Kusunoki is barely two minutes into breifing the Lycoris for the Enkuboku operation when Takina interrupts her after spotting Chisato’s name on one of the rosters. She realizes something’s up and leaves the bus to go find her. Chisato and Mika are being led by Robota exactly where Majima wants them to go.
Mizuki and Kurumi are at the airport lounge, and part ways “forever” without much fanfare, only for Kurumi to deplane from her luxurious first-class seat (Mizuki got stuck in economy) when her turbo-hacking reveals there’s a second artificial heart out there.
Takina arrives at LycoReco to find it abandoned and Chisato and Mika’s phones left behind. Then she gets a call from Kurumi about the second heart: it’s an improvement on the one Chisato has, which suggests she could live a full life with it.
The person in possession of this second heart? Yoshimatsu Shinji, naturally, who Kurumi shows Takina has been taken captive by Majima at the old tower where he and Chisato first crossed paths. Takina, who had been in the middle of the operation with Fuki & Co., excuses herself, even if it means she’s done with the DA. Fuki even lets her go, knowing that’s the best move. But before she leaves, Erika gets to have a nice moment, hugging Takina and thanking her for saving her.
Takina’s reason for abandoning her DA duty is simple: she can’t save Chisato from the Enkuboku. She’s in the wrong tower. So she runs with everything she’s got to the other one. Majima, meanwhile, is able to get back on the airwaves thanks to Robota, who uses Radiata’s heavy defenses against itself with thousands of simultaneous hacking attacks.
This enables Majima to officially expose the Lycoris by showing video footage of them walking around the tower with guns near pools of blood. When he tells those who found the guns he left for them to find to watch out for Lycrois, there’s a confrontation that results in both Lycoris and civilian getting shot. Kusunoki’s failure is quickly becoming a bloody fiasco.
Chisato arrives at the old tower, goes inside, rides the elevator up as high as it will go, then heads outside for a bit of acrobatics. She not only has to maintain her own balance to keep from falling to her death, she also has to make sure the thugs she shoots don’t fall to theirs.
Because Chisato doesn’t kill anyone she encounters, it makes sense that she’d act and talk so casually, even playfully while dispatching them non-lethally. She’s not just making her way to Mr. Yoshi, she’s having fun while doing it. Then the fun suddenly stops when Majima drops the shutters and leaves Chisato without her most powerful attribute: her sight.
The two empty multiple clips at each other, but Chisato’s dodging ability isn’t too hampered, while Majima’s supernatural hearing enables him to dodge her wild shots and sneak up on her from behind multiple times. As the two twist and tussle in the dark, it’s clear the fun is back: two realtively evenly-matched opponents are going at it.
Then , just when it looks like Majima is about to get the upper hand, Takina literally smashes through the metal shutters and comes between him and Chisato, packing live ammo. Right now, the DA being exposed and the potential destruction of the new tower doesn’t matter. Takina’s there to save Chisato and Yoshimatsu make it out of there alive, which means Majima is simply in the way.
