Editing Unlimited Fafnir:Volume 10 Chapter 2 (section)

===Part 2===

"Ariella-chan is about to arrive."

Looking at the partition that blocked the passage, Iris said nervously.

"That's right—our opponent seems to be a high-speed assault unit. Although their specific identities can't be confirmed due to destruction of security cameras... It should be Ariella."

I explained what I had heard from Charlotte and added my own hunch while sweeping my gaze across the surroundings.

This was an underground passage near the surface. It was relatively wide with higher ceilings due to being used as a transportation passage for moving goods and materials. Although it looked like large weapons could also pass through, it was unlikely that the unmanned weaponry and NIFL soldiers could arrive faster than Ariella.

Currently, NIFL was stuck with infighting. The foot soldiers were being blocked and attacked by people under Charlotte's control while the unmanned weapons were getting hacked one after another by Tia and used to obstruct other unmanned weapons.

Due to comparable numbers on both sides, it was currently a stalemate. However, there was no one in those NIFL units who could oppose the Ds, who each individually wielded firepower on the level of large weapons. As a result, the first to arrive ought to be Ariella.

"Mm..."

Beside me, Ren gripped my shirt tightly.

She looked quite nervous but there was no uncertainty in her eyes. Ren's face conveyed the determination to rescue Ariella. She was staring at the partition.

"It'll be fine for sure! Tia is here!"

Tia encouraged us.

Even capable of hacking dark matter, Tia was honestly very reliable. Perhaps the ground defense situation might get tougher due to Tia's withdrawal, but Lisa and Firill had stayed behind to maintain barriers with their full effort.

"—Mm."

Ren's expression relaxed slightly as she nodded lightly in gratitude.

"If Ariella-san is bringing many NIFL soldiers... What shall we do?"

Mitsuki had already summoned her fictional armament of a bow when she asked me the question. Judging from her demeanor, her body temperature was still raised but she sounded very energetic.

"An increase of numbers would result in loss of marching speed. Judging from their invasion speed, a small team is more than likely. Well, it's possible for unmanned weapons to be following them, but that should pose no threat."

Listening to me, Kili nodded calmly.

"That's right, Tia can hack them. Rather, it would only serve to increase our numbers. Ordinary soldiers can't do anything once we envelop them in wind. It makes no difference no matter how many of them come."

Although Kili's reply was confident as usual, there was something slightly different.

"......"

She frowned in surprise when I stared at her in amazement.

"What's wrong?"

"Nothing, I'm just a bit surprised you're thinking of neutralizing instead of killing them."

Normally, the pattern would be her saying "just incinerate them" and me trying to stop her.

"...I'm just playing along with your methods. Unnecessary arguments are a pain."

Kili averted eye contact with some displeasure then Iris suddenly looked at us.

"Mononobe, don't speak like that! Kili-chan is being considerate for us, so we should thank her!"

"Oh right... That's true. Thank you, Kili."

Scolded by Iris, I thanked Kili.

"Huh? Hmm, well... It's nothing—By the way, Iris-chan, don't make unnecessary comments, you're throwing me off balance..."

Kili wavered in a rare moment. To regain control, she took a deep breath forcefully.

The ones present here were me, Ren, Iris, Mitsuki, Kili and Tia, the six of us. Lisa and Firill on the ground to bolster defenses. Jeanne, Shion and Vritra were staying in Charlotte's room.

"Putting all that aside—How do you lot intend to stop Ariella Lu? We should discuss the battle plan properly now, right?"

Hearing Kili's question, I looked at Mitsuki, who then nodded lightly.

She seemed to be leaving the matter to me. Although I had already pondered the issue, I asked Tia a question first before sharing my thoughts.

"—Tia, how wide a range can you interfere with dark matter?"

"Around ten meters, but for short periods, Tia can expand the interference range by generating electricity."

After listening to Tia's answer, I crossed my arms and said:

"Ten meters—even if it could be extended, this distance isn't very reassuring. Before we find out enemy numbers and how they're equipped, you should stay in the back on standby. Once the partition is destroyed, I'll go over first to draw attention and engage Ariella."

