"DO NOT MESS WITH ME!"

Kuoh Academy has recently been the site of numerous historic moments, with many more to come.

The coming together of three rival factions that have been at odds since their creation.

The identification of the chaos brigade, a terrorist organization comprised of a vast number of extremely powerful and dangerous individuals. The rekindled curiosity about Ophis the infinite dragon's world. Vali Lucifer is a half-demon who is a descendant of the first underworld king and the white dragon. And the pivotal clash between Vali Lucifer and Issei Hyoudou. The red and white dragon emperors, respectively.

Which one of them is now...

"I'M NOT GOING TO LET YOU CHANGE THEM, RIAS'S BOOBS ARE PERFECT!"

Is enraged about tits.

This is the current red dragon emperor Issei Hoyudou, self-proclaimed harem king and breast coinsurer.

"You monster!"

(BOOST!)

"No, you are completely evil!"

(BOOST!)

"I swear I'll never forgive you!"

(BOOOSST!)

As the low-class devil's aura blazed, a dazzling emerald glow filled the entire campus.

"Try laying a hand on Rias Gremory..." The deviant looked at me with strange hatred in his eyes. "I dare you!"

As a reflex, most intelligent beings pause to allow their minds to properly digest unusual events as they occur.

This happens at least a few times during the given entity's life.

Sadly, for Vali.

The white dragon paused to verify his opponent to ensure that he understood everything.

This was his.

"I'm sorry, what?" The individual with white hair had to ask.

"I'll completely destroy you so that you'll never reincarnate again!" Issei pounced on his opponent without even bothering to respond.

In a mad dash, the red dragon emperor strikes the vanishing dragon with a devastating sucker blow.

While still feeling the effects of the blow, the half-demon prince made every effort to gain some distance.

Nothing, however, could have deterred the pervert's rage-induced righteous(?) power-up.

"What happens next? If you had your way, it wouldn't just be Rias, would it?" As he gripped his opponent's shoulder and delivered another vital punch to the stomach, the delusional man yelled.

"For Rias and her mammothmon melons!" The high school student cried.

However, before the victim could respond, he heard something from his opponent's equipment that was thought to be completely implausible in a million years.

(DIVIDE!)

And lost the majority of its ability to respond almost immediately.

The Lucifer descendant was reeling once more when his adversary grabbed his helmet and spoke.

"And this is for Akeno's massive honkers!" The resurrected devil yelled as he slammed it against his own, causing both of them to shatter from the impact, revealing their faces—one clearly perplexed, the other clearly filled with wrath.

"This is for Asia to keep growing!"

The boob aficionado roared and repeatedly kicked his fellow devil.

"For Xenovia's devastating gazongas!"

Then, even the leaders of the three factions looked on in awe as he did something that stunned everyone on the field.

He burst out crying.

"This is also for Keneko! They cannot be divided! Only very lonely nipples would remain!" After striking his opponent once more, they both crash into the ground.

Before the smoke cleared, a man's voice could be heard in the dust.

"Interesting..."

"Extremely fascinating!"

"NO! THIS IS AMAZING!"

"You've been so full of surprises, haven't you?! Issei Hyoudou!"

The white dragon emperor rose from the ground, barely looking hurt despite having taken a beating, and even grinning madly.

"Alright then..."

"You think you can keep up?"

"It's the juggernaut drive." Vali said ominously while owning a psychotic grin.

But surprisingly another came to disagree.

"Forget it Vali right now is not the most ideal scenario."

But the half breed ignores his partner.

"I, who is about to awaken, —"

"I am the Heavenly Dragon who has taken the principles of supremacy from God."

"I envy the infinite and I pursue the dream—"

"Vali, are you telling me to adapt to this situation!?"

Still ignoring his partner Vali continue power growing by the second.

"I shall become the White Dragon of Supremacy—"

"— And I shall take you to the limits of white paradise!"

"Juggernaut Dri-!"

"VALI!"

Because of their extensive experience with the white dragon beside his welder, only Ddraig and Azazel noticed the change in tone.

"Was that?..."

"No way..."

He spoke with a mixture of anxiety and... Fear?

Vali paused and turned to face his gear with a newfound expression on his face as soon as Issei noticed a growing tension.

He had lost his savage grin and replaced it with a shaky one, as if he was struggling to get by in the hole, he had dug for himself while gazing up at the sky.

The white dragon spoke again, but this time in a strangely low voice.

"She's here."

