"The next-to-last perk is Unearthly Insight, which lets you put things together and discover secrets more easily--it can come in the form of a minor divination talent, or just soup up your brain a bit to make putting things together easier."

"Do I get to choose which or is it out of my hands?"

"Well, it's not going to be a minor divination talent if your magic system doesn't allow for them."

"Aww, no metanarrative shenanigans for me? Fair. Okay, so who's next?"

"No metanarrative shenanigans whose components don't have diegetic justifications. The last perk is Yuri Heroine, which does exactly what it sounds like."

"Ah yes. Crucial to my plans, that one."

"Highly. So the flaws are Abhorrent Admirer, Anything You Can Do, Dark Secret, Ditz, Equal Enemy, Ghost In The Flesh, In Character, Jealousy, Late Start, Magicless, No Compromise, Not A Fan, Patriarchy, Peggy Sue, Save The World, Sickly, Spoiled Rotten, There's Two Of Them, Unattractive, and Unprepared."

"There are so many of those that sound like I won't want them! But I will hear them out just in case."

"Abhorrent Admirer is like the Admirer minion, except that he's guaranteed to be useless to you, deeply annoying, and in some kind of situation where you can't just immediately make him go away."

"I will restrain the urge to pit my ability to choose to like someone against the scenario designers' ability to provide me with a really annoying admirer."

"Thank you for your restraint," the angel says seriously. "That is an arms race that could end unpleasantly. For other people who are not you."

"...what do you mean?"

"Unpleasant people are rarely unpleasant only to one person. Also, if the character-building team felt like they couldn't concoct a person you would dislike, they might move into the areas of downright hazardous." 

"I see. Yeah, overall probably best not to go there."

"'Anything You Can Do' means that literally every skill you have, the heroine will be better at it than you are."

"Every skill? What counts as a skill? Can the heroine flawlessly impersonate me? Does she love pretty colours as much as I do? Is her handwriting as cute? Is she equally moved by the romantic vision of being bound in servitude to her alleged nemesis?"

"Not unless your personality is something you deliberately constructed or are otherwise doing on purpose, no, she'll be able to write as cutely but may or may not choose to do, so, and no, respectively."

"Hmm. So it's more narrowly about the kind of skill you could be graded on or have a contest about? Does it also mean that anything I put effort into learning once we know each other, she'll get the same benefit for free?"

"No, but she's more likely to independently learn it, and she'll get better results from the same amount of effort as you."

"I think I want it. What's the next one?"

"Dark Secret! You, or your family, have some kind of secret that would be socially catastrophic if it got out. You get to pick the secret, but take care to consider how 'X is a catastrophically devastating secret' is likely to shape society, for any given value of X."

"Oh that sounds like such a fun puzzle though... I'm tempted but we'll see how things shape up once I'm starting to sketch out my world. What kind of time limit am I working with here, anyway?"

"If you spend so long here that you cease to communicate intelligibly, then I will finalize your most recent penciled-in options and send you on your ay."

"...hmm. Hypothetically, what would happen if I stayed here indefinitely while remaining lucid?"

"Then we would continue to converse, I suppose. The pocket dimension we're in is severely time-dilated, and I categorically don't get bored."
