Chapter 6: Streets Beaten by the Cold Rain — Battle_Preparation.
With the defenses of Academy City is forced to its minimum, Vento manages to slip through and takes out three of the members of the Board of Directors. Meanwhile, the General Superintendent of Academy City initiates a plan to stop Vento, and it requires the Misaka Network's administrator to begin. Right now, that person, also known as Last Order, is now in the hands of Kamijou Touma.

Elsewhere, Accelerator realizes that the girl in white robes — the girl named Index — is in danger and uses the chance to get away with her using a Hound Dog operative inside a minivan as hostage. Accelerator orders the Hound Dog to drive towards a certain hospital.

Kihara Amata is amazed that Accelerator was able to escape his clutches and prepares a high-caliber weapon to take care of him, but he finds himself in the way of Vento, who arrives shortly after Accelerator's speedy escape. Kihara decides to personally take care of Vento, however, upon displaying her unusual ability, Kihara considers that it is futile to fight against her. With the retrieval of Last Order in high priority, he leaves the battlefield, leaving Vento still surprised to face someone with such heartlessness.

Kamijou Touma and Last Order soon reach the remains of Accelerator's last battle and Last Order confirms that the one Touma needs to help was last seen here. Before they can examine further, they are forced to flee when Hound Dog units pursue them. Accelerator also feels pursued as well, but fortunately, they made it to the Frog-Faced Doctor's hospital. After dropping Index at a nearby location, Accelerator continues on.

Meanwhile, Touma and Last Order seek refuge inside a restaurant building to avoid the pursuit of the Hound Dog. To his shock, there are more people unconscious inside, so he planned on seeking another hiding spot. However, he is already discovered.

On the other hand, Accelerator is now walking alone after leaving behind his hostage, and is now trying to contact Last Order (unfortunately, she has turned off hers while opening an electronic lock for Touma to avoid interference). He then decides to contact the Frog-Faced Doctor himself. An exchange between the two manages to clear Accelerator's mind on the task he needs to do, and prepares for the real battle.

Between the Lines
On the gates that divide Academy City and the outside world, Tsuchimikado Motoharu is having a battle of his own. He discovers that the Roman Catholic Church is preparing a direct offensive that is supported by Vento's unusual ability, and in spite of his limitations as a mix of esper and magician, he prepares to fight on.

Chapter 7: Changing Raindrops into the Color of Blood — Revival_of_Destruction.
The ability Vento unleashes in Academy City continues to claim victims. While the face of the intruder reaches Yomikawa Aiho by print, Uiharu Kazari (and a news reporter) fall unconscious after bearing witness to the events unfolding via television. Fortunately, Misaka Mikoto and Shirai Kuroko manage to evade the ability's effects. The Hound Dog units trace Accelerator's location at the Third Resource Recycling Processing Facility. With Scent Sensors utilized to track down Accelerator's traces, they organize a search operation. Meanwhile, their target Accelerator manages to eliminate his scent trail. After a short period of planning, he decides to take care of his pursuers.

Kamijou Touma and Last Order are still up against a wall. He still thinks that the Hound Dog are outside and decides to hide for the meantime. However, he finds out that someone else took them out... and it's an enemy as well. It was the intruder, God's Right Seat's Vento of the Front.

A fight immediately breaks out between the Roman Catholic nun in yellow and Touma, and in spite of having the Imagine Breaker, Vento's attacks are too unpredictable. Fortunately, Touma manages to guess the pattern of Vento's wind attacks, and he decides to hold Vento while Last Order escapes from the dangerous fight. However, Touma's fight becomes difficult with a large amount of civilians in the battlefield, one which Vento exploits well. However, Vento suddenly feels pain and flees before Touma could take the chance to strike back.

Through careful planning and scare tactics, Accelerator manages to take out the entire Hound Dog group by himself. He leaves the facility to look for Last Order again, but not until he takes care of a survivor who decides to badmouth him.

Between the Lines
Tsuchimikado leaves the territory of Academy City and faces a Roman Catholic magician who plans on using stakes inspired by Pythagorean principles to impale Vento's victims. Even though his usage of magic is steadily hurting him, Tsuchimikado continues on and aims for the core of the spell.

Chapter 8: God's Right Seat and the Imaginary Number District — Fuse=KAZAKIRI.
Accelerator's rampage continues. After turning one pack of Hound Dogs into a bloody mess, another group was killed off, but only because they ignored the Heaven Canceller's warnings. Meanwhile, Vento picks herself up after experiencing the adverse effects of being exposed to a certain substance.

Touma decides to look for Last Order again after taking the unconscious people out of the restaurant; he knows that with Hound Dogs and Vento still around, her safety is not assured. He then decides to use Last Order's phone to contact someone. After several tries, only one number responded... It was Accelerator.

In what seemed like a fateful encounter, the two reported each other about what happened on their side, including Last Order's status, and they both find themselves protecting someone. Accelerator and Touma move on their separate paths.

Accelerator manages to locate Touma's last location, but he is contacted by Kihara, telling him that Last Order is in his possession and that she will have a virus installed in her brain to achieve something. Overwhelmed by anger, Accelerator uses his ability to unleash a powerful attack at the Windowless Building, causing the Earth to slow down by about five minutes. Aleister takes no heed of what just happened, and focuses on the next stage of his plan.

