Between the belated Dr. Frank backstory episode and the week off that followed, we’ve had to wait an awfully long time to get back to the central story of Hiro, Zero Two, Ichigo, and the others. Thankfully, it was worth the wait. This week starts in the Birds Nest, Squad 13 still shaken by the forced memory loss of Kokoro and Michiru.
Hiro and Zero have agreed to implant Strelizia into Star Entity, the weapon at the bottom of Gran Crevasse, in order to have a decisive edge against the Klaxosaur scourge. The couple only agrees reluctantly, telling APE that it will be the last time they call them “Papa” and let them steer their destiny.
Meanwhile, Kokoro is also she’s throwing up all the time, which is a pretty good sign that she’s preggers. That child may well prove to be the most important ray of hope for humanity, yet neither parent knows it exists, or remembers conceiving it.
Zero has also become one of the 13th again, defending her comrades against barbs from the Nines and really steaming Alpha’s beans. Once all the FranXX are mobilized the battle against a massive Klaxosaur force commences. In the middle of battle, Michiru calls Kokoro “Kokoro”, and gets a jolt of pain that spreads to her head and immobilizes Genista.
While Hiro and Zero descend to the bottom of Gran Crevasse, they commit themselves to the shared goal of being together forever. When this is all over, Zero hopes to travel the world like the princess in the story; it doesn’t matter where, as long as her Darling is with her. And should they ever be parted by outside forces, they’ll come and get one another, sealing the promise with a kiss.
With Dr. Franxx and Hachi along for the ride, Strelizia reaches the bottom, but when Strel reaches the portal to Star Entity, it won’t open, and the Klaxosaur Princess (whom Franxx calls Zero One) bursts through the walls of the Crevasse, intent on stopping the humans from stealing her “child.” The Princess forces open Strel’s cockpit, yanks Zero Two out, and restrains Hiro.
After giving him a very rough and not very romantic kiss, the Princess takes control of Strelizia, not needing the stamen-pistil interface (I like how she just floats around with arms crossed like a boss). Hiro is helpless to resist, but a wounded and bleeding Zero Two starts a slow and arduous journey back to her darling, to fulfill her promise.
As the princess links up with Star Entity, to form “Strelizia Apath”, Dr. Franxx tells Hachi about how Klaxosaurs split into two distinct forms: the magma energy that courses through the depths of the earth, and a form that consumed that energy and took physical form. He also reveals that Klaxosaurs are biological weapons built and piloted (in male-female pairs) by “klaxo sapiens”, a species of which the princess is the last surviving member.
If that sounds like how FranXX are piloted by parasites, it’s because the FranXX are themselves Klaxosaurs that genetically-modified humans can use. This confirms that most if not all of the Klax Squad 13 has fought and destroyed had pilots just like them.
There’s one more big reveal: APE is led by members of an alien race known as the VIRN, whose objective was to retrieve both Star Entity and Hringhorni (a spear made of Klax cores) for use in space as “soldiers”, i.e. tools. Now that the princess is threatening that, they decide to destroy both assets and the rest of Earth with them.
With that, a massive space fleet appears just past Earth orbit. The Princess activates Apath’s main weapon, obliterating much of the fleet in a dazzling show of lights an kick-ass space battle sound effects. Don’t get me wrong, it’s a lot to take in all of a sudden, but there was always something alien about APE, so it’s not like all of this is coming out of nowhere.
We even get to see a VIRN’s true form, a four-pointed star-cross with eyes. Maybe not the coolest or scariest design (and more than a little similar to Eva-explosions), but definitely weird and alien.
Turns out they booby-trapped Strelizia Apath, rigging it to explode if the Princess ever piloted it. As she is restrained by glowing VIRN-purple bonds, they start to infect Hiro as well, but he still can’t move, and even if he could…what could he do?
I have no idea how Hiro and Zero Two are getting out of this one, but they’re both alive for now, Zero is still coming for her Darling, and there’s four whole episodes left; plenty of time to craft a satisfying final denouement.