"Yes!"

Tia nodded and accepted my instructions. However, Ren looked up worriedly from beside me.

"Onii-chan..."

"Don't worry. I won't get taken out so easily. This battle's purpose is to save Ariella. Also... If the promise still holds, all I need to do is touch Ariella once."

To ease Ren, I stroked her head gently while I answered.

If I were to touch Ariella, she would "transform into my kind." Ariella had told me to try turning her into my mate if I wanted to stop her.

"Then Mononobe, what about me? I'm willing to do anything for Ariella-chan!"

Listening to our dialogue, Iris asked, fully motivated.

"Iris, you'll stay on standby next to Tia and use explosions to pin down approaching enemies. No need to hit them directly. Just use the wind from the blast to stop them from getting close."

"Yes, I got it!"

Iris answered energetically. Next, I issued instructions to the others successively.

"Mitsuki, you'll be in charge of guarding Tia and Iris. If things go south for me, take Tia and Iris and move them to bring Ariella into interference range. But depending on the situation, you might need to keep a barrier deployed—"

"Understood. Leave Tia-san and Iris-san to me."

Mitsuki accepted my orders with a tense expression.

"Kili, you'll head to the front with me. I'm leaving everyone apart from Ariella to you. Just as you said earlier, just neutralize them without killing anyone."

"...Sure, I'll try."

Was she displeased about what I brought up earlier? Kili nodded with a mixed expression. Finally, I looked at Ren.

"Ren, you'll be in charge of the middle guard. Prioritize your own safety while supporting Kili and me. Also, if possible, I hope you can try calling out to Ariella."

"Mm!"

Ren released my shirt and left me. With a determined expression, she nodded.

—Znnnnnnnn...

At this moment, a deep rumbling noise was heard coming from the front.

"...Seems like they're approaching. Keep away from the partition and prepare to fight, everyone."

Giving these orders, I backed away together with everyone.

As the vanguard, Kili and I stopped a couple meters away from the partition. In charge of support as the middle guard, Ren retreated slightly farther back. The trio of Tia, Iris and Mitsuki backed away the farthest with their fictional armaments ready. The spot where Kili and I were standing was precisely the limit of Tia's interference range.

The low rumbling was heard again.

It sounded nearer than before. One by one, the partitions were being destroyed.

"Finally a chance to fight alongside you. Although our first shared endeavor was supposed to have been completed last night... Oh well, this is more like our style."

Kili tossed her long black hair and smiled with satisfaction.

But as soon I thought back to the previous night's nocturnal visit, blood rushed directly to my face.

"—Quit making weird comments before a battle. Also... Give me a break on that kind of stuff."

While whispering quietly, I glanced secretly at Iris and Mitsuki to see if they had heard.

"No. I said we're continuing next time, didn't I? Also, you've heard about Neun from Mother and Tia, right?"

After refusing to comply, Kili asked solemnly.

Indeed, I had heard about authorities, counterdragons and calamities from Tia and Vritra. Kili probably knew some of it from Vritra too.

"That's right—But Vritra insists I'm not Neun."

Neun was the newest counterdragon born from the world to resist the inevitable coming of the ninth calamity—the ninth dragon. However, it would be quite strange if I had become Neun without encountering the calamity already. That was what Vritra said. Furthermore, since the ninth calamity was apparently the "true form" of the seventh calamity, the chances of an authority arising to counter it were quite low to begin with.

"Mother is too pessimistic. Oh well, it can't be helped since she witnessed the world's destruction once. But we're not obliged to listen to her. Stop thinking too much and just make babies happily with me."

"M-Making babies, you..."

My face instantly turned boiling hot as a result of Kili's direct proposal.

"Oh my, what's the problem? If we have babies, it'll increase the number of antibodies for countering the ninth calamity. Isn't this necessary for the sake of all life on the planet?"

"Uh..."

