Back when New Tricks came out, I said that it felt like a return to the older, more episodic Eyrie Productions, where UF!Gryphon stumbles headlong into one anime after another? This kinda does the same thing in a different way. Think all the way back to the beginning of Undocumented Features: the divergence point, the event that kicks it all off, is the accidental creation of an artificial intelligence. This is much more narrowly focused, and it doesn't show any sign of leading to another complete retcon of galactic history stretching millenia into the past, or to the destruction of Worcester, MA, but the parallel still made me smile a little.

We haven't really seen that much of Earth or galactic society immediately post-contact, have we? There's this, there's the mini about Zefram Cochrane testing the hyperdrive he's independently reinvented, there's the first story featuring Redneck (which IIRC introduces Zardon), and there's been a lot of hints at things that happened but not actually onstage, but I feel like FI-era is much more fully realized. The variety is nice.

On a more out-of-universe note, the extent of my prior exposure to Vocaloids is that someone I follow on Twitter went to a Magical Mirai concert in 2015 and posted a whole bunch of photos with no context. I then tried to find examples of the music, found the really old stuff that sounds like it's been AutoTuned to death, and gave up. :-/ So I also want to say that you have once again done an excellent job of presenting new-to-UF characters to people more-or-less completely unfamiliar with their source material, and that I appreciate your choosing sample music videos based on newer iterations of the software. :)

And finally, when y'all first used the line "My friend, don't be a dick," it seemed such a perfectly Venkman thing to say, so I was pleasantly surprised to see it fit neatly into two other characters' mouths in the course of the same story.
