Natsume happens to be thrust into her first battle by no fault of her own, but there’s no way she’s just going to stand around and watch. She borrows some tank gear and runs into the thick of it. Even when a Gadoll impales one of her fellow fighters and blood splatters everywhere, she heads towards the danger. Like a soldier. This is your place and time, a voice must be saying in her head. Don’t let it go to waste.
Natsume darts around the battlefield with aplomb, Taking every single stitch of training from Kaburagi and making full use of her brand-new arm cannon. She’s too busy to be afraid to die; she can die when the battle’s over; when her time is up, something she’s always known is something she can’t control, only maintain.
She really shows something out there, such that the other Tanker fighters and their illustrious leader Kurenai takes notice. When Natsume tells her she’s not technically “in” the Power because she’s a “bug”, Kurenai laughs off the self-deprication. If Natsume’s a bug, her two lieutenants are boogers.
Kurenai warmly welcomes Natsume to join the Power and her unit if she so wishes, and of course Natsume very much wishes, being sure to thank her boss, without whom she wouldn’t be there. Kaburagi, who is just trying to keep Pipe out of sight, gets accosted by Kurenai, who remembers “Kabu-san” when he was on the front lines and has a huge crush on him.
Natsume would seem to have joined the fight at an auspicious time, when the largest battle in Deca-Dence history is about to take place. Gear scouts have discovered the main Gadoll nest, and Kurenai’s Tanker squad is being given the toughest and most important job. They’re to defeat “Gadoll alpha”, a monster creating a cloud of fog across the nest. With the fog gone, the Gears will be able to easily mop up.
While touted in-game as the ultimate epic final battle that, when won, will finally enable humanity to live in peace, back at Solid Quake Kaburagi learns from a friend that the arc will result in a crushing defeat for Deca-Dence and massive losses. Those tragic developments will pave the way for the return of “legendary heroes” to save Deca-Dence in its hour of need.
One of those heroes is Kaburagi himself, who is being pulled out of his chip-collecting retirement as a result of rave reviews of his unplanned return to the battlefield back in the first episode. When Kaburagi told Natsume to “make sure not to die”, he was telling her to be careful. But now, if she participates in the battle she’ll die for sure. And since she’s human, she won’t come back.
Natsume meets Mindy, Mundy and Mendy, triplets who are, other than her, the youngest members of Kurenai’s unit. She makes a bad first impression when Mindy tries to shake Natsume’s artificial right hand and it accidentally transforms into a spear launcher.
Mindy is livid, warning Natsume that going into battle with a weapon you haven’t mastered is no different than begging for death (her siblings think she was too harsh.) Back in her neck of the woods, Natsume sees her friend Fei, who has decided to wash her hands of Natsume. Like Mindy, Fei sees Natsume’s disability as a disqualifying attribute. If she tries to be a soldier, she’ll just die.
Having had those encounters, you can imagine Natsume is decidedly not in the mood to have someone else tell her she can’t do what she wants to do, and is pleasantly surprised when Kaburagi knocks on her door for a change. She offers him milk (no doubt a rare delicacy), but he’s come to warn her not to join the battle tomorrow.
While we know full well Kaburagi is dissuading her for the right reason (she may well be ready, but the battle is literally rigged), Natsume assumes he’s once again joined the ranks of the naysayers. He can’t tell her the truth about why he knows, because that would be opening a whole other can of worms. So Kaburagi goes full “bad guy” and breaks her Tank. She may live to hate him, but she’ll live, and that’s what matters.
The spilled milk and oxyone pooling together on the floor was a really cool and effective symbol for the split worlds of Kaburagi and Natsume, as well as their oil-and-water difference of positions.
Natsume approaches Kurenai to tell her she’s sitting the battle out. Kurenai is understanding, but wants Natsume to be sure it’s what she wants. When asked why she fights, Kurenai states worthiness of Kaburagi to be one reason, but also because living her days aimlessly in a cramped dirty metal box just isn’t for her.
As she skulks home, Natsume remembers feeling the same way as Kurenai, even as an adorable little kid. Her father would show her amazing sights of the outside world, and told her they’d be able to visit them when peace was achieved. She came to believe she’d be the hero to end the war, but after she lost her arm, and got told all the things she couldn’t do, that belief waned.
As Natsume tells Kurenai after changing her mind and declaring she’ll join them after all, she doesn’t like the way she is right now, and wants to change it. She wants to change into the fighter and the hero her younger self dreamed of being. She just needs to borrow some money to replace her tank! And then, of course, not die.
But hell, even if Natsume knew and believed everything Kaburagi knew—about cyborgs usurping humanity as the dominant species on earth, about how every aspect of her and every human’s life is manipulated by a corporation—she may well still decide to fight. This week’s episode made it clear this is her story, and her choice. And if she existed outside the system as a “bug” this long, not even Kabu-san knows how far she’s capable of defying that system.
