Akira may as well be back at the office, as he’s completely under the boot-heel of Chief Kosugi—a constantly apologetic, servile cog in the machine. Watching him, and having to pour beer and endure sexual harassment from Kosugi, dredges up a lot of memories for Shizuka. She doesn’t like those memories, and she doesn’t like watching Akira like this.
Shizuka’s father was essentially Chief Kosugi, only richer and more powerful. So obsessed was he with molding Shizuka into his scion that he told her to get rid of a sickly puppy she found on the street, because she needed to cast aside the weak. When she didn’t, he had the dog put down. Throughout her life, his constant mantra was You only need to obey.
Those are the same words used by Kosugi when on the last day of his servitude they agreed upon, the Chief suddenly switches gears from yelling to acting benevolent, telling the thoroughly downtrodden Akira that he can just stay here and work for him indefinitely.
Up until witnessing Akira in this state, Shizuka had more or less obeyed her father, which resulted in her having a prosperous job but very little in the way of joy. It’s only now that she realizes she wasn’t benefitting herself obeying her father and letting him dominate her.
When she finds Akira’s bucket list in the RV, she reads it over and smiles at how weird some of the items are. Then, in a moment of inspiration, adds a new item to the list.
The morning they’re to depart, the brainwashed Akira shocks Shizuka and Kencho by saying he’ll stay, parroting the reasons Kosugi mentioned: freedom is tough, the world outside is dangerous, and he’s not good for much, so he needs to stick with the boss.
Shizuka is fine to leave without him, but when he uses the word “need” over and over again, she can’t help but remember her father constantly drilling that into her head. She never snapped back at her father for fear of being thrown out on the street, but she’s officially had it with that word.
Shizuka’s parting words, about Kosugi being nothing but a sad, pathetic parasite who makes himself bigger by putting others down and wants to steal Akira’s free will, his very soul. She stands in front of the image of her younger self and says she’s getting away from this gross shithead with all due haste, because she’s not giving herself over to anyone ever again.
She then shows Akira his bucket list, tells him he’s not a machine or a zombie, and that he should be allowed to do what he wants, not be browbeaten into doing what others think he needs. When he sees the item she wrote—Tell off my jerk of a boss—and Kosugi snatches the book and prepares to stomp on it, Akira protects it with his own body.
His eyes now returned to normal thanks to Shizuka, he fulfills that bucket list item by telling Kosugi off. Whatever the Chief believes he still “owes” him, Akira tells him straight up he won’t be able to make it up to him. Sorry! As for the threat of being eaten by zombies, it’s better than being worked like one.
As Akira is about to leave with Shizuka and Kencho, a delivery van arrives and a zombie bursts out, causing pure chaos and sending Kosugi, who is not built for running, running for his life.
Because Akira’s a good guy with delusions of superheroism, he rescues his boss by coordinating with the baseball players to pen in all of the zombies, then blow them up by igniting propane tanks.
Shizuka can’t help but smile and laugh at the fact Akira keeps pulling off the craziest shit that ends up working. When he thanks her and she tells him it wasn’t meant to be a compliment, they both laugh.
Shizuka didn’t just wake Akira up, but thanks to her words and his actions, now all of them have had their fill of Kosugi as their leader, and abandon him en masse. He believed he was on the road to running Japan, but it only took two days for the sad little king’s hill to melt down into nothing.
Back on the road (and hopefully watching very carefully for more spike strips!), Akira reveals that he literally blanked out whenever he was around Kosugi, so while he remembered the torturous work, he remembered little of his interactions with him. That’s probably for the best.
Akira does go on to worry if he’s cut out for anything job-wise, but that’s where Shizuka comes in to say something Akira would have said to her a few days ago: So what? The time for needing to obey others who don’t have your best interests at heart is over. It’s time to do what they want. It’s the freakin’ end of the world…if not now, when?