Then, all of a sudden, the sound of jet engines boomed, and the sky turned a familiar shade of blue.

As the barrier crack shattered like glass, an entity descended next to the white dragon emperor.

"What the hell?!" Issei cried out in confusion as the collision caused dust to gather and force him to cover his face.

"Impossible..."

"What is it, Ddragi?" Issei yelled out, slightly alarmed by his partner's tone, but paused to observe the visitor.

When everything had calmed down, a small girl the size of Keneko... No, more like Gasper appeared. But like his female junior, she had piercing gold eyes but with longer pristine white hair that reached her waist and was adorned with black accents.

Her clothing was the focal point of attention. Her gauntlets and torso were covered in armor with rose-like designs that were not so like scale mail that wrapped tightly around her (which was surprisingly ample the pervert thought absent mildly). But it was the overwhelming sense of wrongness that bothered him the most. He appeared to have to do a double take every time he caught sight of her.

However, before anyone could respond, the girl turned to the bearer of divine dividing and spoke three words while giving him a mild glare.

"You left me."

"I-I can expla-"

"Vali told me not to wake you." Vali looked at Albion as if he were a befuddled child who had just been told on, as the dragon soul immediately ratted on him. The unidentified girl simply sighed, shook her head, and motioned for him to stoop lower so they could be face to face, which the young man did warily but sharply. She then without thinking twice about it began pinching his cheek after that.

"Vaaali, I'm sure that I didn't raise you this way." The girl chastised him and didn't seem to be stopping.

"Ow ow ow! Melusine, please stop, your anti-dragon abilities are causing this to really hurt!" Vali begged.

"Hah, that little, adorable child has now grown into a troublemaker. Why can't you be cute like Percival?" The newly identified girl sighed and ignored his desperate pleas.

"And, as I previously stated, don't hold me to expectations for someone I've never met!" Satan's descendant retorted.

"But you're still not out of it! You said, "Today is my day!"" His tormentor scowled and tightened the squeeze, as if there was no tomorrow.

Issei and his companions could only watch as they argued like siblings.

Not just from shock.

But being treated in this manner after witnessing the individual who had just threatened to kill half of those present was perplexing to say the least.

But fortunately (or unfortunately), the Gorgoi leader spoke up."

"Hey, Vali! Is this the imaginary friend with whom you were supposed to stop talking to?" The fallen angel remarked without remorse that even his comrades were looking at him for his lack of tact.

The two both paused and looked at the annoyance with glazed eyes before the shorter one spoke up.

"Can we just murder him right now?" The smaller one, who was pointing at him, made a remark.

"No, you cannot. We've already discussed how his exit would cause too many problems." Vali denied despite the fact that the young man's expression suggested otherwise.

The man's only action during the discussion of his murder was to jokingly place his palm next to his heart and remark, "Ouch! You kids have harmed this old man!" and, in essence, welcomed it

However, their humorous banter was cut short by a deep voice.

"Albion… what... What is that?"

"It's better if you hear it from her yourself" His counterpart responded.

Silence fell as everyone turned to look at the source of this new mood.

"It's rude to talk about someone as if they weren't even present... However, I understand because I am aware of how I appear to you." Despite her words, she appears to be unconcerned that her presence has caused everyone to become tense once more.

Without any fanfare energy around her then erupted to life, engulfing her in power that they had previously experienced.

From the person directly across from her.

Issei's widen as big dinner plates him completely understand the situation.

"Wait, isn't that? That's impos-"

But the girl interrupted Issei before he could say anything else.

"I am the one guarding the horizon, which serves as a portal to a different universe passed down from Britain!"

"The previous dragon had passed away. Its meat had decomposed and turned to mush by the time I awoke inside of it."

"Melusine truth, the last piece to open the threshold, the aircraft that ignited the Fairy Nation from another realm!"

"Albion is my given name. The unknowing, indifferent heartbeat!" She proclaimed proudly.

What runs through their mind was.

"It can't be-"

"Impossible-"

The sacred gear welder next to her, on the other hand, had nearly the same power, aura, and signature as she did.

Nobody could refute it.

Melusine spoke while smugly placing her hands on her hips and grinning wickedly.

"And all I can say is that we're here to take the title of strongest!"

The sole voice that dared to permeate the air was that of a tired teenager eager to finish the day.

"You spent a long time preparing your speech, didn't you?"

She turns to face her benefactor, flashing him the same sly grin he's seen dozens of times.

Above all, one that he adores and wishes to protect.

"Oh, nefariously."