My mind was unable to keep up with this kind of big reasoning, but a that moment, a third impact was heard.

"L-Let's talk about this some other time. That shaking just now—I'm guessing the nearest partition has been destroyed. Kili, can you deploy barriers to prepare against the partition exploding?"

I changed the subject forcibly. Kili sighed lightly and nodded.

"—Then we'll continue the discussion in your bedroom."

Smiling, Kili said something disturbing before raising her hand.

Wind brushed against my cheeks while the surrounding temperature increased. Although invisible, tiny particles of dark matter must have been generated by Kili in the surroundings. This was her prided skill of "Muspelheim." By spreading dark matter within an area, she was able to perform transmutation instantly without any warning motions for opponents to notice.

"Construction of dual barriers of heat and wind complete. Although this can block the explosion's wake, remember to give me a signal when you're charging into enemy ranks. You'll be burned to death if you touch the heat barrier."

"Yeah, I got it."

I nodded and focused my awareness on the other side of the partition. Although the thick and heavy wall blocked the majority of information, I still felt myself breaking out in goosebumps.

Sharp murderous intent, akin to a knife against one's throat, was approaching step by step.

Kili also seemed to sense the same thing as I did. The smile vanished from her face.

"Since it seems like it'll be more dangerous than I imagined, I'll give you a warning. Don't count on my biogenic transmutation too much."

Kili said in a stiff voice. When I looked at her questioningly, she made a light shrug.

"Although my biogenic transmutation can heal wounds, my own body is the only thing I can restore perfectly. When applied to other people, the most I can do is 'overwrite' the wound."

"Like deleting an injury?"

"When repairing major damage—like restoring entire limbs or organs—will usually result in rejection. I don't have any way of recreating someone else's body correctly."

Kili answered then glanced at Iris and the girls behind her.

"That's why you must protect Iris-chan and the others properly if anything happens. You can't go for mutual destruction yourself either."

Listening to her warning, I smiled subtly.

"What are you laughing at?"

"Hmm, I couldn't help it when I realized you're worrying about Iris and the others."

"What... I'm not—"

Seeing Kili in a fluster, I smiled and thanked her.

"Thank you, Kili. But don't do anything reckless either, Kili. Even if you can heal wounds, it's over if you die directly."

"...I know that. But it's true that I don't die easily. If I cover you—"

Kili replied slightly displeased, but stopped mid-sentence.

With bated breath, she was staring at a black sphere that had appeared ahead.

It was dark matter that every D could generate.

However, I had not summoned it. Judging from the look on her face, Kili had not summoned it either.

Then was this summoned by Iris or the others behind us, or was it—

I could not help but feel my hair standing on end. The partition was intact. The invading party was still on the other side.

However, they had Ariella on their side. If she had noticed our presence on the opposite side of the partition and generated dark matter, guided by intuition—

Also, this dark matter happened to be just outside of Tia's interference range.

"Kili!"

"Don't!!"

I reached out to protect Kili but my hand was redirected and my entire body was shoved away.

Just as I was pushed to the ground, the dark matter gave off blinding light.

—BOOM!!

Flames spread from the explosion. Kili was swallowed by them.

At the same time, a strange noise was produced at the partition. Was it because Kili's barriers had vanished? The flames and the partition's remains rushed over unimpeded. There was no time even to stand up.

Fictional armament—Siegfried.

I summoned the ornamental gun of a fictional armament into my left hand, aiming the muzzle at the flames and debris. However, I heard Ren's voice just before I performed transmutation.

"Onii-chan!!"

The air she generated formed a violent storm rushing over my head.

The storm blocked the flame and debris flying at me, causing a scattering of black smoke.

Several shimmering silhouettes appeared on the other side of the smoke. Seeing them, I instantly got up and charged.

"Ren, take Kili and back away!"

I had no time to check on Kili's condition after she was swallowed by the explosion. I could only pray for her survival and leave things to Ren while charging into the thick smoke.

