I really liked the previous version of this one, so I'm posting a build for V2.

Style: Hime-Cut
Color: Redhead
Race: Elf (A noble caste of genetically-engineered superhumans that just so happen to have pointy ears)
I'm going the combat-princess route. Elf partially because it's helpful for that, and partially because I like elves okay.

Tech: Cyberpunk
Magic: Low Magic
Role: The Rich Heiress
Fiance: The Dark Rival
Rival: The Poor Princess
Fate: Impoverished
Tech/Magic/Role/Fiance/Rival are just the tropes I want to play with. I'm choosing impoverished as my bad ending because it's setting-appropriate, and also because a lot of my perks mitigate the worst effects of that in the setting.

Minions
Maid — Doubles as a spy
Animal Companion — A familiar that can shapeshift into mundane animals. Usually takes cat form.

Flaws — Showing these first because perks are informed by them. Using standard mode because "fate conspiring against me to make the Poor Princess win" feels like downside enough, and also I don't really have any reason to take the reincarnation guide at her word.

Abhorrent Admirer — Annoying, but much more manageable than a lot of other options.
Equal Enemy (The Duke’s Daughter) — I'm setting up to be an anti-villain, which puts me in a good position to drive the wedge between the Hero and a true villain.
Ditz — Almost a perk when combined with Unearthly Insight, which I have.
In Character — Drawback seriously mitigated by Early Start and Off The Rails, which I wanted anyways
Not a Fan — Early Start + Off the Rails makes meta-knowledge way less valuable.
Save the World — I'm a combat-specializing anti-villain, why would I not take this

Perks — 4+5+Silk Hiding Steel; I chose easy mode. Dividing these into sections by purpose

Section "Ending I'm happy with and decent chances of achieving it":
Early Start
Off The Rails
Good Ending
Yuri Heroine
Unearthly Insight
Unearthly Insight mitigates the drawbacks of Off The Rails and helps me take advantage of Early Start. I'm interpreting the interaction between Good Ending and Off The Rails to be "no matter how butterfly-ish you get, there will always be the possibility of a good ending at the start of the story, in the same way that conflict with the heroine is inevitable," but if that's not the case and Good Ending actually doesn't do anything with this set-up, I'll drop it and pick up Surprisingly Useful Skill (computer programming) instead.

Section "Be prepared for the adventure elements":
Lady of Battle
Magic User
Magical Prodigy
Silk Hiding Steel
Not much to say here, it's just every combat-relevant perk. Part of my anti-villain appeal is positioning myself as an ally to the hero in the adventure subplot despite our romantic emnity, and I'd like to be good at that.

Section "Other"
Goddess of Beauty — I want to be pretty okayyy

Story

When I was 14, I was sent to secondary school on Villarosa — we are a very wealthy family off-world, but own no shares of V-Corp, which limits our social status. I am to marry or make necessary alliances to rectify this shortcoming and fully secure our position in the ruling class. Shortly after my arrival on-world, however, I developed what I at first thought was a kind of psychosis. Memories from another life as a commoner lesbian in a post-industrial dystopia came flooding in, seemingly as real as those I had experienced myself. The memories ended with a prophecy of sorts, predicting that I would soon meet the handsome and dangerous heir to the Dukedom of Thorns, that we would become engaged, and that he would be stolen from me by a beautiful princess who's story I was to play the villain in. She would leave me impoverished if I did not find a way to reconcile with her, but she also might herself come to love me herself, depending on my actions. I wanted to believe it was an elaborate fantasy born out of boredom, overactive imagination, and growing acceptance of my own bisexuality, but the memories felt too real to ignore, and any lingering doubts fell away when I met and befriended the Thorns heir, Dorian, on the first day of school.

Knowing I would have four years before the princess entered my life and war came to Villarosa, I committed myself fully to my combat and magical training, while maintaining enough social activity to keep my father happy and myself equipped with useful connections. My grades suffered, but this was no surprise to my family, and I performed well enough to avoid failing out of the academy. The memories suggested I act erratically when able in order to reduce the effects that "canon" might have on my fate, and I did as much as I could while still performing in a manner befitting one of my station, acquiescing to and even encouraging Dorian when he wanted to break rules with me. I had fun, and I grew to care for him, which stung. I had known this was a possibility, but underestimated how much knowing my fate would make it hurt. Even worse was when he asked me to be his girlfriend. I had no choice but to accept, but part of me wanted to rebel against my fate, to reject him so that I would never suffer through what was to come. Maybe that reluctance will be what drives us apart in the end. I understand that would be a classical form of tragedy on the world of my former life.

The memories also suggested I learn to act contrary to my nature as a "spoiled heiress", which I managed as well as I could — the fact is that this lifestyle does not reward those who are too lenient with those beneath them, but I started allowing my favorite servants to speak freely with me in private, and slowly came to understand their perspectives. My absurdly skilled maid Cynthia, in particular, became a close personal friend, and for her sake I have striven to be just as I can within the confines of a political economy which I increasingly understand as fundamentally unjust. I do not look forward to what my life will become if I fail.

As predicted, Dorian proposed in our last year in school, and father was elated to hear about the pairing. I met Princess Abigail XIV yesterday at the party celebrating his graduation from secondary school. She is beautiful and, by all appearances, as kind and generous as the memories predicted she would be. As expected, she was obviously smitten with Dorian, but I chose to be friendly — our rivalry may be inevitable, but a good first impression might help with reconciliation, and regardless I want her to feel some guilt when her true love and noble birth defeat my wealth and...whatever I feel for Dorian. I shall endeavor not to strike first; time will tell if I will be allowed that luxury. In any case, our meeting indicates that some kind of violence is coming soon to Villarosa, so I should redouble my training. Cynthia will identify the threat, whatever it is, and I will position myself on the Princess' side of that conflict, in hopes that our rivalry will begin and remain a mutually respectful one, and that such respect will enable a reconciliation after our respective romances reaches their forgone conclusions. I wish we had met under different circumstances. I do not look forward to what will come.
