4 minutes into the episode and we get the scene I was waiting for.... Bilac totally freaking out at the Gold Crystal Scorpion Parts
One picture isn't nearly enough to convey how shocked Bilac was. She actually dies from shock and now Sunraku doesn't have an ancient craftsman anymore, hence the "Despair" in the episode title.
Okay, just kidding. Bilac's fine. The aforementioned "Despair" is because Sunraku cannot equip any of the sci-fi armor in the Inventoria due to Lycagon's curse mark.
It makes me wonder if Bilac might make Sunraku a sci-fi helmet or something. Either way, Sunraku is super bummed out about not being able to use sci-fi suits in SLF. To get over it, he does the next best thing: plays another game with Sci-fi suits: ~~Armored Core 9~~ Nephilim Hollow.
For an isekai, it's amazing how many different games we see aside from the titular Shangri-La Frontier. I'm sure some piece of information from Nephilim Hollow will become relevant to SLF.
Be sure to watch the SLF Minis after the credits (there's two). They're both good, although the second one reminds me of a joke from How I Met Your Mother.