This attack was probably Ariella's. I closed in. Unless I kept Ariella occupied, there would be no way to buy time for Kili to retreat to the back.

I cleared my mind and gathered as much information from the five senses as possible.

Shimmering silhouettes amidst the smoke. Sound of footsteps. The smell of gunpowder, drifting in the air. The motion of air brushing against my skin.

The number of enemies—Eight of them. No sound of driven machinery or the scent of exhaust gases. In that case, all of them were human.

Despite the poor visibility, it was not difficult to get a grasp on the numbers and positions of my opponents.

As long as I seized initiative, I could handle this number of enemies single-handedly.

Anti-personnel weapon—AT Nergal.

Using transmutation, I created a projectile-based stun gun in my empty right hand. Aiming at the eight presences, I fired consecutively.

Ariella might be able to dodge, but the remaining seven should be neutralized.

Just as I was thinking that, I heard the sound of deflected electricity. There were also several overlapping instances of high-pitched metallic ringing.

This sound—I had heard it before. During my fight against Ariella underground earlier, the same sound had resulted when she threw her knife to block Nergal's bullet.

And right now, this sound was coming from ''eight directions simultaneously''.

"—"

Instinctively sensing danger, I immediately jumped from where I was standing. Silver knives stabbed my former location.

A total of eight. In other words, every single one of Nergal's targets had deflected the bullet and counterattacked.

Although my plan was to find out which one of them was Ariella, it did not work. All I could confirm was that all eight were extraordinary opponents.

To be able to deflect bullets in such poor visibility conditions, their skills and instincts were beyond common sense.

It was not possible to reach such a realm unless they possessed a certain "something" surpassing humans.

I called it "Fafnir." I had sensed something similar in Ariella and Hreidmar. Based on the number of opponents, the thought of Sleipnir flashed through my mind. However, it was hard to imagine all of them reaching such a level.

—In that case, perhaps all seven of them apart from Ariella were Hreidmars?

I recalled the soldiers clad in silver armor but was struck by a sense of dissonance. Back when I was detecting enemy presences earlier, I had not heard the metallic sound special to armored clothing. Furthermore, the armored outfits would insulate against Nergal's electroshock attack, eschewing the need to defend.

In any case, no amount of thinking on my end now would reach a conclusion. Since the smoke blocking the view was not working, it was acting as a disadvantage to my own side instead. Under such conditions, neither Mitsuki nor Ren would be able to provide cover fire.

"Air Bullet!"

Aiming the fictional armament in my left hand at my feet, I released a relatively mildly compressed bullet of air.

A whirlwind began to blow with me as the center.

With that, I was able to defend against follow-up knife attacks while ensuring visibility, killing two birds with one stone. If it succeeded in throwing my opponents off-balance, I could even shoot them with Nergal.

"...!?"

Just as I predicted, Ariella was among those people. With a somewhat hollow expression, she stared intently at me.

However, the rest of them were not Hreidmars. The possibility I had ruled out just now—the special forces unit I used to manage as their captain—the young soldiers of Sleipnir were on the other side.

Although they were still the people I knew so well, the entire team's ambiance had changed. Their faces were as blank as Ariella's with only intense desire to kill residing in their eyes.

"Onee-chan!!"

Ren cried out from the back.

"Ariella-chan!"

"Ariella-san!"

"Tia doesn't want to fight you, Ariella!"

Iris, Mitsuki and Tia also called out, but Ariella's expression did not change at all. Rather than ignoring them, it seemed more like she had not heard. She was clearly behaving strangely.

I did not know what had happened to Ariella but right now, I had to subdue her according to the battle plan.

"Ariella!"

To draw her attention, I called her name while kicking the ground to charge. Then using the lingering wind's momentum, I closed in on her in one breath.

Ariella turned her arm. Held in her hand was a silver knife.

I recalled how she had sliced my Nergal in half with her knife in the previous battle. Ariella's knife should be made of mithril. There was no way to overcome it with brute force.

"Red Bullet!"

Hence, I used the remaining dark matter, converting all of it into a blade of air.

