We left Nagate in a very bad, but at the same time very sexy way, with placenta in the precise form, sound, and probably even smell of his first love Shizuka, whom he’d once shared a very meaningful period of time while stranded in a cockpit. But the senses are deceiving; this is not Shizuka and never was, it’s a predator, and she looks primed to eat him.
Or…well, do something with him. The French kiss she/it initiates, and the whole slow pace of her attack on Nagate, suggests something other than mere feeding. She’s taking her time with him, restraining him, and about to become one with him; I wouldn’t be surprised if this is Benisuzume either conducting an experiment of her own or something built into her genetic profile.
In any case, Beni didn’t count on Izana being inside Nagate’s frame. She’s able to use her bionic arm to activate aux power and close the neck airlock, separating the Shizuka placenta from the rest of Beni and releasing Nagate, who stabs her in her core, causing not one but two of those sweet, sweet bubble disintegration sounds that tell you a Gauna’s gone for good.
That’s not the end of this decisive battle, however; Planet Nine remains a battlefield, and Nagate, the crippled Tsumugi, Izana, and whatshisname are soon surrounded by seemingly all the Gauna on the planet. Nagate prepares for another last stand, but he’s bailed out by a cavalry of Hayakazes led by Samari, who have finally arrived in orbit, one hundred strong (grouped in 25 Hayakazes). As Nagate and Tsumugi serve as bait, the rest of the planet’s Gauna are mopped up with overwhelming firepower.
It’s a great feeling when that last Gauna disintegreates, but due to the nature of this show, it never felt quite right to let my guard down until everyone was back aboard Sidonia, and even then, there could have been some ginormous ship-to-ship battle in space to close us out.
Instead, Nagate (with a still-alive nude Placental Shizuka in his arms) carries Tsumugi and launches away from the planet to join the Hayakaze squad, and they return to the mothership without incident.
With the titular Battle for Planet Nine won, the balance of the episode, and perhaps the Sidonia series, is spent in Epilogue Mode, similar to the last episode of UBW. Nagate is awarded a medal (the first awarded in decades) by Kobayashi in order to continue building him up as the Great Hero to inspire the rest of the soldiers; there’s a party where the Honoka clones cluster around Nagate to Izana’s disapproval.
Nagate asks what’s become of the new Placental Shizuka, and Kunato tells him she’s being treated as a valuable specimen for further research, citing “important things must have a spare.” The march of “progress” goes on, and I imagine it also entails one day creating a spare Nagate.
The series then ends where it began, which I thought was a nice touch (though my one major gripe about this finale is that we didn’t get to see any more Izana after that awards ceremony). Nagate hadn’t just come a long way in becoming a decorated, respected, and fawned-over pilot and war hero; he also came a long way geographically, as the same journey through the bowels of Sidonia from his cloistered domicile to the rice thresher is played in reverse, only instead of an urchin on the run for theft, he has an entry pass and is welcomed with salutes once the staff knows who he is.
Nagate inspects the simulator his grandfather and him used to learn how to fight Gauna, giving him the tools to make a contribution to society should he leave the confines of his sheltered home. He did, and he doesn’t regret it. He’s seen and done amazing, extraordinary things with a host amazing people of all stripes.
Yes, he’s still technically a pawn of the junta, but that doesn’t change the fact that he’s a Knight of Sidonia, who will keep fighting to protect his home and its inhabitants until he draws his last breath—or at least until his new-and-improved Chimera replacement takes over for him!
As for me, I shall deeply miss Sidonia’s dark, gritty, sexy, terrifying, and always gorgeous and impeccably-rendered sci-fi milieu. From the start it’s reminded me of the rebooted Battlestar Galactica, only it managed to maintain the mystique of its primary foe (the Gauna remain alien and terrifying by the show’s end; the Cylons, not so much). Sidionia told and showed us a lot, but never too much; it’s deepest mysteries remained so through to the end.
I really wouldn’t mind a third season, or failing that, a Blame! anime, a peek of which we saw on Nagate’s TV. I want this style of anime to continue.
