Collapse, Traveling from a Moonlit Oath

After speaking with Rias, without waiting for her response, Moonlit grabbed the now cold corpse of Raynare beside her, transformed into a swarm of bats, and quickly disappeared.

Only Rias and the still unconscious Issei Hyoudou remained.

Since Issei no longer possessed a Divine Artifact, Rias lost interest. Furthermore, he wasn't dead, just teleported to a safe location.

When he wakes up, he'll probably go back!

"The real challenge begins now!"

"Welsh Dragon! Dragon Emperor!"

To control the Sacred Gear "Crimson Dragon Emperor's Cage," one must face one of the only two Heavenly Dragons left in this era: the soul of the Red Dragon Emperor.

The Red Dragon Emperor, true name: Vritra!

At his peak, he was among the world's top ten Transcenders, a powerful being second only to Quasi-Dragon Gods.

Even facing just his soul would be no simple task.

However, this was not enough to make Moonlit fear.

If it were the boy from her past life, she might not have been able to. She wouldn't deny that. But now, she was her Moonlit Wife, Moonlit Oath - Giving Love to the Heart!

"Come on, Vritra."

Taking out the newly acquired Sacred Gear, Miss Moonlit transferred it into her own body. The next moment, as Moonlit's spirit touched the Divine Artifact, the girl felt like the entire world had changed!

She found herself in a world of raging flames, a complete fiery realm!

And within this fiery world, an unimaginably colossal Heavenly Dragon appeared before her eyes. This was none other than the Dragon Emperor, the Red Dragon Emperor Vritra!!!

The massive Heavenly Dragon suddenly raised its head, opening its indescribably terrifying dragon eyes.

It stared directly at the Vampire girl before it.

As if assessing whether she possessed the qualifications to be its host.

"This is truly interesting!!"

Vritra suddenly spoke, seemingly very interested in Moonlit, at least not showing any signs of rejection.

"A strange power. I didn't expect the new host to be a vampire. No, not a vampire, but a new, unknown existence."

"You must be a being from another world!"

"That terrifying, immense power... even 777 doesn't possess it."

Vritra's voice boomed, causing the entire mental world of flames to tremble. The invisible pressure... even Angels and Demons couldn't withstand it.

After all, unlike in the original story where the "Crimson Dragon Emperor's Cage" belonged to Issei Hyoudou from the start, his attitude was quite friendly. But now that it had been snatched away, everything was completely different.

Looking at the girl who was about to become his new master, Vritra had never encountered anything like this in all his years.

The being before him resembled a vampire, yet was entirely different. It was a creature even he had never seen, not belonging to this world at all.

"It's nice to meet you, Vritra."

"You are correct. I am not a being from this world."

The girl did not deny it. Beings of this caliber could naturally discern her uniqueness.

"Hahahaha, to be able to bypass that one... the being behind you is truly powerful! I'm starting to anticipate how terrifying you will become in the future."

It's important to know that Earth and its parallel worlds and dimensions are protected by a supreme being, known as Great Red, or 999.

Earth and its parallel worlds and dimensions are collectively called DxD, and the consciousness of DxD is Great Red, also known as the True Red Dragon God Emperor.

Excluding parallel timelines and dimensions, any being from another world wanting to enter the DxD world must first face this supreme being.

Otherwise, entry is impossible!

This is why Vritra was so surprised to discover that Moonlit was a being from a completely different world, not from a parallel world or dimension.

"..."

Moonlit understood what Vritra was referring to.

Great Red was, in essence, the guardian deity of Earth's entire multi-dimensional world. She selflessly chose to reside in the rifts of spacetime, forever imprisoned there.

Meanwhile, the Infinite Dragon God mistakenly believed that Great Red occupied the dimensional rifts and constantly clamored to defeat her so it could go back to sleep.

There were also some Transcenders who felt that the DxD world had become uninteresting and were always thinking of killing Great Red to explore other worlds.