The highly compressed blade turned scorching hot, slashing through the air with a red trail.

Ariella swung her knife at my head without hesitation.

Clang!!

A heavy impact was heard in the clash between metal and compressed air.

Her attack was quite fierce but easy to handle. Power was the only thing required to break through compressed air. A metal's hardness and sharpness made no difference.

One more step and I could reach out to touch Ariella. Sleipnir's soldiers were some distance away. Now was a perfect chance.

The dragon mark on my left hand began to pulsate while faint blue light spread out.

However, the moment just as I was about to take this final step, I felt a chill. I was currently on the boundary of life and death. Heeding instinct, I turned and retreated.

A sharp sound zoomed past. Something had brushed across the tip of my nose. Noticing the slight scattering of my bangs, I realized something had severed them. However, I did not find anything apart from knives.

I looked at the direction of the attack's source, only to see a young man there with arm raised. The remaining six also raised their arms. Next to their hands were hovering pitch-black spheres.

"What—"

This unbelievable scene made me gasp. I jumped backwards.

Next, invisible slashes flew past before my eyes, accompanied by the sound of wind slicing. The ground was cut open deeply while wind struck my face. The black spheres disappeared from the young men's hands.

—The move just now consisted of attacks launched using the transmutation of dark matter? How could that be possible...!?

Every member of Sleipnir was male. Was it possible that all of them had concealed their gender like Jeanne, but were actually Ds?

The seven young soldiers attacked me during my state of confusion. They were each holding a silver knife identical to Ariella's.

I fired Nergal to restrain and slow down the few of them approaching from the right side. At the same time, I shot the left side with consecutive bullets of air blades, the same as what I had used in the beginning.

That movement just now—This knife handling—

According to what I knew about him—Robin—he did not fight this way. Disliking close quarters combat, his forte was supposed to be using firearms to fight at mid range.

It was almost like a different person... Or rather, this was too similar to Ariella earlier.

The second and third people attacked in succession—Otr and Regin—I dodged in the nick of them, but sure enough, their movements were the same as Ariella's.

Although close quarters combat was their strength, their original traits could not have changed completely. Otr specialized in strength and Regin in skill. Their characteristics were very obvious. But right now, their movements were abnormally similar.

Using Nergal, I had pinned down the remaining four from advancing—Sigurd, Lancelot, Kunato and Nataku. As though synchronized with Ariella, they all raised their hands.

Seeing the generated dark matter, I became aware that I had not imagined what I saw earlier. For some unknown reason, they had obtained the power to generate dark matter.

In that case, it was like fighting against eight Ariellas.

It was impossible to find a chance of victory without killing anyone when the number of equal opponents increased to eight.

—However, that was assuming I was alone.

My dragon mark began to heat up.

Why was that? I knew without looking behind that "she" was going to aid me.

"Laevateinn!"

Ariella and the young men stopped attacking and jumped to the side. Immediately after that, a flash of red light swept across the passage.

Seizing the chance, I distanced myself from Ariella and Sleipnir to regroup.

"Yuu!"

Next, Kili stood by my side. Although her clothing was charred, she did not look injured.

"Are you okay?"

"Yes—before getting attacked, I used Muspelheim to detonate an explosion. The two explosions cancelled each other out."

Kili smiled with composure and looked at Ariella's group.

"You're reckless as ever... Did you get injured?"

Considering the barriers had disappeared, I knew she must have lost consciousness for a moment at least.

"I healed using biogenic transmutation. In any case, there's no problem. Never mind that, what do we do next? Things have gotten super annoying if all of them are Ds. They're probably on guard against Tia too."

Kili motioned with her eyes towards Ariella's group, which had stopped attacking, and commented seriously.

While talking, we slowly continued to distance ourselves from Ariella's group. Currently, we had already retreated to within Tia's interference range.

If possible, I would like to lure Ariella and the others into Tia's interference range, but it could be difficult depending on the situation.

