No yeah she wouldn't ask Megi to stay.

...She guesses, uh, where should she send mail?

"...Hmm. There's a few places I'll probably get it eventually."

She'll write down about half a page's worth- Two notable temples, a merchant house in the south, and a few other kitsunes, Sinnah herself, one called Weiss, one called Lilia, and one named Katherine.

"Sinnah is very dedicated to magic and things that enable doing more magic, like money, or sex since that's the fastest way to get more energy to cast magic with. Lilia plays at being a noble lady and lives over near the City of Fire. Katherine is a homebody who lives down in Noten, in Greatcliff City. She runs an orphanage and school. Weiss recruits me to fight Cryptids occasionally. It needs doing. Though I have no idea where she is any given time, her house is near a village in the March of Flowers, also in Noten."

"Good to know!  ...I was thinking about asking if you knew Sinnah's mailing address anyway; I have a spell I really want to work out, because if it can be done it could upend diamond scarcity."

"Well, you have it now! That would be... Well, revolutionary. I hope it works out."

...Okay, one last hug, and then Megi will leave with all the best wishes for Alicia's endeavors.

One hug for the road, mhm.  Safe travels!

And thusly she settles in for University Education 2.0, Now With Magic.  ...She's not going to put her plans for artificial diamond manufacture in the mail until she can't progress them any other way, though.

Several Months Later...

She has been working towards this spell design for months.

For almost a year, even.

She just needs to find a way to refactor it that doesn't require her to write two runes on top of eachother.

Baby-kitsune neuroplasticity aside, English has better swears, and when every attempt to refactor this spell leads inexorably to a collision again, when the hypothetical 'rune convolution' technique she just spitballed might exist is very much not known to her... she really wants to swear at something.

"Motherfucking piece of shit spell structure, why the hell won't you cooperate with me, all I'm trying to do is replicate naturally-occurring real-world conditions...  Bloody hell.  I'm going to absolutely fucking lose it if I don't figure out how to work this."