Little did they know, the horrors of other worlds far exceeded everyone's imagination.

"Based on what you're saying, Vritra, you don't seem to reject becoming my power?"

The matter of Great Red was too distant; she wouldn't consider it until she reached SSS-rank. Thinking about Vritra's words, the girl realized... it seemed to have directly accepted her?

This was something Moonlit had never expected. She thought she would have to prove her strength to it.

"Indeed! After all, you are already my partner. Is there any point in me refusing? Moreover, I have high hopes for you."

Ddraig nodded. Not only did it not reject the idea, it actually looked forward to the girl's future experiences. If possible, seeing the scenery of another world would be even better.

When Issei Hyoudou had died before, Ddraig had only just woken up. However, before it could react, it was stripped from the original host Issei Hyoudou's spirit by an unknown, terrifying power (the System).

Facing that terrifying power, it hadn't seen anything like it, not even from God of the Bible.

Although it didn't know the relationship between the girl and that power, it had reason to believe that Moonlit would be no worse than any previous host of the Red Dragon Emperor.

"That would be for the best!"

"Don't worry, Ddraig, I'll prove to you what the true strongest Red Dragon Emperor is. I will pave the path that all previous Red Dragon Emperors failed to complete!"

Since Ddraig had no objections, Moonlit was naturally happy to have one less problem.

"Wait a moment, partner. Are you also going to choose that path?"

Ddraig, who hadn't reacted much before, immediately changed its expression upon hearing the girl's words.

It was very confused about where the girl learned this information. Shouldn't this only be known to previous Red Dragon Emperors and a select few?

"I have to remind you, that path is a curse that all previous generations have been unable to overcome. Even though I don't want to admit it, none of the previous hosts who reached that point survived. It's the nightmare of all previous generations."

Where was the end of Divine Artifacts?

Perhaps many would think that reaching Balance Breaker was the limit of a Divine Artifact. But in reality, activating Balance Breaker was only the first step.

Further up, one would tread the path called Tyranny...

However, compared to other Sacred Gears, the path of Tyranny for the "Crimson Dragon Emperor's Cage" was a nightmare for all previous generations; it was an unbreakable curse.

In the end, no matter how talented a Red Dragon Emperor was, once they reached that point, they would begin to head towards destruction.

Perhaps it was because the name "Red Dragon Emperor" offended Great Red, the "True Red Dragon God Emperor," or perhaps it was because the incantation of the Tyrant Dragon was too arrogant, disregarding even the Two Heavenly Dragons, thus incurring a curse.

Or perhaps it was none of those...

In any case, all previous Red Dragon Emperors had fallen at this step, either losing their minds to Tyranny or succumbing to despair and confusion.

Moonlit had also pondered this issue before.

The path of Tyranny was about moving forward relentlessly, being supreme and unrivaled.

And the Tyranny of the "Crimson Dragon Emperor's Cage" practically told them to step on Great Red and punch the Infinite Dragon God.

Even Ddraig itself was like an ant before the latter two. How could the previous hosts of the Red Dragon Emperor not despair?

"Previous generations are previous generations. They are not me!"

Hearing Ddraig's reminder, the girl remained full of confidence.

This was because she truly had the capital to say such things. Even if the path of Tyranny were to be followed to its end, it would be no problem!

She even dared to make the Two Heavenly Dragons cry...

After finishing her conversation with Ddraig, Moonlit directly withdrew from the mental world.

Having successfully mastered a new Sacred Gear, Miss Moonlit couldn't wait to adapt to it and feel the power of the Red Dragon Emperor.

The basic ability of the Sacred Gear "Crimson Dragon Emperor's Cage" was mainly reflected in "Boost."

It could double the holder's power every 10 seconds. Although it was only temporary, it could allow a weak person to surpass the power of a Demon King or a God.

Of course, there were certain limitations. The number of uses would be limited by the holder's physical body, and the power could not be infinitely increased. During the process, they could not be attacked, and could only escape. Otherwise, the power would disappear all at once.

