"I can include arbitrary Earth instrumental music but anything that requires cultural context to make any sense has more limitations." 

"Do please include Beethoven."

"I'm not sure I want everyone to be laughably naive but I'm not sure I don't, either. Depends how hard a time we're going to have if they aren't."

"And Bach. Chopin. Mozart. Um...Heinrich Schutz and Giacomo Carissimi...Handel and all the other less famous Bachs...let's just take all the Earth music as instrumentals and call it good." 

Pause. 

"I'm not necessarily in favor of everyone being laughably naive but, like, I am willing to have it be the case in exchange for concessions. Like pausing this until I can have my people."

"So let's assume for now we're going with a high-magic space opera where our parents' generation was created from nothing by the remnants of a fake ancient civilization, with exact levels of widespread naivete to be determined when we're farther along in negotiations. What else is there to decide?"

"What hairstyle, hair color, and race each of you will be; which of you will fulfill each of the three 'villainess' roles and have each of the three assigned arranged fiances for the heroine to potentially seduce; what your fictional counterpart's 'canonical' bad end will be, which of the three available roles your heroine will occupy, and what minions, perks and flaws each of you will select." 

"Why hair specifically...?"

"Because video game art is often less than ideal in terms of other identifying features."

"Can I not keep my current hair? I like my current hair." (It's long and dark and curly and, in fairness, very pretty.)

"It's not that you can't keep your current hair, it's that in order to keep your current hair you have to make mechanical choices compatible with your current hair. The hair color options are blonde, redhead, silver, brunette, and rainbow; the style options are drill hair, hime cut, and 'elaborate.' You can either tweak drill hair to be slightly less absurdly ringlet-y or make your hair be the same except about eight feet long and take elaborate. For color, you would have to take brunette. Drill hair gives you for free the perk 'Ohohoho!'" she does the anime noblewoman laugh hand gesture as she says the name, "Hime cut gives you the perk 'Silk Hiding Steel,' and Elaborate hair gives you a free maid minion."

"What, dare I ask, are the mechanical effects of," she mimics the hand gesture, "'Ohohoho!'?"

"You gain the ability to deliver the villainess laugh on command, and something about it is almost--or depending on the setting, maybe actually--supernaturally intimidating, striking dread into your foes and encouraging your minions. You will be a much more feared and imposing person, and even the heroine will hesitate to directly confront you."

"Ohohoho," Ghys says dryly. "How about Silk Hiding Steel, what does that do?"

"You gain a core of inner strength and determination beyond what you currently possess that will serve you well; setbacks won't faze you for long, and you'll always be able to keep your cool and act decisively in violent situations, even if you aren't trained for such things."

"See, I want that but—I have no idea what a hime cut is—if it involves straightening my hair, I'm not doing it. Can we trade our free haircut-related perks somehow? I have a feeling Ghys would enjoy the supernaturally intimidating laugh but her hair is already straight and it looks very nice that way."

"A hime cut is straight with bangs. You can't trade in your hair perks but you can purchase them the normal way."

"But what if I smile at you very charmingly, then can we trade our hair perks?"

"Alternately," says Naomi, "what if I make the case that my preferred hairstyle suits my preferred perk on an aesthetic level?"

"If you want to make an argument that your current hairstyle qualifies as a hime cut, I don't expect you to succeed but I welcome you to try. If you want to argue that Silk Hiding Steel is aesthetically suited to a non-hime cut hairstyle, I won't forbid you from doing so, but it won't do any good. I don't have the authority to make mechanical changes like that; if I try, one of my superiors will call shenanigans and change it back." 

"I still don't know what a hime cut is so I don't expect to have much luck convincing you I have one... hmm. What, if anything, prevents me from changing my hairstyle once I'm reincarnated?"

"First of all, good luck getting naturally straight hair to do that," she gestures at Naomi's glorious mess of curls. "Secondly...you know how sometimes you know that in theory you could do something, but that fact has no bearing whatsoever on what you actually end up doing?"

"...well when you put it like that it just sounds like a challenge."

"I'm not saying it's impossible to do, just unrealistically psychologically difficult."

"Anyway I was thinking of specifying that my, I don't know what to call it, backstory self I suppose, has naturally curly hair which she's in the habit of straightening. And then when I get control of myself I can stop."

"This is more thought than I was planning to put into my hairstyle, but—what's the phrase?—you do you."
