!!![=YMMVs=] introduced by ''A's'':

* DesignatedVillain: [[spoiler:Graham]]. For some reason some fans still believe that he's the one who gave Hayate the Book of Darkness. Which is not true, Hayate already had the book before he discovered her.
* EnsembleDarkhorse: The Wolkenritter, particularly Signum and Vita.
** Reinforce as well.
** The Yagami family as a whole is very popular among the fandom. Hayate being a fan-favorite, and the Wolkenritter being very popular and the Unison Devices being also very liked, it's not surprising why there are so many fanart about the them.
* EpilepticTrees: In the manga Suzuka beats Fate at dodgeball [[BadassNormal by catching a ball thrown with Super Strength and knocking Fate out of the sky with her return throw]], in the anime both her and Alyssa appear inside a barrier that was supposed to keep {{muggles}} out. People familiar with ''TriangleHeart3'' might remember Suzuka's sister Shinobu was a vampire there. Suzuka herself didn't exist. ''Hmmm...''
* EvenBetterSequel: The only one so far ''not'' to have caused a BrokenBase of some sort.
* EvilIsSexy: Reinforce, for a given value of "evil". Also, the last boss has breasts for no apparent reason other than this.
* GrowingTheBeard
* HilariousInHindsight: During the commentary of ''The Movie 2nd A's'', Caro has a some dialogues with (adult) Chrono. This is of course hilarious if you think about that Creator/MikakoTakahashi plays both, Caro and the young Chrono. This is a funny [[AvertedTrope aversion]] of TalkingToHerself.
* JerkassWoobie: Vita, before meeting Hayate, was a jerk even to the other Wolkenritter as shown in the sound stages, and harshly rebuffed Reinforce's efforts to reach out to her. She who also the one who seemed to suffer the most from a life of constant fighting.
* LoveItOrHateIt: The movie suffers from this greatly.
** Either you loved it for the visuals, Fate's development and Fate and Nanoha's friendship, or you hated the movie due to bland music and fight sequences, Yuuno basically being written out of the movie, Lindy and Chrono never getting any closure to what happened with the Book of Darkness as well as the fact that the Wolkenritter held onto both the IdiotBall and the ConflictBall just to make the plot work.
** About the only things universally praised by all fans in the movie was the cleaned up visuals, fight against the Darkness of the Yami no Sho and Reinforce's device being cool. However, the first action sequence is also universally disliked by fans, good luck getting them to agree on the why of that, however.
* MostWonderfulSound: The cartridge loading sound.
* {{Narm}}: In retroperspective, Signum's voice was higher in early episodes, which can feel rather odd. It became deeper after a few episodes, even though not as deep as she sounds today, but the odd feeling is not as strong than in the early episodes.
* TheyWastedAPerfectlyGoodPlot:
** We never find out how Hayate reacted to hearing about [[spoiler:Graham having planned to use her to seal away the Book of Darkness]], or if she ever found out at all.
** Kyouya and Miyuki are shown to be expert swordsmen in ''TriangleHeart3SweetSongsForever''. One of the enemies their sister is fighting in ''A's'' is a sword master. Despite the obvious opportunity for a duel between Signum and either non-magical Takamachi sibling, the most significant event featuring those two in that season is Miyuki ribbing Kyouya about his love life.
** Considering how much Vita prides herself on there being nothing in the world she cannot break, why didn't she ever seek out a rematch with Yuuno Scrya, the boy who -- without any Device and lacking her centuries of combat experience -- managed to fend her off entirely without even giving her the dignity of his full attention? There's no way that he wouldn't have infuriated her, and no way she would have forgotten or forgiven the offense to her pride. At the very least, she should have become the SECOND antagonistically snarky bane in his life, after Chrono.
* TooCoolToLive: The original [[spoiler:Reinforce]].
* WheelchairWoobie: Hayate, whose inability to walk is less of a concern to her than her loneliness and potentially shortened lifespan.
* TheWoobie: All the antagonists to some degree.
