Accelerator, ranked number one in Academy City and the strongest Level 5 esper.

He came to a place where he shouldn't have been.

"Bedroom? Whose bedroom?"

Accelerator recognized it immediately; it should be a girl's bedroom, but whose? He didn't know.

The last moment of his memory should be when he killed that bastard called Phantom, Accelerator tried to recall what happened after that, but—

A sense of foreboding spread through his memory.

"...It's that one again?"

Black wings—something even Accelerator himself couldn't understand or recognize.

Whether it's a superpower or not is unclear. Whenever those black wings appear, it inevitably triggers unimaginable killing intent and rage in Accelerator. Those black wings seem to be something beyond the human realm, but even the first person in Academy City doesn't understand what they really are.

He scratched his head, feeling a headache coming on.

Ultimately, I should be in that apocalyptic zombie world.

Why would he suddenly appear in a place like this? Even when he looked out the window, the world outside was bright and clear. This place couldn't even be considered a post-apocalyptic survival situation.

Could it be that we've returned to Academy City?

As Accelerator thought this, he also touched the electrodes on his neck to check the charge level.

then.

He pressed the switch, but there was no response.

"what?"

The first person seemed startled; he pressed the switch several more times, but there was no response.

The electrodes have no power, and electronic products without power cannot be turned on no matter how many times they are pressed.

but.

"Hey—wait a minute."

The first person immediately removed the electrode-like devices attached to both sides of his brain without hesitation, and even took off the black electrodes on his neck.

Nothing happened.

Even after the electrodes on his neck were removed, he was still able to think and speak normally, and even do whatever he wanted freely.

Before this, the first person in Academy City who didn't rely on electrodes should have been unable to even walk or think.

Why? What exactly caused it to become like this?

The first person suddenly stopped.

If the head wound heals, then wouldn't that mean—

He slightly raised his hand, and then...

—The air in the room gathered at his fingertips, forming a tangible wind spear.

"My abilities... have been restored."

It is no longer a power that can be achieved by relying on simple electrodes, nor by relying on the computing power of the Misaka Network when it is idle.

That was Accelerator's own genuine, unadulterated computational power.

His wound in his frontal lobe has completely healed, and he has no problems with either his superpowers or his thinking abilities. Now, he can freely use the strongest superpower in Academy City.

But why? How exactly was all this accomplished?

"The mission reward has been sent."

Suddenly, a mechanical voice rang in Accelerator's ears.

"who is it?!"

His eyes widened, and he ruthlessly pulled out the pistol from his pocket, looking around in an attempt to find the source of the voice.

But there was nothing around; not even a single insect, let alone a person.

But the sound rang out again.

"The host has completed the first official mission. The second official mission will officially begin in seventy-two hours. Please make the corresponding preparations in advance."

"System notification: The host has already established a connection with another user in the current world. Since the host has previously formed a queue with this person, the system will default to the host's inner choice for pairing, successfully connecting the host with this user."

"System prompt: The host can open all interfaces of the system and use all functions within the system simply by relying on his mind."

"The system content is structured as above. We hope you have a pleasant time using it."

Accelerator stood there, stunned.

With his subconscious thought, something like a pop-up window instantly appeared in front of him and then expanded outwards.

He saw something like an instruction manual that only appears when you use the system for the first time.

—Soul System.

This system was created to perfectly unleash and expand the user's power limits. The system itself can completely unleash all the potential deep within the user's soul and transform it into tangible power, which is then given to the host.

Users of this system are urged not to include content from novels similar to the "Infinite Flow God Space" genre into this system.

The Soul System does not have any point exchange function, does not have any function that will kill the system user if there are not enough points, does not have any function to evaluate power level, does not have any function to increase the power of the system user through a level system, and does not have any main god.

The purpose of the Soul System is to allow users to develop their own inner, most suitable, true abilities.

The system's function is solely to lead users to worlds that are infinitely vast, infinitely expansive, and infinitely possible and impossible. In each world, it issues users free-type tasks, and upon completion of the task, the Soul System will develop or create equipment or power best suited to the user's own power level and specifications as a reward.

If a system user fails multiple times in missions across different worlds, the Soul System will issue a warning and will ultimately take measures to forcibly seal all of the system user's power back to its initial state, and randomly select a suitable world to re-enhance their power.

If a system user dies, the Soul System can forcibly revive the system user through certain special means.

After undergoing an unspecified number of world travel missions, the Soul System will unlock at least one world mission of the two-way challenge type. There are only two teams, A and B, with a minimum of one person per team and no maximum limit on the number of people per team. At the same time, the Soul System itself will automatically judge the fairness of the battle based on the organization. If it is not objective enough, the system will make some modifications.

