race's corruption]].
** Lutecia falls into this category. Her body's been modified so that she's physically older, has become completely subservient to Levi, and she's been sexually molested and taken advantage of by Levi several times.
