Courier, Swindler, and Sister leap off Executioner HQ in pursuit of the helicopter carrying Pupil, Guy Pupil, and Brother. They’re headed to Kansai Station to put the kid on the next Shinkansen. Doctor is also headed there aboard a flying bus whose other passengers she murdered, with a terrified Hoodlum thoroughly wrapped around her little finger.
While en route, Pupil, Guy Pupil and Brother watch a newsfeed showing that the civil unrest has intensified, with large mobs ready to storm police and government buildings.
Courier, Swindler, and Sister learn of the extent of the unrest firsthand when their path to the station is blocked by a civilian-established checkpoint. Unfortunately for these intrepid vigilantes, Boss straight-up strong-arms the ineffectual police chief to declare all rioters to be Akudama.
This has the unintended side effect of allowing Courier, Swindler, and Sister to pass through the checkpoint, as the police bots begin arresting the civilians. As the bus flies over the hotel where he and Brawler had so much fun, Hoodlum wonders just what the hell he’s doing.
Armed with police authorization, Boss sics her Executioners upon the mob, resulting in a bloodbath she deems necessary to restore law and order in Kansai; her primary concern is how this reflects on her to Kanto. Courier reveals he always knew Swindler wasn’t a real Akudama until she became one, which makes her happy.
Then it starts to snow much earlier than is usual in Kansai, almost providing a little bit of hope and cheer to an awfully tense and uneasy situation for all involved parties…except Doctor, who doesn’t even look up to see the snow.
Pupil and Guy Pupil arrive at the station and enter the elevator just as Courier railguns through the doors. He manages to blast his way down to the platform, but by then the Shinkansen has arrived and Brother is in a cargo vault on its way to the train. That’s when Doctor appears and things get way more complicated and intense.
With the quickness of a cat she sticks Guy Pupil straight through the heart with a needle to make a “string of life” that she holds in her hand. Since she’s still not technically an Akudama anymore, the Executioners can’t touch her. Doctor uses that immunity and the string to force Pupil to go grab Brother for her.
Hoodlum, still thoroughly in Doctor’s thrall, holds a scalpel to Swindler’s carotid artery, while Doctor gasses Courier. She revels in having the lives of everyone around her in her hands, but underestimates the “nauseating woman” Swindler’s gift of gab.
By talking to Hoodlum about Brawler and their mutual respect and love for each other, and how disappointed his big bro would be to see him now, Swindler is able to get Hoodlum into lowering his scalpel. Doctor, in turn, is disappointed that Hoodlum is now useless to her, and brings up the fact she stitched Brawler up so he’d bleed to death.
Doctor orders Pupil to execute Swindler and Hoodlum, but before she can bring her lightsaber down on them, a revived Courier shoots it out of her hand. Then things get even more chaotic as this entire standoff is crashed by hundreds of rioters who broke into the station to pray before the sacred Shinkansen for salvation.
In the ensuing confusion, Hoodlum pounces on Doctor and slits her through “just like she taught” him, though she’s still able to slit his and whip out her emergency surgery tools. Only this time it doesn’t work, as the Shinkansen seemingly answers the rioters’ prayers and opens its doors for them. This starts a stampede, and before Doctor can stitch herself up, she’s trampled to death.
The train also completes the loading of Brother’s vault, so with no time to spare Courier, Swindler and Sister hop on the bike and board the train, meaning their next stop will be Kanto. After the credits, Bunny and Shark say this was Shinkansen’s purpose all along; to bring people to Kanto. For what purpose we don’t know, as they’re suddenly cut off. But hey, it can’t be good, can it?
Then again, it could yet be good for Swindler, Courier, and the Siblings. For one thing, Hacker is in Kanto now (as far as we know). For another, they no longer have to worry about Doctor stalking them. I’m a little sad she went so completely heel, but she was always the most calculatingly treacherous of the original group, and the undignified, ignominious end she meets was in ironically stark contrast to her lofty goals.