After completing the challenge, the Soul System will grant additional special rewards to the winning system user, depending on the circumstances.

If a system user possesses equipment or abilities that require cross-world or special circumstances to function properly, the Soul System will do its best to convert the usage specifications of that equipment or ability for the system user, so that the system user can successfully use that equipment or ability.

The Soul System can connect two or more system users together, creating a situation similar to the Friend System. Once two system users are successfully connected, they can participate in the same type of world missions together. In addition, challenging world missions will also bind the two users to the same team by default.

Each world mission is judged by the system based on the user's strength and other factors, and the system will select the most suitable world for the user to go to. In each world system, the user must complete the mission of the current world before he/she can go to a new world or return to other worlds. After each world mission is completed, the soul system will lead the user to a default low-combat-power world for appropriate rest.

The above are the main functions of most soul systems. System users can explore other functions of the soul system on their own in the future.

The system content is structured as described above. We hope you have a pleasant experience using it.

pat.

Accelerator even dropped his pistol to the ground as a result.

"What's this?"

The first one gently stroked his head, and a few beads of sweat seemed to be dripping from his forehead.

It was simply because of astonishment.

He could hardly believe that what had just happened was real, but there it was, the huge screen right in front of him.

It told Accelerator that this was reality.

The first person took a deep breath, picked up the gun that had fallen to the ground, and turned the screen in front of him back on.

The screen only shows a small portion of the image.

At the top is 'Check Status'.

Below that is 'Start World Quests'.

Below that is the 'Item Inventory'.

And finally, what appears is a gray-black border without any text.

This is reality.

Such an absurd thing happened to the first one, just like in novels where users chosen by certain gods are added to various movie works to participate in a great melee.

But in fact.

This so-called soul system is fundamentally different from the system of the main god space that the public is familiar with.

So, is that the reason for everything?

"Why did I end up in that zombie world? Why did I meet those guys? Why did I leave Academy City...? Is it all just because of this thing?"

If that's the case, Accelerator really doesn't want to have this so-called soul system.

If he's leaving Academy City and that brat just to gain power, then he really doesn't need that so-called power.

Especially now, when we still don't know what's going on with that kid...

"How can I go back to my original world?"

"System prompt: If the host wishes to return to your original world, you can try to complete world missions multiple times. There is a good chance that you will be able to return to your original world."

"So you're saying there's no way to go back now, and it's all down to chance?!"

What a joke.

The first one clenched his fists tightly, and a hint of anger appeared on his face.

"You bastard... If you were a human being, I'd kill you right now."

Soul System.

The exact source is unknown, but it is known that this thing transported Accelerator to that apocalyptic world, and it is also believed that it brought Accelerator to his current location.

and.

He turned on his phone, and his contacts were the same as in the post-apocalyptic zombie world; he couldn't reach anyone.

You bastard...!

The more the first person thought about it, the angrier they became.

Although his abilities have been restored, he probably won't be able to return to the world where Academy City is located during this period.

The only way is to keep trying by activating those so-called world missions, one after another, in order to have a chance of being selected from the original Academy City world.

Once you've been to a world, you can travel back and forth freely; that guarantee is enough.

However, there is something even more important.

"Whose house is this anyway?"

Just as Accelerator was thinking this way...

The door in front of them was opened gently.

Almost instinctively, Accelerator raised his pistol and aimed it at the figure that was about to walk in front of him.

Regardless of whether the other party is good or bad, first, intimidate them and strike first.

As he was thinking that.

What comes into view is a head of long, azure-blue hair with a hint of emerald green in pigtails.

"—Huh?"

It was a girl, a girl with long, light blue hair in twin ponytails, dressed in casual home clothes.

The girl possessed an idol-like aura and an impeccably cute face, exuding an almost perfectly fitting aura.

And then, that's how it is.

The strongest in Academy City stood in this room, holding a pistol, looking at the twin-tailed girl in front of him with a somewhat astonished expression.

A gentle breeze blew in from the window, causing their hair to sway softly.

It was as if all of this was bound together by fate, reconnected once again.

Chapter Twenty-Five: The Daily Life Unfolding in a Tranquil World

Hatsune Miku immediately froze on the spot.

What, what's going on? Why did he suddenly point a gun at me... What kind of bizarre turn of events is this?!

"Why are you here?"

"What are you saying about me being here... This is someone's home! Where else could I be if not here!"
