Sometime in the past, Matsuri had learned of Yorito and Aono’s plans to leave the cave where they were staying, and she had assumed that they were going by themselves. Both of them actually wanted her to come with them, and Aono told Matsuri not to say that she’ll be fine by herself because she’s not alone anymore. Back in the present, Aono faces Matsuri and claims that Yorito chose her. Matsuri knows that Yorito wanted to make Aono happy and thinks that Aono should be glad that Yorito puts her first. Yorito has always wanted not to cause his sister sadness and pain, and Matsuri couldn’t stand it. Matsuri then admits that she likes Yorito and that she doesn’t want to be separated from him. She asks Aono to give Yorito to her, though she feels that she’s already gotten him and reveals that he’s at her place now. As she starts to leap away, Matsuri suggests that they should decide who can be with Yorito.
Matsuri returns to Yorito, who is waiting for her in an abandoned movie theater, and the two pretend to watch a horror film. When Matsuri thinks that Yorito doesn’t like them because he’s scared, Yorito claims that he’s not and wants to prove it next time, but he then realizes that there might not be a next time. Matsuri, however, still says that they should go see one some day. As for Aono, Matsuri feels that this is all her and Aono’s problem and that Yorito was the one who got dragged in. In talking further about horror films, Yorito wonders aloud what dying feels like, and although Matsuri has lived for a long time, that is the one thing she doesn’t know. Aono has meanwhile arrived at the abandoned district and calls Matsuri out. She feels that it’s pointless to fight because if she gets defeated and loses her powers, Yorito won’t live anymore. Matsuri knew this already and is okay with it because her goal is to erase poor Yorito.
Since the two girls are serious, they start fighting sword against paper. The both use the full extent of their abilities, with Aono manipulating everything she can get her paper onto to hurt Matsuri while Matsuri wields the sword and her own decay powers. At one point, Aono seems to gain an upper hand after having barraged Matsuri with paper missiles and demands Yorito back. Matsuri replies that it’s impossible because the real Yorito is gone – dead since that time. Aono feels that by this logic, she’s also been dead since that time, and she blames Matsuri for all this. Right before she charges forward, Matsuri replies that this is the reason she’s returning everything to how it originally was. The two clash again and after kicking Matsuri down, Aono uses her paper to weaken a section of wall to crumble down onto her opponent. Matsuri manages to respond quickly enough to decay a pipe structure to form a cage to protect herself.
As she rushes to attack again, Matsuri remembers how she had revived Aono after Aono committed suicide. At the time, Matsuri had been lonely after having understood what it means not to be alone and what the warmth of being with someone is. Matsuri now swings at Aono and manages to slash her arm, but to Matsuri’s surprise, it turns to paper. The real Aono has already found Yorito in the movie theater, meaning that the one Matsuri is fighting is a fake. This fake explodes in a whirlwind of paper that tags everything around Matsuri, including the oil drums that soon come flying at her. One of them knocks her down right beside a construction crane that now aims its arm at her. Inside the theater, Yorito tell Aono that he can’t be together with her and that he’s the one who asked Matsuri to erase him. The reason is because he’s not Yorito or anyone, so he wants to return to his true form, together with his sister.
Aono refuses to do this because if both she and he disappear, then nothing will remain. If this is what is supposed to be right, then she wouldn’t have created him in the first place. She had done it because she thought she could with the power of the Yaka and because she thought she could live with Yorito. In anger, she question if it’s meaningless and then pins him against the wall with her paper. Matsuri has meanwhile been beat around by the objects under Aono’s control, but she manages to make her way back to the movie theater. Aono hears her coming and starts to head out to meet her, but Yorito first says that even if there is no Matsuri, he still refuses to go with Aono. When Aono replies that she’ll forcibly take him, Yorito asks if it’s because he’s something created by her. Aono denies it, but Yorito suggests that if he were the real Yorito, she wouldn’t have said something like that. He feels that things don’t always happen like you want them to, but that is what living is. Aono, however, continues to insist that he’s Yorito – her little brother – and heads out to face Matsuri.
Matsuri and Aono both want to end this now, and although Aono throws a knife, Matsuri presses forward with her attack. Aono manages to use her paper to get Matsuri to drop the sword, but Matsuri responds by getting up close and throwing Aono through the theater wall. Before the dust can clear, Matsuri retrieves the sword and stabs Aono in the gut. Unfortunately, the Aono she stabbed is another fake made out of paper, and the real Aono slams Matsuri against the movie screen with a wave of paper. Aono then forms another knife and heads toward Matsuri to finish this, leaving Yorito no choice but to break off his arm to free himself. When Aono charges Matsuri, Yorito tackles his sister to the ground before she can reach her. Picking Takeshi’s sword back up, Matsuri starts walking towards them, but the movie screen behind them suddenly lights up with a scene of a blue sky.
Matsuri pauses for a moment against this background before she decides to stab herself in the stomach. Earlier, Takeshi had told her that putting her life onto the sword would allow it to return another Yaka to being human. Indeed, the sword seems to absorb Matsuri’s blood and continues glowing even after Matsuri pulls it out of herself. She then raises it to stab down on a now-frightened Aono.
Well there were some great fight scenes this episode, more than enough to rival even some of the action heavy shows. I liked how they mixed the past scenes with present fight, and I also thought the film of the blue sky as the background for the final scene is a really really nice touch. Actually, that blue sky background seemed to have extra significance given how long Matsuri paused in front of it before finally stabbing herself. She spent most of the episode trying to just stab or slash Aono, and it wasn’t until that blue sky appeared that she seemed to opt to return Aono to being human by stabbing herself first.
This all leaves me with a lot of questions about how this series will end. It seems like there’s a pretty good chance that Matsuri will die, and if she succeeds in stabbing Aono, then Aono will revert back to being a human and lose her Yaka powers. If Yorito also theoretically disappears when that happens, then it would leave Aono all alone. That doesn’t seem like it’d be a very satisfying ending to me, though keeping made-out-of-paper Yorito alive doesn’t seem very like a great choice either. I guess we’ll have to wait until the finale next week to see what happens.