Meanwhile, Vento is still struggling from being exposed to an unknown substance and soon encounters Touma again. However, before another battle erupts between them, a spectacle explodes from the distance: an "angel" manifesting on Academy City.

Between the Lines
The battle between Tsuchimikado Motoharu and the unknown Roman Catholic magician is over, but the esper-magician hybrid is shocked to see a simliar spectacle as the manifestation of Misha Kreutzev. He can just brace himself as the clash between God's Right Seat and Academy City becomes inevitable.

Chapter 9: The Differences of Obstacles that Stand in One's Way — Two_Kinds_of_Enemies.
In the midst of the angel's manifestation throughout Academy City, Accelerator hijacks the room of Director Thomas Platinaburg, with the intent of extracting information regarding Hound Dog's missions. He manages to track down the location of Kihara, and he hurries to get there as soon as possible.

Meanwhile, Index, Mikoto and a pursued Touma meet for the first time since the intruder's first steps into the city. Index warns of Touma regarding the angel — whom she thinks is none other than Kazakiri Hyouka — and while Index and Touma head for the center of the manifestation, Mikoto decides to offer her help by taking out the Hound Dogs chasing Touma.

On their way to Hyouka, Index tells Touma about the specifics to the intruder's abilities. However, Index needed help to understand the angel that showed up in Academy City, and with Mikoto's help, she grasps similarities on how it works. With new information on Hyouka's condition, Index heads to look for the "core" while Touma rushes on to confront Hyouka.

Accelerator pushes through Kihara's location and takes the fight to him. However, with only a few minutes until the device that powers his esper ability wears off, he finds himself heavily disadvantaged. Meanwhile, Touma reaches the center of the manifestation and eventually finds himself helpless as he can't touch Hyouka. Then, Vento arrives as well, and Touma's mission to protect Hyouka begins.

Chapter 10: Their Respective Battlefields — The_Way_of_Light_and_Darkness.
Sixty seconds remain for Accelerator to finish off Kihara and save Last Order. The problem is that Kihara still has counters for his abilities, and because of this, the fight seems one-sided. In the end, the device that restores Accelerator's powers dies out. At that time, Accelerator is helpless against the full brunt of Kihara's offense.

Kamijou Touma, on the other hand, is struggling to fend off Vento's attacks while thinking of the civilians scattered around the battlefield; meanwhile, Vento is still trying to stabilize herself while near a "poisonous" source of AIM. Soon, Hyouka — now known as FUZE=Kazakiri — manifests mysterious scales of light throughout Academy City to protect the civilians. With Hyouka trying her best to save everyone, Touma decides to stay strong.

Accelerator's loss of powers soon causes Kihara to lose his cool, since his ability to counter Accelerator is most effective only when Accelerator is a Level 5. Kihara soon wants to destroy Accelerator while not killing him, and it starts with destroying the vaccine that would cure Last Order. However, it seems all is not lost when Index comes to the battlefield.

Vento and Touma continues their exchange, and Touma soon notices that Vento is hurt, but not because of his attacks. Of course, Vento rejects his compassion and tells him of her experiences with science... and her consequent hate for everything scientific. However, Touma points out the flawed mindset she has followed for so long and stamps a fist on her face. It was the end of their battle.

Meanwhile, the battle between Accelerator and Kihara continues, but now, Index is also involved. As Accelerator tries to keep Kihara from touching Index, she holds on to Last Order and thinks of a way to cure the virus that is in Last Order's head in magical terms. Her solution: a song. As she performs an aria for Last Order, Accelerator regains enough strength to fight on, and as Kihara plans on sealing Accelerator's fate... black wings sprout from his back. In an instant, Kihara Amata is thrown into the sky, leaving an orange trail behind him.

Touma's battle has ended, but while he thinks of the outcomes of the battle, another member of God's Right Seat comes to fetch the defeated Vento: Acqua of the Back. Just as quickly as he appears, he vanishes with Vento.

Epilogue: The Paths Which the Winners and the Losers Must Go Through — The_Branch_Road.
With the defeat of Vento and the destruction of the Roman Catholic Church's sieging forces, Acqua reports to a fellow member of God's Right Seat, Terra of the Left, that the mission has failed completely and it is advised for any succeeding attacks to be put on hold for the meantime.

Back in Academy City, Touma watches as FUZE=Kazakiri returns to Hyouka, and he checks if she is fine. Hyouka feels remorseful for what she had done to the city, but Touma is there to lift her spirits.

Accelerator is still crippled without the power from the device on his neck, and he himself is unsure if Last Order has recovered from the virus code. While Index runs off to get a doctor, a group of strangers, including a telepath, approach him. The man who appears to lead them offers Accelerator a choice: to be used as collateral for the extensive damage in Academy City, or to join their organization. Accelerator's positive response was his last words before he is knocked out and taken elsewhere.

The Heaven Canceller has finally returned to his hospital from an emergency evacuation performed the night before, and at the aftermath of the attack against Academy City, he confronts Aleister for playing with his patients. Although the "Frog-Faced Doctor" threatens to stop Aleister's life support systems, he cannot do it, since Aleister is also one of his patients.

After the events that happened on September 30, animosities develop between the Roman Catholic Church and Academy City. It seems that a third world war is about to erupt.
