Key of Blanknees

Kouro blinked his eyes a few times before finally confirming that inside the treasure chest was indeed a Divine key, the Key of Blanknees.

Looking at the Divine key, he tried to remember how it worked.

The function of the Key of Blanknees is to allow the user to use the power of a Herrscher depending on the Herrscher core that is inserted.

This divine key was also the only Divine Key that does not use Herrscher cores as the main ingredient.

Kouro took out the Divine key before jumping out of the pit, he could now see the form of this Divine key.

The Key of Blanknees in his hand was in the form of a gray protective armor made of Soulium metal, there was a hole in the chest of the armor that seemed to be used to supplement the Herrscher core.

It's just that what caught his attention was that this form of armor was specifically for a man, not a woman.

Though from what Kouro remembered, the Key of Blanknees was only used once by a woman from the previous era, and after that, it was not used again...

That's because from what he remembered, using Herrscher's power directly like that was too taxing on the user.

So... Wouldn't it be better for Herrscher's core to be used as a weapon that could be used by MANTIS?

But now why is this Divine key here, especially for a man... Wasn't there a MANTIS who could see the future?

Staring at the divine key Kouro remembered that he had the core fragment of the Herrscher of the End... Hmm... Is it possible that he could use it?

Upon thinking this his curiosity was piqued, if he could use that Herrscher core shard wouldn't he become overpowered?!

But before that.

Kouro ran towards a place where the ground was flat and quieter, after all, if he used it, there might be an accident like a Honkai Eruption, right?

So in order to maintain the safety and stability of society, he chose a place that was far away and quiet.

After 15 minutes of running without stopping, he finally found a place where the ground was flat and quiet, with no crickets, no owls hooting, and so on.

Under the dark night with stars as lights, there was only Kouro, standing alone accompanied by the light of fireflies.

But alas, this beautiful place would soon be destroyed by him.

After admiring this natural beauty for a few minutes, he then quickly used the Divine key.

After that, he took out the core fragment of the Herrscher of the end from his 'Inventory'.

He then looked at the core with a nervous expression, after all the Herrscher core he was going to use was not from just any Herrscher, but from the Herrscher that was said to be the strongest that could easily destroy the world.

"... "

Kouro gulped before finally equipping the core into his chest.

The Herrscher core shone into the night.

"ARGH!!!" Kouro suddenly cried out in pain, his body was filled with purple lines with the Herrscher core as the center, and his originally purple eyes now looked bright orange.

Not only that the aura he released made a supersonic blast that destroyed everything within a radius of hundreds of meters and for a moment behind him was seen the silhouette of a girl with white hair and orange eyes looking at him coldly.

*BOOM!

Birds were seen chirping and flying into the sky out of fear of the aura he was giving off.

Moments later, Kouro lay stiffly on the ground with his face facing the sky, he was breathing heavily.

"...Five... seconds..."

Kouro could only use the power of the core fragment of the Herrscher of the End for five seconds before the key of Blankness forcibly shut down the power due to overload.

Well... It was actually not surprising. Rather, he would have been surprised if this Divine key could withstand the power of the Herrscher of the End core.

After all, there is no way any human could bear this Herrscher's strength.

He himself can't even bear this Herrscher's power at all, if it weren't for [Unknown]'s ability, he would have died and become an undead by now...

But even so... Even if he could only activate that power for five seconds, he finally felt the ability of the Herrscher of the end.

Absolute control over Honkai energy.

That means, Herrscher of the end is theoretically invincible, that's because everything in this world is directly related to Honkai energy.

And not only that, the Herrscher of the end is the Herrscher closest to the Will of Honkai and some even say that the Herrscher of the end is the Will of Honkai itself.

But what made him even more curious now was who was the being that could seal the Herrscher of the end?

It didn't cross Kouro's mind that he himself sealed the Herrscher.

Well... Let's not think about this just yet, he had to leave quickly, after all, the explosion must have attracted the attention of the local Valkyries on duty.

He then quickly ran to his car and left.

Kouro did not realize that his current actions had caused panic in the entire organization responsible for fighting Honkai.

...

At the Schicksal headquarters, a panicked Amber was running down a hallway to the Overseer's office and without knocking went straight in to meet Otto.

Otto was currently reading the report on the Kouro team while drinking wine and then looked at Amber who entered uninvited, he was not angry but just stared with a questioning expression.

"Overseer Otto! Very high Honkai Energy Fluctuations have been detected in Indonesia!"

Seeing Amber's panicked expression, Otto raised his eyebrows, it was because it was very rare for Amber to have such an expression, so he quickly asked, "You calm down first, how high is the fluctuation?"

"Fi-five hundred thousand HW..." Amber said with a stutter, this was the highest Honkai energy fluctuation she had ever seen after the fluctuation in Singapore city a few months ago.

"What?!" Otto raised his voice, he immediately stood up and looked at Amber with a serious expression.

"What about the Honkai eruption? Did that happen?"

500,000 HW was no small amount, so much so that even Otto himself would be wary of

Amber took a deep breath before calming down and then quickly answering his question, "No, Overseer Otto, those Honkai energy fluctuations only occurred for a short while before dissipating and fortunately, there were no casualties."

After saying that, she then opened a virtual screen that detected the honkai energy fluctuations and showed it to Otto.

"It only happened for a short while?" Otto stared at the screen that showed images of the ground being destroyed in a radius of hundreds of meters with a thoughtful expression before turning his head to the side.

He saw Ashborn who was sitting casually on a luxurious sofa.

"Ashborn, do you know anything about this?" Otto asked.

"I don't know." Ashborn replied calmly.

