Mecha-Kai species in Dimensional Travel

Still in her disguised state, Xiu Er rubbed her forehead with a troubled expression.

Taking the time back to before...

After ending the vacation she had granted herself, Xiu Er immediately decided on her next target—the Wind Spirits, the Yamai Sisters.

At the same time she made her decision, she began synchronizing with nationwide surveillance to locate them.

This method was foolproof; in modern society, there was no one Xiu Er could not find.

In the end, she found the traces of the two sisters as quickly as she had before.

On the surveillance feed, the two were currently at the venue of a competitive eating contest, and judging by the crowd's positioning, they were contestants.

It seemed that this time, the two had chosen this event to decide the winner between them.

Having obtained the target's location, Xiu Er did not hesitate. She directly used One-Way Street to open a Space Gate, appearing in an empty alley near the eating contest before blending into the audience.

After waiting for quite some time, the contestants fell one by one, leaving only the Yamai Sisters standing.

The final result was that both collapsed at the same time, with the organizers declaring them co-winners.

Just like that, their duel ended in a draw once again.

As the crowd dispersed, the Yamai Sisters each clutched their overstuffed stomachs, leaning on each other as they left the area.

Just as they reached a secluded spot, Xiu Er stepped in and blocked their path.

Faced with this strange girl blocking their way, the Yamai Sisters stopped and curiously observed her.

At this moment, the sister with the better figure and a slightly lethargic demeanor, Yuzuru Yamai, looked toward Kaguya Yamai.

"Question: Is this an acquaintance of yours, Kaguya?"

"How could that be?!"

"Besides, we are always together. If I had contacted anyone, would you not know?"

Kaguya hurriedly denied it, and Yuzuru, who was staring at her, did not say much more. After all, the facts were just as Kaguya said; if she had contacted anyone, it would be impossible for her not to know.

"Hmm... That is true."

The two looked at Xiu Er again, as if waiting to hear what she had to say.

"[Question] Are you Yuzuru Yamai and Kaguya Yamai?"

Hearing Xiu Er's words, the two widened their eyes slightly.

Since they had just won the eating contest, the organizers had announced the winners' names, so it was not strange for someone to know who they were.

However, when the strange girl in front of them asked the question, they both felt an inexplicable sense of dissonance from her.

Yuzuru frowned slightly.

"Affirmation: That is us. What business do you have with us?"

They knew of factions like the AST that harbored clear hatred toward Spirits, and those people had a very hostile attitude.

While this person in front of them gave off a somewhat eerie vibe, she had not attacked them outright.

Therefore, Yuzuru chose to communicate.

Faced with Yuzuru's inquiry, Xiu Er felt a hint of surprise.

Based on her previous experiences:

Princess Tohka had chosen to attack immediately after their conversation; Hermit Yoshino had chosen to flee the moment she saw her; Witch Natsumi had thought of using her Angel to control her the moment she asked that question; and Nightmare Kurumi had treated her as an enemy from the start.

But now, the Berserkers, the Yamai Sisters, had chosen to talk to her despite remaining vigilant.

"[Answer] My goal is to challenge you. I hope you will accept my challenge."

Hearing Xiu Er's statement, Kaguya's reaction was significantly stronger than Yuzuru's.

They realized that Xiu Er was one of those people, and that she knew their identities.

But what they didn't expect was that this person would have the audacity to challenge both of them alone.

"Ha? Challenge me? Where do you get such confidence?"

"[Answer] Not you, but both of you."

"Fine, but what is your goal? I don't believe you are just here to challenge us."

Yuzuru rarely abandoned her usual way of speaking, instead staring seriously into Xiu Er's eyes, trying to discern something from them.

"[Answer] I want to see the power of your Angels with my own eyes."

"[Supplement] Let's make 'whoever defeats me first' the content of your duel."

When Xiu Er threw out this proposal, the Yamai Sisters' attitudes wavered.

Before Yuzuru could say anything more, Kaguya had already made her stance clear.

"Hey Yuzuru, since she is arrogant enough to want to see our power, let's satisfy her."

At this moment, a growing fighting spirit could be seen in her eyes.

Seeing her sister's attitude, Yuzuru Yamai said nothing more.

"Good."

Seeing that both had agreed, Xiu Er did not hesitate, directly using [One-Way Street] to teleport the three of them to an isolated island he had chosen in advance.

And this led to the scene at the beginning.

Chapter 13: The Approaching Storm

"Ate too much, let's have some post-meal exercise to help with digestion."

These were their exact words.

Since the other party had readily agreed to his request, he would naturally return the favor with respect.

So, what should they do? He took a look at the current environment.

Isolated island, beach, ocean.

Right, decided. Beach volleyball it is.

And so, Xiu Er found himself confusedly acting as the referee.

When Xiu Er had just teleported the Yamai Sisters here, his disguise naturally collapsed due to the use of his armaments.

