After the original Four Great Maou were destroyed, those who had inherited their bloodlines became the ones pushing for total resistance when it came time to select new Maou.
The exhausted Devils, who were already weakened from the war, used the last of their strength to banish the stubborn Old Maou faction to a remote corner of the Underworld.
After that, a new regime was established for the sake of the race's survival. That is the current Four Great Maou.
The woman who had inherited the blood of the Old Leviathan, Catria Leviathan, smiled provocatively.
"Most of the Old Maou faction has already decided to ally with the Khaos Brigade."
"So, it's official—you're declaring war on the New Maou faction. The Devils really don't have it easy, do they?" Azazel chuckled, merely observing from the sidelines.
"Catria-chan… are you saying you're declaring war on us?"
"Serafall, that's exactly what I mean. We also took part in this attack."
"You're going to start another war…? Is the title of Maou really worth throwing the Devils back into a state of utter ruin?" Serafall said bitterly.
"Catria-chan, why?"
Yes—this was a coup. The Old Maou faction launching a rebellion against the current Maou, just like the Reformist faction once did back then.
"Serafall, you should see this meeting in reverse. Precisely because God and the previous Maou are gone, it's time for this world to change. That's our conclusion."
So this coup was launched knowing that God was gone and that the three factions were seeking peace?
"That damn Ophis is already thinking that far ahead? I really didn't expect it," Azazel commented.
Catria merely sighed. "She's just a symbol of power—a rallying point. We'll use her strength to destroy the world once, rebuild it, and then make the new world ours!"
"Gathering rebels from Angels, Fallen Angels, and Devils… so you want to rule your own world, create a brand new Earth. And Ophis, the Ouroboros Dragon, is the one holding it all together," Sirzechs said with rare, mocking derision.
"Catria-chan! Why would you do this?!"
The Maou girl Serafall looked at Catria with regret, but the latter only glared back with resentment.
"Serafall, you stole the title of Leviathan from me and dare to ask why! I am the rightful heir to the Leviathan bloodline! I'm more suited to be Maou!"
"Catria-chan… I… I—"
"Don't worry, Serafall. Today I'll kill you here and reclaim the name of Maou Leviathan. Then Ophis will become the god of the new world. She only needs to be the symbol. The System, the laws, the ideals—we'll rebuild them ourselves. Michael, Azazel, and Lucifer—Sirzechs—you…"
Catria's words were cut off as a wave of biting cold carrying lethal intent fell toward her neck, making the arrogant descendant of the Old Maou involuntarily flinch.
"You damned brat… you dare raise a hand against me?!"
Seeing that the one who struck was an unfamiliar man sitting beside Rias, Catria naturally dismissed him as a junior. And indeed, Yoru was just a soldier.
"I have to ask… where's your dignity as Maou? Letting a has-been, a stray dog, point fingers at you? If the Old Maou lost the war back then, that means they were the losers—existences cast aside by a world that keeps moving forward."
Yoru's voice was calm as he gripped Frostmourne, his half-smiling eyes fixed on Catria.
"If mercy was shown before out of sentiment, then there's no reason to hold back now."
"Yoru, this matter…"
Serafall looked troubled. After all, she had taken what rightfully belonged to the other party and exiled them—it was only natural to feel conflicted.
"What's with this brat? Does he not know the most basic manners? A mere junior dares to interrupt now… killing him wouldn't be a problem, right?"
Catria sneered coldly, her words carrying a hint of cruelty. The next second, she struck at Yoru without hesitation.
An overwhelming surge of demonic power gathered in her palm. Possessing Maou-class strength, the voluptuous woman attacked with killing intent, determined to end him here.
But just as Sirzechs and Serafall's expressions changed and they prepared to intervene, Yoru's counterattack was even faster and more ruthless than they imagined!
The God-killing weapon whose name even they didn't know emitted a chilling aura in Yoru's hand. The blade spun, and with the flat of the sword, he struck the attacking Old Maou descendant across the face faster than she could react.
PAK!
The sharp, crisp sound made everyone's scalp tingle. The pain Catria must have felt was easy to imagine.
The slap-like blow sent her crashing into the wall of the conference room, blasting a huge hole through it before her body continued flying like a broken kite, out of the school building and toward the ground.
"My, my… I may have used a bit too much force there. But to think that a supposed Old Maou Leviathan heir with Maou-level power would be so fragile."
Looking at the gaping hole in the wall, Yoru showed slight surprise, then spoke with an oddly meaningful tone.
In truth, he was genuinely shocked—this so-called Old Maou heir was far too weak, even weaker than Kokabiel.
As the room fell into dead silence from Yoru's sudden action, loud, unrestrained laughter rang out.
"Hahaha! Brat, you couldn't be more right. These Old Maou faction fools are hilarious! With such pitiful strength, they still dare to boast in front of two of the Maou of the Underworld. Sirzechs, Serafall, I may have underestimated you—you're not as decisive as this junior here."
