These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: The Ninaganger. She was incapable of more than childish pranks and felt guilty the one time that wasn't the case. Channeling Nina's mentality is probably why. Considering Nina got a crush on Kade similarly to how the Ninaganger had and all.
Ace and Brooke's relationship going on and off has sparked quite the debate recently. Do they work as a couple? Are they dragging it for too long that it gets boring to read? It doesn't help Brooke dumped Ace after Tia undid his growth spurtnote which he had gained from accelerating through puberty, thanks to the Tiresias Orb, as well as being upset with Ace for going out with Nina and kissing her, despite having done the same with Tabitha. All which caused some readers to Abandon Shipping.
The Hellrunes were added to the list of characters that got a pinup if you ordered the print edition of Vol.0, and were eventually given their own spin-off.
Tiffany's fans loved her for being a Large Ham and a ditz, not to mention, all the Les Yay between her and Layla. She became popular enough that she was given a bigger role in the Magick Chicks spin-off.
Fan Nickname: A large portion of the fandom insists on using the name "Grace" for Ace since he became a girl, even though he's never been called that in strip, or even been addressed with female pronouns.
It's later revealed that his father called her Acina after the Gender Bender.
Dio's ongoing relationship with Ash came about as a result of a blastfrom Mel's wand. Which caused some minor contention among the fans, since both characters had been heterosexual, until that moment, and the effect has yet to be reversed.
Brooke secretly nurses a one-sided crush on Layla and was given a Practice Kiss by her, after asking Layla to show her how, in return for giving Layla some of her blood. Though now that Layla's regained her memories as Queen Quintessa, she's shown up in Ace's dream, along with a past incarnation of Brooke, and says she belongs to her.
In-Universe too, as most of the girls vote on Brooke sleeping in a different room after hearing the story.
The Scrappy: As you can see from the examples below... yeah. That said:
Nina is the main one among the readership, due to her naivete which is meant to be an endearing quality, but often comes across as childish and annoying instead. Made moreso, since it's usually either her sister, or Ace, who suffers from her actions, or the resulting fallout.
Dio is fast on his way to becoming one, himself, between being a snob and his Fantastic Racismtowards Ace being a werewolf. Plus, the fact that he's stringing Layla along, while secretly waiting for her sister regain her adult body, so he can switch to her.