Several circular rings were projected above his head by the disc-shaped mechanical device, his once-lively amber eyes turned into lifeless mechanical cameras, and the supple, elastic skin he previously possessed reverted to hard machinery.

Yet, when the two sisters saw Xiu Er's non-human appearance, they showed little surprise, instead wearing expressions that said, "As expected."

"So you really are the [Spirit Hunter] that has been appearing recently."

Although it was phrased as a question, the way Yuzuru Yamai said it made it sound like a confirmed fact.

Spirit Hunter?

What was that?

At this moment, back in his original form, there was no expression on Xiu Er's face, but an emotion called "confusion" emerged within him.

He immediately went online to search, the golden fluorescent light flickering within the operating device atop his head.

This was the result of his modifications; ever since he connected to this country's network, he had begun tinkering with the device on his head.

Aside from the [Dimensional Device] added by the system, Xiu Er had also installed many strange little plugins, along with mobile phone functions.

Now, Xiu Er could play music, make calls, and even project short videos from the device on his head.

Back to the main topic.

Let us return to the present—

Finally, after Kaguya Yamai delivered a spike that Yuzuru Yamai failed to receive, causing it to land within the lines, Xiu Er immediately blew the whistle (the whistle sound emitted from the mechanical device on his head).

Under the disguise of the Fake Demoness, as long as he did not use his armaments or get attacked, simply running the device would not cause the disguise to collapse.

"Winner: Kaguya Yamai."

According to Xiu Er's accurate records, Kaguya Yamai had reached the target score first and won.

"Complaint: I will definitely win next time."

Xiu Er watched the interaction between the Yamai Sisters and silently picked up the volleyball that had been tossed onto the ground.

Based on his observations, this ball had been protected by the Yamai Sisters' spirit power, otherwise, it would have exploded on the very first hit.

Relying on the residual spirit power on the ball, Xiu Er successfully recorded the Yamai Sisters on his detector.

"[Question] May we begin fulfilling the promise?"

"Fine, fine, fine. Let us show you our power."

"Affirmation: We will not hold back."

After speaking, the energy levels of the Yamai Sisters on Xiu Er's Energy Detector began to rise gradually.

Violent gales suddenly erupted with the Yamai Sisters at the center, and the two slowly floated into the sky accompanied by the wind. Amidst the storm, their attire underwent a transformation.

Xiu Er simply stood where he was, his long hair reaching the ground swaying wantonly in the wind; other than that, he stood firm in the gale, unaffected by any external forces.

He simply and silently deactivated his disguise.

"-[Codex Opening]-[Pseudo-Codex]-[Gokurokugai]-"

Pseudo-Gokurokugai was the first armament Xiu Er obtained in this world and his most frequently used one. There was no special reason for this; it was simply easy to use.

At this moment, the Yamai Sisters high in the sky had also completed their transformation.

Now, the two had returned to their original Spirit Dress, both wearing restraint suits of different colors, sexy and slightly revealing.

On each of their shoulders, symmetrically placed, was an inorganic structure shaped like wings; the mechanical wings provided an exotic beauty.

A pitch-black chain with a diamond-shaped blade at the tip appeared beside Yuzuru Yamai; that was the Angel she possessed as the clone, Hurricane Knight - Binder.

In contrast, Kaguya Yamai also displayed her Angel, Hurricane Knight - Piercer; a giant assault rifle with a length far exceeding the user's height appeared in her hands.

Now, both sides were prepared.

Xiu Er had been quietly analyzing data ever since the Yamai Sisters brought out their respective Angels.

Kaguya Yamai was the first to launch an attack.

She raised the piercing weapon in her hands, its tip pointed directly at Xiu Er, and dove toward her target from high in the sky. Propelled by the wind, her speed soared; if she were to land a hit, the target would likely experience a heart-piercing chill on the spot.

Facing the incoming Kaguya, Xiu Er could have easily dodged.

If nothing else, when it came to speed, Xiu Er dared to claim that the wind spirit opposite her could not keep up with her.

After using Speed Violation, the original energy consumption issue was gone, allowing her to inject energy into her armaments without restraint to maximize her own speed.

However, to analyze the opponent's Angel, she still needed to experience the specific numerical power at close range.

And so...

"—Codex Opening—No Passage—"

As Xiu Er deployed her shield to prepare for the attack in front of her, she discovered a pitch-black chain behind her back, striking toward her at a speed even faster than Kaguya's.

This direction should have been a blind spot in a human's field of vision; without rich combat experience or monstrous intuition, one would absolutely be drawn in by the frontal attack and ignore the sneak attack from the rear.

But for Xiu Er, who was of the Mecha-Kai species, such tactics were completely ineffective.

The two sisters' coordination was quite decent; they didn't need to say anything to each other. As the people who understood each other best, they shared a telepathic connection.

BOOM—!!!

The tip of the spear made contact with the shield.
