"I feel like it's bad incentives to have it work this way! Unless that many heroines would make the narrative too one-sided, or complicate the cast too much? But it's otherwise really sounding like I get to make the narrative as one-sided as I like so long as it's stacked against me... whatever, I shouldn't dwell on criticizing the creative choices at work here."

"So nobody involved in that kind of decision-making feels the need to explain things to me, but if I had to guess, the logic is that, on the margin, three heroines is less of a difficulty boost compared to two than two is compared to one, so a third heroine, while allowed as a voluntary add-on, wasn't deemed worth the flaw point. But I could be mistaken. I'm not sure how it would be bad incentives, though, since I'm confident the people in charge don't strongly care whether more people take two or three heroines."

"Look, the whole thing is clearly structured to encourage me to make my own life as difficult as possible. Which I'm down for! But it strikes me as a failure of imagination to expect that adding a third heroine won't be difficult enough to be worth paying me for. Assuming it's not just a genuinely ill-considered decision, I think it's got to be that they just don't want the game to have three protagonists, which, fair! That's a pretty tough narrative to pull off!"

Shrug. 

"I'm not sure if I should refrain from getting into this because I really don't have answers and it's not important, or share the insights I do have."

"Leave it for later, I want to get through the list. We'll have plenty of time to chat about inconsequential things when I'm wringing out my brain for everything I've ever learned about magic so I can incorporate it into the worldbuilding."

"Reasonable. Although, actually, I can conjure arbitrary reference texts from your world, you don't have to personally remember everything. Ordinarily I would say you didn't even need to have all the information, I could just tell the worldbuilding team to copy your magic system wholesale, but that would help less with the part where you actually write the visual novel."

At the words 'arbitrary reference texts', her eyes take on what you might call a deranged gleam.

"Oh, I am going to have so much fun. —list first, list first. And of course I don't want to copy my magic system wholesale, I want to improve on it! I want to get creative! List first though. List first and then I go mad with power."

"Next to last flaw is called Unattractive. You can customize the results of this to some extent; if you want to keep the face you have now, and that face is just considered very plain by Villarosa's standards, that works, but the flaw categorically cuts you off from pretty privilege for the duration of the plot."

"I feel like that would be thematically at odds with my desired narrative."

"Yep. The last flaw is Unprepared. That wipes your memory of this encounter and makes it seem like you just isekaid into a preexisting fictional narrative from your original world; take Not A Fan and you won't have any meta-knowledge at all."

"Oooooh that's so tempting. That's so tempting. You have no idea how tempting that is. It'll make my desired narrative so much harder to achieve, though! I'll think about it."

She rubs her hands together.

"Okay. Arbitrary materials, you say? Please summon me your very girliest notebook. It's time to get organized."

"I can't actually execute superlatives like that; I have enough creative control that, no matter how girly a notebook I summon, I could come up with a girlier design later." But she summons a very girly purple notebook. 

"The superlative need not be literal." She opens the notebook and absently pulls a pen out of her pocket to start jotting down notes.

Oh, I recognize that handwriting! Hello again! ♡

Fancy meeting you here! Do you know anything about this Villarosa nonsense?

All I know is my next recipient is here but they aren't you.

Well I happen to be trapped in a mysterious otherworldly space with a very nice lady who I hope will have a wonderful time meeting you. She's supposed to be guiding me through a series of choices relating to a romance storyline I'm slated to appear in, but maybe I'd better let her be the one to explain the rest. One moment. ♡

"--Sorry, what?" she accepts the notebook, blinking. 

The notebook's conversation with Rosy is there on the first page, Rosy's parts appearing in the plain blue pen she was writing in, the notebook's parts appearing in different handwriting in sparkly purple ink.

"So funny story, before you and I met, I had an encounter with this notebook in a mysterious void and she guided me through a series of choices that gave me fantastic magical powers. I guess I'm just having that kind of day."

"I...didn't requisition a magic notebook..." she peers down at the lettering. Rosy absolutely seems like the kind of person who would be able to fake a second set of handwriting like this; the different inks are odder but she didn't look very closely at Rosy's pen and there are pens that can do that. "In fact, I can't requisition things that are people into the time-dilation."

"I expect this notebook is not affiliated with your usual requisition system. Go on, say hi. I don't think she can hear you, just see what you write in her."