Seeing Ashborn still calm even after hearing Amber's words, made Otto calm down too.

"Hoo... Even you don't know... But why are you still calm?"

Ashborn turned to look at Otto and answered simply, "Isn't it like Amber said? The energy fluctuation only lasted for five seconds and caused no casualties at all."

The point was that Ashborn wanted to say that he didn't care about it as long as it didn't harm anyone else.

Otto narrowed his eyes at Ashborn for a moment before ordering Amber to keep this a secret, he also ordered to tell the staff who knew about this to keep their mouths shut.

Ashborn stared in a certain direction with his purple eyes shining brightly.

...

At the World Serpent headquarters, Mobius stared at her virtual screen in front of her with an interested expression.

"~Hmm... Five hundred thousand... I wonder what this Honkai is?"

Mobius put on a crooked smile before then looking at the nearby Gray Serpent.

"Gray Serpent, I want you to investigate this..."

"Understood, Sire. " Gray Serpent bowed his head respectfully before walking backwards and leaving.

Mobius then glanced at her virtual screen which showed the Honkai energy fluctuation place, "Now I remember... That place is where Vill-V lived... I wonder what invention she made in such a place."

...

At the Anti-Entropy headquarters, we see Tesla drinking coffee in a room with Einstein and Welt before suddenly spitting coffee out of her mouth after seeing a virtual screen that suddenly appeared in front of her eyes.

"What the hell!?"

She did not care about Einstein in front of her who was hit by the sprout, she was currently staring at the screen in front of her with a surprised expression.

"Fi-five hundred thousand!? What kind of Honkai has such a high energy concentration!?"

Einstein who was wiping her face using a handkerchief then looked at the virtual screen as well, her expression looking surprised but not as big as Tesla's.

Welt was staring in a certain direction with a very serious expression.

Although it was only for a moment, he could feel the emission of extremely high energy from somewhere, the energy felt so terrifying that it even gave him goosebumps even though he only felt it from afar.

Oh, by the way for your information Welt had retired as a teacher at St. Freya's academy, he retired a few months ago when Kouro was still unconscious.

Having sensed that energy, he could now feel the urgency of the situation and as the leader of Anti-Entropy, he had to make a decision immediately.

"Ein, I'm ready for the experiment." he said looking at Einstein with serious eyes.

...

Sakura and Higokumaru who were currently in the city of Singapore with their hands both full of a pile of fried tofu.

Higokumaru who was eating fried tofu ravenously suddenly raised her head with a serious expression.

"This Honkai energy... Herrscher of the End? No, how could she still be alive? It must my imagination."

...

And the person who caused all of this is currently eating 'Gado-Gado at a stall while thinking seriously about whether or not to stir the 'chicken porridge'.

The next day, in the morning.

Ana, Lin, and Ragna had recovered although not completely.

They didn't linger at the hospital and immediately went to see Kouro and packed up their things before saying goodbye to Maya, Nina, and Nana.

Since Ragna hadn't fully recovered, Kouro ended up piloting the Helios-like airplane, and it would definitely be an unforgettable experience for them.

45 minutes later.

Kouro's plane was landing on the runway of Schicksal headquarters.

Kouro got out of the plane with a bright smile, this was his first experience in flying a plane and it could be said that it was quite fun.

He saw Otto and Amber already welcoming him at the front.

But it was different with Ragna, Lin, and Ana who were passengers.

The three of them were seen getting out of the plane with pale expressions, even Lin was touching the floor with a happy expression even though her eyes looked blank.

"Land... Ah... Land, I finally understand why humans have two legs and no wings..." Lin muttered incoherently.

It seemed that because of Kouro, she had developed some sort of phobia.

(E/D: She got Vietnam War flashbacks. Actually, everyone is getting Vietnam War flashbacks. I want one gif for each character with their names on top. Can I get that, please*Loli noises*)

"I congratulate you on the success of your first mission, you must be feeling tired, right? Now rest well." Otto said before looking at Lin who was touching the floor with such an expression.

"By the way what happened to her?"

"No, nothing, she's just a little tired." Ragna said, before carrying Lin.

"Okay... Then goodbye, I hope you can rest comfortably."

Otto then left with Amber.

It seemed like they really cared about Kouro even to greet him directly like this.

Kouro stared at the backs of the two of them before turning to look at Ragna and the others, "Do you guys need help?"

"No need."

They were now really tired and wanted to get away from Kouro.

"Alright, see you later."

Kouro went to distribute some souvenirs to Susannah, Alvitr, Durandal, Rita, and Nagamitsu, and then after that, he went to his room.

Inside the room, he took out one of the blueprints he had gotten from his 'Inventory'.

The blueprint was 'See-through glasses'.

Kouro stared at the blueprint for a moment to understand its concepts and principles before creating it using the authority of [Death and life].

Staring at the glasses that were no different from ordinary glasses, he with an unsure expression then put them on.

"Woah..."

After putting on the glasses, Kouro could see things behind the wall clearly as if he had his eyes pierced through the wall.

He looked around before his expression suddenly turned red and quickly took off the glasses.

He saw Susannah who was bathing completely naked.

Staring at the 'See-through glasses' in his hand Kouro muttered, "These glasses are dangerous..."

(E/D: Don't know man, I would be slamming my already empty Wallet-chan on the desk for that.)

After saying that he put the glasses back on and stared at the wall where he saw Susannah bathing with a serious expression.

"This is an experiment... Yes. This is an experiment..." If only he wasn't having a nosebleed, then his words would have been convincing.

The next day Kouro did not dare to look directly at Susannah's face.