"No... It's impossible for them all to be Ds. First of all, they're all guys... Having lived as roommates, I can assert with certainty. There must be some kind of reason for this."

"—Yes, I agree, because I would be troubled if there existed others sharing your special exception. There is no value except in scarcity."

Kili shrugged.

Instead of coming over, Ariella and Sleipnir scattered in the wide passage. As expected, none of them stepped into the interference zone.

Tia was using electricity to interfere. Although invisible to the eye, Ariella and her group could probably detect Tia's deployed electromagnetic domain with their sharp senses.

"......"

Ariella silently raised her hand towards us. Next, the young men did the same in unison.

"Nii-san, we will expand the barrier!"

I heard Mitsuki's voice from behind. A gust of wind blew over, probably from Mitsuki expanding the air barrier protecting Tia and company, allowing it to reach where Kili and I were standing.

After that, Ariella's group used the dark matter generated by their hands to fire jets of flame at me.

But blocked by the barrier of air, they exploded mid flight.

Sure enough, it looked like they were all capable of using dark matter. However, ''supposing this fact could not possibly be true''—

Only an exceedingly clear and simple conclusion could be deduced. After I finished checking this conjecture in my mind, Ren ran forward to me.

"...Onii-chan! Why... Onee-chan—this is, so weird!"

Ren's sense of dissonance was even stronger than mine. She was speaking with a very pale face.

"Yeah, rather than having committed herself to some kind of resolve—It seems more like she's lost her sanity."

Looking at Ariella on the other side of the flaming explosion, I nodded at Ren.

"...What can we do? Onii-chan, what can we..."

Ren stared hard at me. I wanted to reassure her with a pat on the head, but my hands were occupied right now with holding Nergal and a blade of air.

Hence, I looked into Ren's eyes and voiced my thoughts loudly, audible enough for others to hear.

"Ariella might have transformed."

"...Transformed?"

Uneasily, Ren repeated what I had said.

Ariella and her group continued to attack, but Mitsuki's deployed barrier was very secure. Currently, we had the time to exchange information.

"Hreidmar—those armored soldiers I've previously fought at the mountain villa and at the Principality of Erlia—was hollow inside. Only smoke filled the interior. According to my former superior officer, Major Loki, they had ''transformed as a result'' of obtaining power."

"Right—You've seen what's inside them."

Kili narrowed her eyes and whispered. Working together with Jeanne, she had also seen it at the Principality of Erlia before.

"Right now, the people with Ariella is also a unit belonging to Major Loki. Compared to the time when I was still with them, their vibes and ability levels are completely different. It's possible that they've transformed as a price for obtaining a power similar to Hreidmar's."

"The price of power..."

Iris murmured softly.

Having gone through a transformation of her physical body due to Basilisk's authority, Iris had experienced what it was like. Last time, Major Loki had brought up Hreidmar's situation to illustrate a point about dragons.

From what I had heard from Charlotte, Major Loki was the descendant of the man who possessed ''the authority born for the sake of killing humanity''. If this authority truly existed and Major Loki had the technology to make other people inherit it... Then everything could be connected together.

The clear dragon—"Colorless" Fafnir.

Hreidmar, Sleipnir, Ariella, and me as well—Most likely, we all held this authority.

Major Loki had said that true value lay in the ability to obtain power without transforming—And that was me. Hence, among those who had obtained the authority, I was the only one bestowed with the codename of "Fafnir."

Conversely, it implied that everyone else apart from me had transformed. However—

"Don't worry, Iris."

Without looking back, I declared strongly.

"Mononobe...?"

"If obtaining power causes transformations, there must be a way to turn back. All I need to do is repeat what I did to turn you back to human, Iris."

"Oh—"

Hearing what I said, Iris took a deep breath.

"Nii-san, I now know your intentions."

"Tia knows too!"

Mitsuki and Tia realized what I was trying to say.

However, there was something I had to tell them.

