Creator Backlash: PanicAttack towards Rosabella and Kiku, especially the former.
Crosscast Role - The list of female characters actually written by a female is shorter than the list that haven't - discounting NPCs only Procella, Mira, Madison (played by JoJo), Kestrel, Aurica (played by Pancake-chan) and Christine (played by Red). There have been a few males played by females too, most notably Ryouta (again, played by Pancake-chan).
The Danza: Vasco and Procella. Even then, the latter's name was retconned into a middle name.
