Florence Trent

A confirmed member of the Terror, the player characters know Florence Trent from a photo involving her, Gabriele, and a Stand user they believe to be linked to the city's erased victims (Curtis).  They've found traces of her posting online on Usenet (mostly debunking Nemo's conspiracies) and sending emails to the landlords that closed Quentin's theater.  She seems like an incredibly serious person, and shouldn't be underestimated.

Known Backstory:

According to her, she and Gabriele were previously homeless, until "their boss" (later revealed to be Anthony, much to the players' astonishment) took them in and "gave them everything," including her Stand ability.  Unfortunately, circumstances prevented any further elaboration, but it's safe to say Florence is telling the truth about her and them, given they're in a relationship and even live together.

As part of the Terror/Delta Machine, the duo goes along with Anthony's instructions, up to and including assisting in abductions and murders.  While they're aware of the brutality of it, to them, it's just the price to pay for a comfortable life.

In-Game Timeline (Act 1):

Besides her online activity, she seemed to just be out and about the town, just not coincidentally in the same areas as the party at the same time.

She and Gabriele together appeared to be monitoring the party's actions through a system of security cameras downtown.  Gabriele would correspond via phone to obtain information along with "missions" for both of them to do, and when the party found their phone number, Florence gladly talked to them, identifying them by name, intentionally revealing she knows who they are.  She didn't reveal much besides that though; she mostly just threatened them and hung up.

Quentin and the party later tussled with her and her ability, and Kathy tried to dig up any extra dirt on her on behalf of the party.  The ongoing conflict with Florence rose to a life-threatening fever pitch, but then the scene was cut short by the reality-warping Stand that controls the city, it seemingly crying out in distress for the fight to "just stop."

In-Game Timeline (Act 2):

A mysterious Stand called「Endless Fantasy」overwrote the memories of parts of the city and characters' relationships while simultaneously skipping time forward a couple months.  The players and NPCs were victims alike, and eventually regained varying degrees of knowledge of what had been reset.  She and Gabriele had become friends with the party(!) and claimed to be members of a property management firm called "Delta Machine."  The players knew this previously as the name of an organization trying to get Anthony elected...but the player characters didn't remember that anymore.

Suspicion set in anew as Kathy began her investigation anew in this timeline, and Delta Machine itself still seems to be some sort of front, potentially connected to both the Terror and the mafia (or are the Terror and the mafia one and the same?), and definitely connected to Anthony.  Indeed, this suspicion was proven correct when the two of them began to attack the party once more, shortly after they had all broken out of Endless Fantasy's grip.  The final confrontation with the duo happened with the party's effort to save Daniel and Laurent from an attack by Delta Machine.

After a struggle, Florence eventually surrendered, getting Gabriele to stand down as well.  She confirmed a fear about the nature of their previous friendship: Endless Fantasy had influenced them both to be friendly with the party, and they had returned to their duties only after breaking out of it.  This strikes the players as odd, considering Endless Fantasy is thought to be their enemy, assumedly in line with Delta Machine's machinations.  Whatever the case, it's this taste of friendship that created this new opportunity for peace.  Betraying Delta Machine comes with a cost, however: Florence and Gabriele now demand the party's protection, as the rest of the organization will be after them in order to silence them.  Are they up for the task?

Ability:「Pretty Hate Machine」

Close-Range, Natural Humanoid

Pretty Hate Machine targets a singular person Florence wants it to "haunt," following behind them silently.  While the target is being pursued by PHM, they start to feel an increased sense of fear and paranoia, like someone's watching them.  If they turn to look, see PHM, and are startled by it, PHM stabs them with its arms.  The stab is not actually corporeal, but it infects the target's mind, throwing them into a state of intense hallucinations that creep up on them slowly.  The hallucinations are where the true attack lies, as the victim could accidentally harm themself or others through the actions they don't realize they're doing.  The effect persists outside PHM's range; Florence is the one that has to "cure" them.

It resembles a human woman with long ghostly hair and giant lances for arms.

Other:

• She's meant to be like a "small" character Araki would draw (Koichi for example).  Her real height is probably more like 5'0"; her tininess is pure Jojo Logic.
• She was created to be a foil to a player character that's also desperately searching for a purpose in life.
• She would have a "Southern belle" look about her, if her stare wasn't so icy cold.
• Her name references Florence Welch and Trent Reznor.  Florence + the...Pretty Hate Machine.
• The cat plush she carries with her was a gift from Gabriele.  They share an apartment together, and are absolutely kissing.
• Her abilities were inspired by the Hinamizawa Syndrome from Higurashi.
• Her Stand was partially designed by Bee.
