BNHA: Accelerator The Strongest Hero

Just as Kiyama Harumi activated her abilities, manifesting the power of the [Unknown Field], everyone in the 10th District who had previously used [Fantasy Hand] fell unconscious. They lay on the ground peacefully, like tired children sleeping after play. Even Chisaki Kai, the backer of the [Shie Hassaikai], was no exception. 

This sudden situation caught the frontline heroes and police officers confronting them completely off guard. After all, one second they were on the brink of life and death, and the next, they were sleeping defenselessly like babies. Such a strange scene would make any reasonably intelligent person feel alarmed.

Yet, Kiyama Harumi had completely changed from her previous weakness, as if her spirit had fully returned to her body. She faced Accelerator firmly and earnestly tried to persuade him.

"Accelerator, there are only seven Level 5 esper users in Academy City." 

"On August 21, during the 10032nd experiment with the train formation in the 17th District, he was defeated by a random powerless person (Kiyama Harumi was unaware of Touma Kamijou's information), and the Absolute Ability Plan was frozen." 

"On August 31, he made contact with the final work of the 'Sisters' command tower, and then was injured by the former researcher of the 'experiment,', before going missing." 

"I hope I didn't get that wrong. I really didn't expect to see you here, and you actually turned out like this."

Hearing her words, even Accelerator had to raise his alertness to the highest level. He had never been this cautious, even when facing the dark emperor of the other world.

From her earlier remarks, it seemed very likely that this woman came from the same Academy City as him.

"—Tch! You really know a lot, don't you?"

"So what?"

At that moment, Accelerator noticed several strange changes in Kiyama Harumi. The left part of her eye transformed into an indescribable spiral, and a faint halo reminiscent of the famous "light" from myth formed above her head.

Kiyama Harumi smiled calmly. 

"There's no need to be so wary. I'm not from your world, and I don't even want to continue fighting with you."

"All this bizarre information comes from my Quirk."

"Whispered."

Accelerator completely ignored the meaning behind her words.

The [Whispered] Quirk allows the user to hear [information]. About a year ago, Kiyama Harumi, who was originally a research scientist for battle gear for professional heroes, suddenly heard unique information from a special domain.

It was as if she had experienced events from several different worlds herself. Most strangely, the Kiyama Harumi in that other world also had a group of students whose names and Quirk effects were nearly identical to those from Academy City.

At first, she didn't pay much attention to it until one day, her beloved students suddenly fell into a state of Quirk rampage and unconsciousness, as if bound by some invisible hand.

However, in that other world, there were no characters like Therestina Kihara Lifrain or her accomplice Kihara Gensei.

Initially, to awaken the children, Kiyama Harumi worked hard with the professional heroes she had known in the past.

But those efforts had no effect.

Many of the professional heroes guarding everyone didn't have endless time to spend on a group of children with no hope of waking up. After all, there were too many people in this world that needed protection.

Just when she was on the verge of despair, Kiyama Harumi suddenly recalled what she had done in another world.

By coincidence, she discovered the commonality between these worlds—AIM diffusion fields.

Thus, with a year of support from [Fantasy Hand], it became one of the weapons Chisaki Kai used to achieve his ambitions.

Meanwhile, Accelerator suddenly realized the source of the abnormal feelings that had troubled him since arriving in the other world.

—AIM diffusion field.

This is a field unintentionally emitted by ability users, created by the influence of [personal reality] reflecting in three dimensions. 

Although this special field is called a field, it doesn't possess the characteristics of a normal field and can't be classified as "vector," which is the true reason for Accelerator's feeling of abnormality. Moreover, the AIM diffusion field, as the fundamental theory of superpowers, has many aspects related to the [unknown realm].

In Academy City, the so-called AIM diffusion field can be observed by applying a dual-flower cyan dye to a glass screen to see the light rings surrounding the human body, displaying a multitude of colors like a laser, similar to the glow of a person.

The people from the other world also possess a fundamentally similar force field, but due to the Quirks evolving over generations, or because Quirks are so prevalent, the new generation of [Quirkless] individuals has become rare.

As a result, the observability of the AIM diffusion field has decreased, to the point where even Accelerator didn't notice it.

The reason someone was able to observe this fact through Kiyama Harumi is that the unique glow of the AIM diffusion field around her is like the sun descending to the earth.

In the other world, [Fantasy Hand] acts through the AIM diffusion fields of hundreds of thousands of people (both Quirkless and those with weak Quirks) as a medium, using the soul material of all its users as a driving force, creating a domain that greatly enhances the effects of Quirks through "resonance," "patterns," and "fusion."

Whether it's a Quirk or a superpower, their essence is that they are foreign elements that influence the objective world.

The [Fantasy Hand] temporarily opens the wall that separates them from the objective world through resonance.

Kiyama Harumi, the current wielder who has gathered the strength of hundreds of thousands of ordinary people from the other world, can face the strongest battle-type hero of the new generation, [Vector Manipulation], with such calmness.

In terms of energy level, while the number may be lacking, the combined quality of that energy is powerful enough to change the world.

So, Kiyama Harumi said, with her hands tucked into her white coat:

"It seems you've made up your mind, and you're not planning to let me or him go."

"Then you must stop me, who holds the power of hundreds of thousands, right here."

"Even you, I bet you've never faced a foe like me."

In the end, he responded, smiling calmly.

"You talk too much. Bring it on."
