As the elevator to Brother and Sister’s destination rises out of the debris, Hoodlum reunites with the others, proudly reporting to have stabbed the Apprentice to avenge his brother, Brawler, who didn’t make it. When Brother is flippant about there being casualties on the job, Hoodlum almost loses it, but Swindler once again plays the peacemaker, and his temper subsides.
At the end of the elevator’s descent they reach Expo Park, a sprawling abandoned underground amusement park. Bunny and Shark cut in to tell us it was built before the war to preserve the culture of Old Kansai, but ominously notes that “there are some things better left not known”. The siblings’ ultimate destination is a rocket that Brother says will convey him and his Sister to a base on the Moon, where they’ll be safe.
That’s when we learn from Brother that he and his sister are the result of human experiments at Kyushu Plant to create immortal humans. Between them they are the product of 5,555 other siblings who were sacrificed in one horrific way or another to make the two of them possible.
I’m reminded of any number of anime in which humans and innocent kids in particular are treated brutally by an unseen, unfeeling scientific villain. Brother wakes up in a lab in a puddle of blood that grows bigger and bigger until one day the gym once full of siblings is empty.
That’s when the “Headmaster” reports that he was a successful experiment. They go on to make one more, Sister, and the two of them will be sent to Kanto as an “offering”, with mass production to follow. But their “Professor”, an AI in an artificial cat body, took pity on them and allowed them to escape on the Shinkansen. The rest of their story we know.
With that, Brother deposits a billion yen in each of the surviving Akudama’s accounts and deactivates their bomb collars, and prepare to board the rocket. Swindler gives them a farewell hug with the wish that maybe someday they’ll see each other again and eat more yummy takoyaki together.
Then, as the siblings ascend to the rocket’s hatch, Sister is stabbed in the throat…with one of Doctor’s scalpels. She’s fine, but she grabs Brother, making her meaning plain: she’s sold them and everyone else out to the Executioners.
A huge contingent of them suddenly swarm the launch pad and surround the Akudama. When Swindler asks Doctor why, the Doctor coldly declares she doesn’t owe her or anyone a goddamn thing. In exchange for her delivering the “offerings”, Boss removes Doctor’s Akudama status; she’ll no longer be on the run. Boss also tells Brother that the “Moon” they see in the sky is a mere holo-illusion; the real moon was destroyed in the war.
Brother bites Doctors hand and breaks free, while Courier and Cutthroat fight off the swarming Executioners—the latter particularly concerned with Swindler’s safety. He gets cut up pretty bad (which spells trouble considering their medic has defected) but ultimately ends up buying time for Swindler and the siblings.
Brother takes hold of Swindler and leads her and Sister into the rocket just as the countdown reaches zero. The rocket successfully launches with Swindler and Sister inside. Brother probably feels better to have at least protected half of the 5,555 siblings who died for them than none at all.
As for where the rocket is headed, who can say? The episode ends with it trailing away from what’s left of the moon—though perhaps its course takes the earth’s rotation into account. Even if they reach the moon, there surely isn’t anything there but death…but that wouldn’t be any different from the Executioner-infested launch pad.
First Hacker split off, then Brawler died, and now Doctor has stabbed everyone in the back. It remains to be seen if the Executioners either claim or scatter the remaining team of Courier, Cutthroat, and Hoodlum. Much like the war shattered the moon, the show has blown its group dynamic to smithereens. We’ll have to wait and see where the pieces land.
