With time running out, Accelerator isn’t able to find Last Order at the restaurant where he left her. The waitress informs him that a guy in a white coat took her, so he calls Yoshikawa to figure out what to do. She informs him that Amai should still be in the city, so Accelerator goes to track him down. He finds Amai in his car with Last Order in a deserted area, and when Amai tries to run him over, Accelerator easily stops the car. He knocks Amai out as Amai tries to exit the car, and after examining Last Order, he tells Yoshikawa over the phone about the equipment hooked up to her that’s displaying her ever increasing brain cell rate of operation. Yoshikawa is headed towards them right now, however before she can get there, Last Order starts spouting nonsense, indicating that the virus is activating earlier than expected. She informs Accelerator that there are 10 minutes before the virus is transmitted onto the Misaka network, and she feels that there’s only one thing he can do now: kill Last Order.
Accelerator, however, realizes that Yoshikawa had earlier given him Last Order’s personality data from before the infection, and if he can control her brain’s electric signals, then he can tamper with that data. He thus decides to compare the data from before the infection with the data in her head and then get rid of all the extra. As he’s doing so, he realizes that he’s also getting rid of all of Last Order’s memories from the past week, but he thinks that it’s better if she doesn’t remember. Unfortunately, Amai regains consciousness at around this time and points his gun at Accelerator. With what he’s in the middle of doing, Accelerator doesn’t have any spare computing ability to reflect a bullet, and right as he’s finishing the job, the bullet hits him in the head. Accelerator did finish though, and when Amai realizes that the virus is gone, he tries to shoot Last Order as well. Luckily for her, Accelerator isn’t dead yet, and he now protects Last Order
Amai questions what someone like Accelerator is doing, so Accelerator acknowledges that it’s ridiculous that trash like him could be thinking about saving someone. However, he feels that Last Order has nothing to do with them, and he won’t let the remaining Sisters die. The problem for Accelerator is that he loses consciousness before he can do anything to Amai, so Amai has the upper hand once again. Before Amai can finish off Accelerator though, he’s shot in the back by Yoshikawa who had finally arrived. She secures Last Order, and when Amai struggles to get back up, she apologizes and comments on how naïve she is. Yoshikawa isn’t concerned about Accelerator because she knows an unusual doctor who has a frog-like face and is called Heaven Canceler. When Amai questions what she’s doing, she explains how she didn’t want to be a researcher and had instead wanted to be a kind and gentle teacher. She wanted to do something kind for once, so she offers to not let him die alone by killing her with him.
The two shoot each other at the same time, and when Yoshikawa regains consciousness, she finds herself alive in the hospital. The frog-faced doctor had taken care of her, but he reveals that it was Accelerator who had used his ability to control the flow of blood and prevent her ruptured coronary artery from killing her. Accelerator, however, had suffered some damage to the frontal lobe of his brain, and it’ll affect his speech and calculation abilities. This last part would mean that Accelerator has lost his powers, but the doctor vows to get him back those abilities by linking him to the 10,000 remaining Sisters on the Misaka network. He also reveals that the higher-ups found out about this incident, so the research lab was broken up and Yoshikawa has been laid off. She realizes that this means she can’t be a researcher anymore, but the doctor thinks that there are a lot of other paths. When Yoshikawa asks the doctor to save Accelerator, he promises to return from his battlefield with the patient who has up until now always fought by himself.
It seems like it’s a bit late in the series to be introducing a new ED, but I can’t really complain since it’s something new to look at and because I rather like this song. Like the first ED, this is a fairly slow song, so I see it as helping the audience unwind after episodes.
Now that this is over, I’m left wondering why I should care about any of these characters other than maybe Accelerator and the doctor. Amai was a crappy villain who’s now dead, Yoshikawa is a boring character who’s no longer a researcher – I could have done without her long speech about how she wanted to become a teacher – and nothing that happened between Last Order and Accelerator is relevant since she doesn’t have those memories anymore. I had hoped for more from Last Order, but she was more or less just a prop this episode, and there are no hints that she’s ever going to show back up in the story. So much for being Accelerator’s sidekick.
As for Accelerator, he grew a little as a character I guess, but it seemed forced at times. I will say though that it was a nice touch of irony that he ended up being linked to the Misaka network. In any case, I think the only character I came out of this mini-arc really wanting to know more about is the frog-faced doctor. He all of the sudden seems like a much deeper character and might have some hand in whatever the overall plot ends up being about. Speaking of which, it should be about time for them to get started with the final arc of this series, and the preview shows what appear to be several new characters.
