I love this chapter.
Dunno why everyone was worried about the cat, though. They're halfway to eldritch beings even without the extra eyes and four-story building dimensions. Worst thing about this one would be the food bill.
Interesting that Aru shrugged off that firepower; I suspect that means she herself is constantly changing, since System should have constantly-updated information about her physiology and their weaponry would, I'd imagine, reflect that data for "emergency cases". That, or even their best efforts just cannot match her, and she's a singular entity that's wholly different (and above) everything else the Holes can produce. (Since the Cat was afraid of her too, I suspect Aru's just on an entirely other level.)
Her thinking constantly about and planning through their future together was cute, too. No idea how much any of that would actually transpire, but it's nice to have dreams, even if you're an apocalypse in human skin.
Thanks for the TL.
