Yeah, while it does say that using the Pazuzu Whip to don her alter ego makes her have less inhibitions, it's never stated that Mrs. Victoria isn't the same "person" as D. Violet or vice versa. Either it's just her being able to act with less inhibitions when in her disguise (since she doesn't need to maintain the appearance of being a teacher) or the whip does have some effects on her mentally, but there's no reason to believe that D. Violet is a different personality.
(Does the emoji for a Ribbon show up?) Mhm, mhm! We can see either or! We don't mind however Mrs. Victoria ends up, I guess if you want we have a teeny explanation why we attached:
How our plurality works is we sorta "transform" into one another, there's not that "watching someone else control your body with you in back" feeling some other systems get. Even though we said we had a demon alter and hypersexual alter, they still *mostly* share the same core/base/memories with everyone else. So that's why we sorta liked the idea of Mrs. Victoria having that, cause it'd be like us! o((>ω< ))o (Oh! And just to let you know, "personality" is considered an outdated term, the modern terminology is "alters" and "headmates", like 'alter-ego'! Eheh. (๑•̀ㅂ•́)و✧)
The idea of them being different personalities and one of them not being aware of the other could be cool, although it's not exactly a novel concept for superheroes. Moon Knight is a good recent example.
Yeahhh true! Plurality actually often crops up in superhero media, a lot more than you think! (っ °Д °;)っIt's probably just cause of the inherent dichotomy of one's public and superhero personas being contrasting states of being, so writers tend to do that! Like with Batman's Zur-En-Arrh, or The Hulk, or Moon Knight, etc etc.
Though one thing we DO think would be a novel concept (and this doesn't have to be Mrs. Victoria it could genuinely be anyone else) is the idea of "the normal system stuck with the wacko fantasy systems". In other words, when systems are portrayed in media, more often than not they're usually the ONLY plural character on the block. And that's well and good, but sometimes it can make it feel a bit, hmm, like a spectacle I suppose? "Look! It's soooo rare and different!", not realizing that studies show systems are more common than redheads (no, really! (๑•̀ㅂ•́)و✧)
Unlike a number of series though, Skullgirls already did the heavy lifting to make everything quite plural! ╰(*°▽°*)╯So playing from the perspective of a normal system that's observing the environment would actually be quite interesting and cool!
It's the compare and contrast for us, mostly. We ourselves have written, say, a regular system discussing things with a person who consensually gets possessed by a ghost. It's fun, it's freeing, and... kinda normalizing! We like being seen like that. (●'◡'●) - Ribbon
I wouldn't rule out the possibility of Fukua actually having multiple souls either but yeah I think it's worth to have some caution about putting too much stock in the bio description, which was written basically as a joke for her April's Fool trailer. They seem to be taking an interesting direction with Fukua in Dahlia's story so we might get more details about her canon nature or origin at some point.
Oh yeah don't worry! We're treating it with a grain of salt tbh. Plurality is so often misrepresented in media that systems like me sorta have to scrounge for scraps, eheh ;^^
