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.
Draco in Leather Pants: Blackbird gets this a bit. It helps that most of her villainy was offstage, but even after she stabbed Meron, some fans still like to view her and her obsession with Veloce in a positive light.
Fan-Preferred Couple: Veloce/Blackbird is by far the most popular ship in this series. Meron/Des seems to be quite popular as well, what with Des' almost blatant crushing on her.
Les Yay: Meron seems to be in love with Veloce. She's spent four years trying to gain the latter's forgiveness, and she has no problem with dying if it means Veloce's life will be easier. Hell, at one point, after Veloce rebuked her, Meron broke down in tears. For Veloce's part, she tends to act like a Tsundere who's been hurt by Meron in the past and is now trying to decide if she should forgive her or not, but either way still cares for her.
The Scrappy: Keritzel is not exactly popular thanks to his youthful naivete and optimism. Some fans even think that Shilin purposefully made him this way so that he could be broken at some point in the future.
