Mairu and Kururi sorta narrate this episode, but only sparingly, but they have a couple funny moments despite never appearing in the episode (even through chat): First, Mairu interrupts just before a masked man tells Shijimi his name. Second, Mairu wonders if some kind of world revolution is afoot, and Kururi calls that “a stretch.”
That’s certainly true, since Durarara!! has virtually strayed outside Ikebukuro’s borders, nor has there ever been any indication that the things that go on there have any effect on the outside world. But what if Ikebukuro was the world, in it’s entirety, as for all intents of purposes, it is in the show? It would mean the world really was in the midst of upheaval.
All the characters who dot Ikebukuro’s landscape are the players who shape Ikebukuro World. Rather than gangs, the Dollars and Yellow Scarves and mafia are nations; their leaders world leaders. And Saika isn’t just a parasitic demon, but an ideological movement. Anri, Niekawa Haruna, and Kujiragi Kasane are three different “schools” of Saika, and those schools butt up against each other this week.
Ever since Anri cut Haruna, there have been two Saikas inside her mingling, and since Anri’s Saika is older, it’s a form of control that’s also opened Haruna up to other emotions and ways of thinking – as well as Anri’s confused feelings for Mikado and Masaomi. Haruna wants to join forces – Anri will help her attain “real love” with Takashi; and in return she’ll help Anri with her romances.
Anri declines, because she doesn’t want to use Saika for nefarious purposes, only to protect; which provokes Haruna into fighting her. That’s when Kasane, who was hanging out in the park the whole time, neutralizes and chastises the “daughter” Haruna for raising a hand to her “mother” Anri (speaking in Saika terms, of course.)
Of course, this doesn’t mean Kasane is on Anri’s side. In fact, Kasane is somewhat surprised by how little Anri has mastered or even used Saika; which frustrates her more now that she knows how good having freedom feels. So she breaks out a proposition, just as Haruna did. No joining forces; rather, she’ll take Saika off Anri’s hands for a handsome, fair sum. I mean, if she’s using it so little, she doesn’t really need her, right?
The only problem is, while Anri certainly hasn’t mastered Saika, she has more or less accepted her as a part of her, not to mention relied on her in times of trouble; she’d likely be dead without her. Losing her wouldn’t necessarily make her human (a human would never have had Saika to begin with), so I’m doubtful she’ll make the deal. However, I’m also doubtful Kasane will give up easily.
Despite the rarity with which she needs or uses it, Anri has become dependent on Saika as a form of defense in a dangerous Ikebukuro World; a weapon to keep sharks off her in that world’s roiling waves. Meanwhile, Mikado tells Izaya in a lengthy but wonderful phone call that he wishes to remain in a boat, detached from those waves, but able to watch them ebb and flow and be entertained.
That’s the “interesting world” he first sought when he arrived in Ikebukuro World (an arrival akin to a birth). It’s why he founded the Dollars. And it’s why he’s evolved into someone who isn’t the slightest bit surprised by the face Celty’s head is in a bush (though he is relieved by Mika’s hilarious voicemail message about it not being her head).
Now he’s put himself in a position to press the reset button on the Dollars, hoping he’ll catch lightning in a bottle once more. He and Izaya are revealed to be a lot more alike than I ever considered, as the two may use different metaphors, but both seem willing to act as both arsonist and firefighter in order to mold the world into something interesting.
I’d say Mikado differs in that he has empathy for humans and has a few he actually cares about and doesn’t want swept up in those waves…but I doubt Izaya wants his sisters hurt, either. It’s also interesting in this particular situation, that Mikado knows something – that Celty’s head was found in the park – before Izaya.
That’s a rare moment of someone having the upper hand over Izaya, which is always nice. And knowledge is definitely power in Ikebukuro World; just look at which Saika dominated the other two, and why. That being said, there’s nothing Izaya adores more than humans acting unpredictably.
The Saika trio and Mikado-Izaya phone call are the A/B plots, but the episode still managed to fit in a C and a D: There’s the hiding Shijimi, who is approached by a masked man who was in the passenger seat of the car that hit Dotachin, offering to bring him in on some kind of heist of Yadogiri Jinnai’s fortune.
Then there’s Chikage confronting Masaomi and his Yellow Scarves, 1 on 8, and giving them a choice: let themselves be taken over, or be destroyed. And we know there’s no one among those 8 scarves who is a match for Chikage alone. Mairu is right: the time of revolution, war, and global upheaval is nigh in the Ikebukuro World.