"However, there's no way I can decide the match unless I fight the current Ariella and her team with the intent to kill. But since I don't plan on 'killing' Ariella, there's absolutely no way for me to win while facing the uncertainty of what the other side will transmute using dark matter."

"What... Wait, Yuu!"

Kili glared at me angrily but I gave her a look to tell her to wait for me to finish.

"Be that as it may, I don't need to win. All I need to do is touch Ariella with my fingertip. With that, she'd surely recover her sanity. That's why, I'll be counting on you girls to cover me so that I can reach Ariella before I get killed."

I said that while moving towards the edge of the barrier where Ariella's group was attacking.

"Wait! If we do not discuss properly beforehand, we might end up obstructing you, Nii-san—"

Mitsuki called out anxiously to stop me, but I shook my head to tell her it was fine.

"Don't worry, Mitsuki. You'll act suitably when I feel it's necessary. I know this from a feeling. It'll tell me how all of you will take action, Mitsuki."

"Even if you know, this is still too..."

Mitsuki grumbled in protest. At this moment, Kili interjected.

"I believe in Yuu. When covering him just now, well—although I hate to use the word 'feeling'—I felt as though Yuu and I were joined as though of one mind. You felt the same way, right?"

I nodded at Kili's question.

"Yeah, I knew Kili would help me. Perhaps, there's some kind of link because we've become 'the same kind.'"

"In that case, Tia can definitely do it! Tia is already Yuu's wife, we can surely connect our hearts together through the bond of husband and wife!"

A competitive flame had apparently been lit in Tia's mind.

"Ehhh!? Tia-chan, it's too early to talk about husband and wife! But... I've had this feeling of connected minds too. When Mononobe selected me, a strong wave of feelings were transmitted."

Seeing Iris agreeing with Kili too, Mitsuki showed displeasure in her expression.

"Speaking of bonds with Nii-san, mine should be the strongest. Very well—I understand. Till Nii-san reaches Ariella-san's side, I shall absolutely protect him."

Next, everyone looked at Ren, who had yet to comment."

"Mm. Onii-chan... You've always known what I wanted to say even if I did not say it out. Hence, I believe in you, Onii-chan."

Ren gripped her hammer fictional armament tightly and accepted my battle plan.

"Thank you, Ren."

I smiled and looked at Ariella who was on the other side of the barrier.

"—Mitsuki, on my signal, release the barrier."

"Affirmative."

I replenished Nergal's ammunition in my right. Dispelling the blade of air in my left, I transmuted Siegfried.

Was Ariella's group trying to break through the barrier by force? Their attacks were escalating in intensity—However, this produced openings in the generation of dark matter.

Seizing the opportunity, I yelled.

"Mitsuki!"

The instant the attacks paused, I rushed out. With the barrier lowered, there was nothing to stop me anymore.

Ariella's group immediately reacted to my action and changed formation.

In the center, Ariella backed away while the young men flanked and surrounded me.

By throwing knives and transmuting dark matter from eight different directions, they attacked. Every strike was imbued with the intent to kill with certainty. A mortal wound would result no matter which attack landed.

"Antigravity!"

Using Siegfried to fire a dark matter bullet at my feet, I transmuted antigravitational matter.

Deployed with me at the center, a repulsive field deflected all attacks.

But after that, while I was running, dark matter appeared in my surroundings again.

"Tsk—"

This was the same tactic as what Iris had used to counter Leviathan's repulsive field. Attacking with dark matter directly within the field instead of from outside—

As expected, Ariella's group was currently more powerful than me. Naturally, there was a decisive gap between them, who possessed ''the authority born for killing humanity'', Ariella and company who were fighting to kill, versus me, fighting without murderous intent.

However, I had already declared I would rescue her from this hopeless situation, because I had heard the thoughts in her heart.

"—Come, come, fragments of the Far Beyond."

Even more dark matter appeared in my surroundings, but it was not generated by Ariella's party. It was created by the girl with super spatial perception who was able to exert precise control so long as explosions were the foregone conclusion.

"O raging wind, explode!"