As for the other Sacred Gear, the White Dragon Emperor's Light Wings, it was the opposite. Its basic ability was to "halve" the opponent's power, also once every 10 seconds, and then add the halved power of the opponent to itself.

It was also a cheating ability...

Of course, besides "Boost," the Red Dragon Sacred Gear also possessed basic powers such as Penetrate, Transfer, and Blazing Fire, which combined to make it incredibly powerful.

The White Dragon Emperor and the Red Dragon Emperor were similar, their powers were alike, only their attributes and methods differed.

As the last two Heavenly Dragons, the Red Dragon Emperor Ddraig and the White Dragon Emperor Albion had extremely poor relations with each other.

In the past, when the three factions of Gods, Devils, and Fallen Angels were engaged in a great war, the Two Heavenly Dragons appeared from who knows where and, in their own way, started fighting on the battlefield, completely disregarding the presence of the three factions and making the battlefield a mess.

Finally, the three factions, unable to bear it any longer, temporarily abandoned their war and unanimously decided to kill these two troublesome Heavenly Dragons first!

The result was that the Red Dragon Emperor's soul was sealed by God into the Divine Artifact "Crimson Dragon Emperor's Cage," and the White Dragon Emperor's soul was sealed by God into the Divine Artifact "White Dragon Emperor's Light Wings."

However, even though the souls of the Two Heavenly Dragons were sealed within the Divine Artifacts, they continued to fight. Therefore, the holders of the "Crimson Dragon Emperor's Cage" and the holders of the "White Dragon Emperor's Light Wings" always engaged in battles.

And the decisive battles between the two basically depended on who could first learn the Tyrant Dragon state.

"Here it is!"

Qian Xun E1②81h1③9

In a suitable location, Miss Moonlit set up an isolating barrier. Although this kind of barrier could not completely isolate powerful forces, it was fine under normal circumstances.

"Boosted Gear!"

The girl raised her arm, attempting to use the Red Dragon's power.

The next second, Ddraig's built-in sound effect for the Divine Artifact rang out, and a pair of crimson gauntlets appeared on the girl's left hand.

The gauntlets were very cool, but they looked a little strange on Miss Moonlit, but it wasn't a big problem.

"Boost!"

Using the power of Boost, the next second... Miss Moonlit's eyes changed slightly. Her power had just doubled? Although her body felt a bit more pressure.

Miss Moonlit's strength far surpassed Issei Hyoudou's. He would need to Boost countless times to reach Miss Moonlit's current level.

The stronger one became, the more the pressure from Boosting was comparable to the burden on the body.

"Boost!"

"Boost!"

"Boost!"

She didn't stop. Every 10 seconds, the young girl activated the power of Boost again, and Miss Moonlit's physical strength began to continuously double.

Her aura became more and more terrifying, approaching Quasi-Demon King, Demon King...

As she rapidly grew stronger, the burden on her body also increased step by step. If she could withstand it, it wouldn't be impossible to kill the Two Heavenly Dragons with a single punch.

Of course, at this level of burden, her body would have long since collapsed!

While feeling the immense power, Miss Moonlit suddenly had an idea. If she had enough Servants, and could find a way to share the burden among everyone, could her power truly increase without limit?

Destroying the world with a single punch might not even be a dream?

However, she didn't know how many Servants would be needed for that...

And there were too many problems with implementing it.

"Balance!"

"Breaker!"

Soon, the Boosting reached a limit. Feeling the young girl release her boundless thoughts at this moment, it was almost instantaneous... the crimson gauntlet rapidly extended and spread, quickly covering her entire body.

Then, with a whoosh, a pair of crimson dragon wings unfurled on her back.

"Boosted Gear Scale Mail!"

A terrifying crimson beam of light shot straight into the sky from her location. The barrier that had isolated them instantly shattered, unable to conceal this immense power.
