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.
Complete Monster: Ruko, Mirsha, Derlyn, and Xana's puppeteer, is definitely one of these. She enjoys torturing the former two, and the only reason why she won't torture the latter one is because Moogi won't let her.
Larcy. Do you want to know how bad it is? Well, he caused Turo to cheat on Xana to save his position on Team Shenkuu, and attempts to murder Foltaggio just so he can win Mirsha. Because she already hated him before then, naturally, it doesn't work well. It results in Mirsha killing him.
Ensemble Darkhorse: Lilo, Stelle, and Kaine all scored relatively high in the roleplayer popularity poll, to everyone else's surprise. The earlier two are Darkhorses for their lighthearted personalities, and the latter one is likely a Darkhorse for just the opposite reason.
Arguably Derlyn counts, as she also scored high on said popularity poll, but she's the female lead who was probably loved before then, so she's probably more of a Breakout Character, as she is the female lead.
Genius Bonus: Lampshaded when Raven calls Tandrak Edmond Dantes as a reference to how both had Meaningful Renames. Tandrak, Valka, and just about everyone else dismiss this as gibberish.
Harsher in Hindsight: Kaine's Magical Girl uniform is purple and black, and part of her hair is green. The only other character with that color scheme is Layton, Kaine's dead husband.
One of the major jokes concerning Tanven is that Tandrak gave Garven Laser-Guided Amnesia in an alternate canon, and Valka is always the one to bring this fact up? Guess what happens to her much later on?
While Star Corporations was always corrupt, theirs came when one of their Magical Girl experiments, Etoile, went against them. Years afterwards, they sent in another one, Stelle, to murder one of her own kind, and even claimed that if she didn't, her family members would die. Not only that, but Stelle used all her powers at once in said battle, causing her to almost die herself.
Xana agrees with Mirsha on this after Lor traumatizes Antola.
Portmanteau Couple Name: Antariel, Xantola, Tanmu, Layka, Valdrak, Elariel/Prelon, Shaylis, and Gardrak/Tanven... just to name the ones made up so far.
However, the name 'Shaylis' was also the name of a rogue alliance that targeted Valka. Also, no matter how many times a Ship Tease happens, Valka denies Valdrak at just about any turn.
Not as much as she denies Valvon!
Rule-Abiding Rebel: Tandrak to an extent; although he isn't that much of a rebel in the actual roleplay, Valka claims he tried to sabotage the Cup before... he denies it.
The Woobie: While many of the characters have these moments, Valka probably breaks the record, considering that she has to deal with the fact that her mother died via Heroic Sacrifice, her father grieved so much that he put her up for adoption, her own daughter suffers the same fate as she does, and was kidnapped so that she could become a member of Star Corporations again, had Layton not come in at the right time...