The instant Ariella and her team's dark matter turned into exploding flames, Iris' acute voice rang out.

With the sound of an explosion, my view became blocked by black smoke, but I almost felt no impact against my body. As though it were the most natural thing in the world, I understood what Iris had done.

By making the air she had summoned explode, she had cancelled out Ariella's attack. It worked the same way as how Kili had protected herself earlier, but I received no damage at all despite my close proximity. This was evidence of perfect control of the explosion's directionality. Sure enough, Iris' talent was extremely outstanding in a most unconventional area.

At the same time, Mitsuki attacked the young soldiers.

"First Arrow—Forked Wind!"

Almost impossible to discern with the naked eye, the arrow of wind turned into countless arrows, shooting at them.

Normally speaking, it was impossible to evade, but I had braved through this move last time when I was having a disagreement with Mitsuki.

If I could do it back then, there was no reason why they could not do it now.

Like beasts, they moved between the invisible arrows. Simultaneously, they launched knives at me from unstable postures.

Continuing to advance towards Ariella, I moved slightly away from the repulsive field's zone of effect. There was very little dark matter remaining in Siegfried, insufficient to generate a strong repulsive field.

However, thanks to Mitsuki slowing them down, I received new support.

Boom—Several small projectiles of flame appeared in my surroundings, deflecting the knives away.

This was Kili's Muspelheim. By spreading out dark matter, too small for the naked eye to see, in the entire space, she was able to transmute heat at any location of her choosing.

However, this seemingly almighty barrier had a weakness. Ariella and company instantly acted in response.

Silently, they raised their hand to generate dark matter, transmuting it into white smoke.

Tiny particles of dark matter could be erased with the use of smoke. Muspelheim was neutralized as a result, but thanks to Ariella and company switching to defense, I received the chance to advance further.

I had pretty much figured out the pattern in how they generated dark matter. So far, they had all performed the same transmutation simultaneously. In that case, Ariella should be the one person capable of generating dark matter. All Ariella was doing was producing dark matter next to the young soldiers when they raised their hands.

If my speculation was correct, then there should be a delay until the next transmutation.

I was almost about to reach her.

"Yuu!"

"Onii-chan!"

Tia and Ren were the ones to buy me the time to close this gap.

Tia used lightning attacks to restrain the young soldiers while Ren made use of her massive generating capacity to create thick walls on my left and right.

My dragon mark pulsated.

Everyone's thoughts were transmitting through. I could sense their feelings. Right now, we were definitely linked together.

If this was the bond between those of my kind, there was nothing more encouraging than this.

I was not fighting alone.

Ariella—I won't let leave you behind either, all alone!

I closed in on her, extending my left hand that was holding Siegfried.

This time, I'll surely catch you. I will rescue you with this hand.

During the underground battle, I had used Ether Wind to sense Ariella's internal thoughts. Unable to stop herself, Ariella was definitely seeking help.

With a hollow expression, Ariella stared at me with eyes filled with intense killing intent and swung the knife in her hand.

It felt as though I could see an illusion of my left hand severed and my heart stabbed.

However, I ignored the warnings of instinct and pulled Siegfried's trigger.

"Ether Bullet!"

Using my fictional armament, I transmuted the remaining dark matter into golden particles, wrapping them around my left arm.

A heavy strike connected.

However, the silver blade slicing at my left arm was stopped by the golden particles.

When a living body was enveloped in concentrated Ether Wind, the soul inside would manifest. This manifested soul was immune to all physical interference.

This was a characteristic of Ether Wind that I had learned during the battle against Hraesvelgr.

Despite my lack of dark matter, it was still possible to envelope my left arm alone—I gambled on this.

Naturally, if it failed with my left arm getting severed, Ariella would probably take my life in the next strike.

In that instant, I was at least able to touch her with my fingertip.

I reached out to Ariella with my left hand, which could not move too freely after being enveloped in golden particles.

The instant my fingertip touched her forehead, the dragon mark on my left hand glowed blue—The golden particles linked our minds together.
