Just curious if you wanna tag along. You're pretty neat. No obligation or anything, just fond of you. 

I do sometimes tag along with a vessel of the Spirit, and you all seem pretty neat too, but even though I'm a little torn about it (so to speak), I think I'd rather not. ♡

Absolutely valid. 

Okay, this is it. Can you finalize our builds when I drum on your cover? —Does it bother you if I drum on your cover? The basic idea is to take us and the backpack we'll be carrying — can we take things with us like a backpack? — when I give you some kind of signal, that way I can give a little speech on camera, drop something I'm fiddling with between my fingers, and signal you before it hits the desk. The video will stop ten seconds later and go where it needs to automatically.

Yes, you can take a backpack with you, yes, I can finalize your builds when you drum on my cover, and no, it won't bother me. ♡

You're a treasure, notebook-friend. We're so glad to have met you. Thank you for everything. ♡

Okay, packing things up now.

She puts her purple pen away in the backpack, slips it onto a shoulder, and closes the notebook. She tweaks the upload script to have a two minute delay, that way she can cancel it if nothing happens and she doesn't disappear. Then she grabs a random basic pencil and starts twirling it between her fingers, then holds down the spacebar with her left hand, starting the recording. The clock ticks away in the background, visible over her shoulder.

"Hello everyone. Family, friends, something deeply improbable happened to me. I got offered an isekai, a trip to another universe. I'm getting magic powers, the body of my dreams, and so much more. Naturally, y'all won't believe this just from my saying it, so I've arranged things so I can disappear on camera. This video will go to everyone I've thought of. If anyone else is worried about me, feel free to share it. Also feel free to send scientists to investigate the spot where I vanished, just in case they can learn something from it.

"This is an opportunity I can't pass up. Love y'all. Bye."

She flips the pencil into the air just high enough to give her time to wave, twirling her fingers in a playful wave to the camera, and takes her finger off the spacebar to drum her fingers atop the notebook's cover.

She's gone before the pencil hits the desk, the impact audible in the recording. The empty seat is recorded for a few more seconds, clock ticking steadily in the background, and then the recording stops.

Two minutes later, it gets uploaded to the discord server where her friends hang out, and to a file server where it can be sent to her parents and sisters.
