Spoilers: Natsume does not meet her maker by Hugin’s hand this week. Instead she’s saved by two things: Hugin’s momentary distraction with the new Gadoll bug, and Kabu managing to log back in as the orange Gear and shoot Hugin through the chest, thus logging him out of Deca-Dence. It’s a bit convenient and plot-armory, but fine, it’s not like I wanted Natsume’s story to end in that trailer.
After that, Natsume must quickly wrap her head around the fact that the Boss she knows who is lying dead on the ground is just an empty avatar, and the Boss himself is in the orange Gear body. Minato’s crew determines the massive Gadoll to be a bug that survived the GGS. The System designates it Gadoll Omega, and orders Deca-Dence to take it out.
But while this Gadoll bug isn’t that much larger than the largest Gadoll they’ve fought and defeated in the past, it’s much tougher, not only absorbing Deca-Dence’s fist blow in its crab-like claws, but shoving Deca-Dence back, doing critical damage to its movement apparatus. When Solid Quake’s orbital HQ uses its Solid Cannon from orbit, the Gadoll meets that beam with its own red one…and wins.
It’s the first time we’ve seen the pristine Solid Quake HQ ship damaged, and it’s enough to spook The System into pure Self-Preservation Mode. To that end, the entire Deca-Dence program is being shut down. Hugin is replaced by Munin, who politely announces to Minato that all Deca-Dence facilties are to be reverted along with Omega via the spacial decompression device—a fail-safe in case the game ever threatened the System.
Suddenly, there’s six hours until the end of everything on the planet surface, including what remains of humanity. But Jill, reestablishing contact with Kabu, says there’s still a way for a user to log in with Deca-Dence itself as their avatar. She knows this because prior to being designated a bug, she helped build Deca-Dence’s core.
Kabu and Natsume go their separate ways, but Natsume assumes they’ll meet up again at some point, while Kabu is ready to not return, as he’s volunteered to take the reins of Deca-Dence. His jeep passes Natsume, marking the first time she’s seen his cyborg form. Of course, she only gets a brief glimpse and has no idea it’s him.
At the epically huge and cool-looking core, Minato confronts Kabu, telling him there’s still time to run, to which Kabu asks where to? When Minato admits he has no idea what he should believe or do anymore, Kabu tells him he was once the same way, and simply waiting to be scrapper, until he met Natsume the Tanker Bug, who taught him he can make his own choices.
Then the best thing ever happens: Natsume meets Kabu’s cyborg comrades…and after a few moments of profound confusion, accepts it, finds them adorable, laughs, and introduces herself. Now Jill sees why Kabu has gone so far for a human bug’s sake. Jill herself has a bug still within Deca-Dence she’s hoping will make a difference.
Minato decides to help Kabu log in as Deca-Dence after all. While it’s true Deca-Dence is an absolute wreck, perhaps being under Kabu’s direct control (rather than the System’s) combined with Jill’s surprise bug, could conspire to unlock heretofore unseen abilities.
They’ll need everything they can get in the forthcoming finale, as the twin existential crises of the still-evolving Gadoll (and its brood) and the countdown to self-destruct will both have to be dealt with if anyone is to survive.
