When Jill tells Natsume that Kaburagi has connected with Deca-Dence to become Kabu-Dence, Natsume is momentarily bewildered by her Boss’ constant changing forms. But change is at the heart of this episode, and ultimately the salvation of free cyborgs and humans both.
Everyone rallies behind Kabu and Minato, with the Gears logging in en masse to participate in the game’s climactic “Final Mission” while Donatello fills in Kurenai and the Tankers.
Minato and Jill are concerned that despite a successful connection, Deca-Dence isn’t doing anything. That’s because Kaburagi first has to deal with something very similar to Neo in The Matrix Reloaded when he meets The Architect. In this case, it’s The System itself, telling him that even bugs are a part of the system, meaning anything he does will be within the System’s calculations.
But if that were the case, why try to stop him? Kabu doesn’t buy that cog-in-the-machine crap anymore; he’s living his life by the precepts gained through Natsume: push yourself to the limits in order to help create a better, freer world. With that declaration, and Natsume simultaneously smashing her arm to pieces “waking” Boss up, Kabu-Dence finally stirs to life.
With glowing tendrils it reaches out at all the hunks of debris throughout its surroundings, which were brought back to life thanks to the Gears and Tankers topping them off with oxyone. To Kabu’s distress, one of the people helping is Natsume, initially trying to push a huge part all by herself before being joined by Kurenai and her Tanker comrades.
With less than ninety seconds until total spacial displacement, Minato orders the now charged and upgraded Kabu-Dence cannon to fire upon Gadoll omega, the beam of which Donatello deflects by sacrificing his Gear avatar. It fires, and there’s a big boom but…it doesn’t work. The beam wasn’t strong enough to break through omega’s adamantoise-esque shell.
With under forty seconds on the clock, Kabu seems resigned to oblivion…until stored memories of Natsume’s best and most formative moments flash before his visual interface. Natsume herself was drawn within Kabu-Dence’s machinery, and her presence seems to snap Kabu out of giving up.
Kabu-Dence’s limiter is suddenly removed, enabling a far more powerful attack even with the oxyone stores depleted. The blast is enough to destroy Gadoll omega, but completes the destruction of Deca-Dence as a mobile fortress in the process.
Whether due to the strain of the limit break attack or damage to his body caused by falling debris, Kaburagi concedes that his time has finally come. The System was right about one thing—that he was going to die either way. Left out of that statement is the fact he wouldn’t die until after he successfully broke that system, with the help of his friends.
When Natsume finally finds Kabu’s cyborg body, his face is broken and the one light remaining behind is about to go out. Natsume lets some tears fall, but she doesn’t lose it; she merely expresses gratitude to her boss and assures him she’ll be okay on her own from now on. He gave her and every human and free cyborg a chance.
Three Years Later, and Deca-Dence is now a bustling city surrounded by verdant farmland, where humans and cyborgs peacefully coexist. Under “Supreme Administrator” Minato’s leadership and Jill’s scientific prowess, the game has changed: no longer a brutal battle in which Tankers were cannon fodder and servants, now cyborgs share in the labor and betterment of the new civilization beside their human friends.
Natsume has started a business taking cyborg tourists out on exploration and adventure trips. Her new arm can become a helicopter rotor, which is pretty awesome and also makes her a kind of unique conduit between the human and cyborg experience. As she promised, she made a life for herself and thrived without boss around. But that doesn’t mean when Jill eventually manages to bring Kaburagi back, using his backup data and a new avatar body, she isn’t glad to see him again!
It’s a fast, focused ending and the epilogue-over-end-credits is perhaps a bit rushed (I’d have loved to spend more time in this lush, just new world). But seeing Natsume’s face light up once more as she recognizes him emerging from the glaring sunset is as fitting image as any on which to close the book on the tremendously entertaining and unflinchingly relevant Deca-Dence.
