"What are we going to do now, big brain?" Accelerator sat on his bed, and was thinking this way, communicating with Tree Diagram "Being the unnamed Esper dead, and while Touma is living his love story, we must proceed to the next key, which is Kazakiri" Accelerator did not know her since he never saw her directly, and he asked "Who is she?" and Tree Diagram answered "Every Esper in the city emits the AIM field from his mind, which is a quantum field that influences the collapse of the wave by influence of the mind of the observer, this is related to the theory of the…" Accelerator felt like Tree Diagram was trying to download in his mind all of that scientific stuff "Stop spitting at me all of that crap, get to the point"

Tree Diagram replied immediately, without accusing the insult "Every Esper can influence reality thanks to his power, that emits the AIM field, now Academy City is a giant AIM net, and the manifestation of this net is the Imaginary Number District, which is a virtual place, not existent but still virtually existent, it is actually just virtual, that means it's like a video game, you can get your mind inside it, but not your body, it's just informational. As you know Espers are able to convert Information to Energy and Matter, from Bit to It.

An Esper is able to transform the idea into reality.

The first way to achieve this is Dialectic, do you know what that is?"

Accelerator denied it, and Tree Diagram began to talk about a philosopher called Hegel "He believed that everything that exists is rational and that everything that is rational must exist, and he believed that the transformations of matter and ideas follow the same rule: Dialectic.

There is a Thesis, which is the original idea, the proposition, and it can be compared in the real world to the rational rules, the ideas, the rational mathematic law that rules our world.

Then there is the Antithesis, the opposite of the Thesis, the deny, the doubts, and it can be compared in the real world to the nature, the existing matter, the manifestation of Ideas in the world.

Then there is Synthesis, which is the reconfirmation of the thesis that wins against antithesis, but for some later philosophers it's also a merging with the Antithesis itself, something new yet different.

In the real world it can be compared to thinking creatures like humans, which are part of nature (antithesis) but can comprehend the rationality beyond it (Thesis) and so they can even be manifestations of it.

You see history is not casual, ideas drove it: The idea of French revolution, the idea of freedom, the idea of victory, the idea to migrate in new lands, continents, planets, everything was driven by ideas.

Ideas rule society, the idea of justice, of democracy, but also the idea of victory, of rebellion, of oppression, every idea, when it gets "sustained" by a man, lives in our world.

So our history is filled with ideas becoming realities, but Espers are able to turn their ideas in reality immediately thanks to the AIM field, which is limited however.

But Imaginary Number Distric is not, it's a network of AIM fields, now to turn such a virtuality into reality we must use not a single Esper but a Network of Espers, and we are that network, we will turn a whole virtual reality into reality, and imagine when we will include the whole world: being alimented by a worldwide net of espers, the Imaginary Number District will cover the entire planet, making it as we imagine it, it will be the triumph of the Mind over the World that Fichte had predicted, it will be the final day when humanity will control the whole world with just the power of mind.

No one will die in the virtual reality as no one can die in Misaka Network since his mind is stored here.

No one will suffer in the virtual reality since it will be perfect.

Imagine a perfect world, and the whole world will create it.

By now we need to look for a girl named Kazakiri, which is the manifestation of the Imaginary Number District itself, she IS that district, we need to find her and convince her to join us."

Accelerator had listened to the whole monologue, and as every Tree Diagram's speech it was amazing and full of knowledge, filled with hopes and prophecies.

"Where can we find her? And how are we supposed to merge with her?"

Tree Diagram was silent for three long seconds, which is abnormal for such a powerful computer.

"That's the problem" he explained "We needed the unnamed Esper, because he told me he knew the way to do this".

Accelerator was truly shocked.

He jumped from his bed and screamed in his head "WHAT? Did you know that brat? You knew him? Why didn't you tell me before?"

Tree Diagram was silent, then he spoke with just four words, without telling anything else "That's a long story" and then there was silence in Accelerator's head.

He tried to call him again and again, yet he did not respond.

Accelerator went out of the building to find many of the most prominent Misaka of the Network.

They asked him "What Misaka are going to do to help you?"

Accelerator then said "We have to find A Certain Imaginary Kazakiri and bring her here."

The whole Misakas' army moved on and they reloaded their weapons, but Last Order was holding his arm.

"Tree Diagram told me to tell you something, he said that you will find a nun who knows every possible and powerful magic in the history, we need her too alive"

But then someone grabbed Accelerator by his arm "I can't allow this"

He turned around and he saw Kamijou Touma and Misaka Mikoto, they were together as a couple, but Kamijou had heard the whole discussion "No one can touch Index"

The crowd was still protesting because the government was keeping the ruins and, probably, the rests of the body of the unnamed mass murderer there, while they pretended to destroy every remnant.

One of them jumped on the limit, ran too fast to be touched by the guards and launched a rock against the ruins.

The rock didn't touch the ruins and was sent back fast enough to be almost invisible, and that man hit his head with the same rock he launched.

"You bastard…Is your AIM field still there? We don't believe in ghosts in Academy City!"

He then moved on the ruins and touched with his hand the rock that he tried to hit.

An horrible scream was heard.
