Accelerator.

All the physical laws, Honkai energy, time, space, and spiritual power that exist—

The "one who controls everything" truly is someone who can control the direction of all energy in the world.

The guidance he received from the god who appeared during the Second Collapse fourteen years ago was absolutely correct.

The path we need to take is already right in front of us.

"Well then, let's wait and see."

Even if K423, this copy of Kiana, loses the power originally belonging to the Herrscher, it doesn't matter.

For Otto, a brand new plan was laid out before him.

"I believe success will come to me soon... I also believe that we will be able to meet again soon."

"Wait for me, Karen."

This man's obsession will never end.

Even though what he was facing was a monster that he couldn't even control.

——————————————————————————————————————————

"Thank you for your hard work, all three of you."

After everything was over, the three of them walked out of the room, where Theresa was waiting for them at the door.

Tesla, Einstein, and Accelerator.

Relying on Accelerator's control over the three gems, the three of them developed a container capable of controlling the gems' energy.

Now, the Far East Branch and its members can only remain on the Hyperion.

If they were to return to St. Freya Academy like this, it would inevitably drag the Valkyries there down with them. Although the Schicksal headquarters is temporarily unable to operate due to Accelerator, it would be better for Theresa and the others to be more careful in their next actions.

The group is currently located on a nearby island in the distance.

"so."

After stepping out of the Hyperion's laboratory, Accelerator stood directly in front of the group.

What are your plans after this?

The Far East Branch has become a complete enemy of the Destiny Headquarters.

After that, Theresa and her group would never be able to return to their original lives.

even so.

"Hmph, it doesn't matter if we don't go back to that kind of place."

These are words from Himeko Murata.

"Not only did they wantonly use my students as human experimentation material, but they also planned to revive the consciousness of the Herrscher. No matter what, I will no longer help those evil guys from Schicksal."

"...That's true."

Fu Hua, standing beside her, said the same thing.

"No matter what Otto's plans are, I will never forgive him for using living people as tools, and I will never work for him again."

"...I'm going to find Grandpa."

After much deliberation, this was Theresa's answer.

"I must get an answer from him: why... why did he do this to Kiana, and what exactly is his intention? What was the purpose of all this?"

"I will definitely get the answer from him personally."

It seems that no matter who it is, in the end they all chose to go against fate.

The Far East Branch, having joined forces with the conservatives of Anti-Entropy, will then confront the entire Schicksal headquarters. As things stand, this will be a completely new situation.

"That's it."

Accelerator exhaled a breath through his nose.

That's enough for the number one monster.

"After that, it's all up to you."

"Huh…?"

"What do you mean by this...?"

Fu Hua and Theresa were both stunned.

Immediately afterwards, Hatsune Miku, having finished other things on the other side, slowly walked over.

"Is everything ready?"

"Ah."

The girl nodded slightly.

But her expression showed some hesitation.

"Don't overthink it... This isn't our business, is it?"

"…Um."

Regardless, after some hesitation, Hatsune Miku eventually walked to his side.

What is this... to do?

“...Um, everyone on the Hyperion.”

Hatsune Miku looked at everyone in front of her.

"I, um...we plan to...leave this place later."

"Okay, I understand. Then hurry back... Hey?"

Theresa, who had thought she had predicted the outcome, was immediately taken aback.

"Leave? You, you mean you're leaving the Hyperion?"

"Why? And why at a time like this... It's very dangerous outside!"

For everyone in the Far East branch, going out alone carries the risk of being captured by the Destiny organization.

But this is not the case for the strong.

"Isn't that exactly what I wanted?"

The expression on Accelerator's face was not one of fear.

That was a hideous smile, a smile of unfulfilled desire.

"I'm just wondering where that blond bastard is. If he dares to come to me, wouldn't he be easy prey?"

"Eh? This, this..."

"Huh? You guys don't actually think we're saying this with the intention of deliberately going out to our deaths, do you?"

The first one pursed his lips somewhat unhappily, as if he had been completely looked down upon.

"Completely unnecessary."

"But—if you're going out, what exactly do you plan to do...?"

"You wouldn't understand even if I explained. In short, it has absolutely nothing to do with what you're doing, and it won't hinder you at all. Just don't worry about me, understand?"

Regardless of the circumstances, Accelerator's decision is set in stone.

Not far away, Raiden Mei and Bronya, who had just emerged from the Hyperion, also heard about these events and couldn't help but exchange glances.

"...If, if I remember correctly, several years ago, the person who stopped me from clashing with the Hyperion in Changkong City—"

"have nothing to say."

Instead, the first one interrupted Raiden Mei before she could say what she was about to say.

"I just couldn't stand guys who were simply controlled by power... But things are different now, aren't they?"

"You are now qualified enough to control your own power, and there is absolutely no need for you to rely on the power of others to stop yourself. Knowing this is more than enough, isn't it?"

The black-haired girl standing in front of him was slightly taken aback, unsure of how to respond.

But no matter what, what she always held in her eyes was an unwavering belief.

Having witnessed all of this, the first person had nothing more to say.

He turned around.

"Wait, wait a minute—!!!"

"...Again?"

Accelerator could only turn around impatiently again.

The white-haired girl who had just woken up walked out of the room.

The girl with the same hair color as me.

"that…"

Normally a cheerful and spirited girl, she seemed to have undergone a complete personality change at this moment.

She looked at herself with a complicated expression.

"Thank you for stopping me."

"Perhaps this is not an important matter to you, or even just a trivial matter, but even so, I want to say thank you, thank you so much for stopping me."

This should be Kiana's most serious speech ever.

"I... I simply cannot imagine what the consequences would have been if I had actually used my body to harm the people around me back then..."

Even if the consciousness at that time wasn't hers, but the Second Herrscher, Kiana absolutely couldn't imagine what it would be like for the other party to use her body to take away her most important loved one.

Perhaps Theresa will be injured, Mei will be seriously injured, and Himeko Murata, who directly fights her, may even die...

But none of this will ever come to pass.

All possible tragedies, and all their paths, have been completely stopped by the person in front of him.

"Thank you so much...!!"

The most sincere words ever spoken.

The girl stared intently at him, as if she had thought of something.

"My name is Kiana, Kiana Kaslana."

"Tsk."

"We met each other about two years ago. This time... could you tell me your name... and tell everyone else?"

Not just Kiana.

Everyone on the Hyperion: Fu Hua, Himeko Murata, Theresa, Bronya, Raiden Mei, Tesla who had just rushed out of the room, Einstein, and Wendy.

Everyone was watching him.

The number one in Academy City turned his head away calmly.

"One-way passage".

The four-word title echoed in the girls' ears.

"In the end, there's not much to say in small talk... but there is one thing I want to tell you, which is a useless piece of nonsense."

Together with the girl with the blue twin ponytail beside her, they walked to the beach on the island.

He spoke without turning his head, word by word.

"...You guys really aren't cut out to be heroes, kid."

After a while.

The sound of the wind exploded.

A few seconds later, a loud bang rang out, and the moment the sound barrier was broken, everyone looked towards the front of the island.

There's nothing left there.
