The time had come. Akiyama Ren—no, Lord Ren-sama, as some had begun calling him—stood still as a divine glow radiated from his body. Following King of Wisdom's guidance, he began fusing the natural talent "Elemental Control" with several key Authorities: 'Gale and Angry Waves,' 'Lord of the Sky,' and the Goat Incarnation from the Eastern God of War.
The result? A new, terrifying Authority—Element Master!
"Yatta!" Ren whispered to himself as a surge of elemental mana circled him.
This Authority allowed him to wield dominion over all elemental forces—not just basic ones like fire, wind, water, and earth, but every element imaginable, even those not on the periodic table. From hydrogen to mythical star-forged quintessence—if it existed, he could manipulate it.
But that wasn't all. Element Master granted him control over weather phenomena like typhoons and thunderstorms, the seasons, and even the twenty-four solar terms used in East Asian cosmology.
With a smirk, Ren flicked his fingers, and dark clouds formed outside Lucrezia-san's mansion in Sardinia, only to be swept away in the next second.
"Ara ara… such power," he said, his voice dripping with anime-style flair.
Following that, under King of Wisdom's suggestion, Ren focused on something even grander.
Using two foundational Authorities—Demon Path Dominator and Chanting Spellbook—Ren fused them with 'Holy Disorder,' 'Steel Rampage,' 'Blood Holy Communion,' and four incredibly potent talent abilities: All-Purpose Transformation, All-Purpose Perception, Matter Conversion, and Matter Creation.
The result?
The Supreme Authority—King of Abundance!
"Unbelievable…" Ren gasped.
Yes, it bore the same name and function as one of Rimuru Tempest's ultimate skills in the late stages of Tensei Shitara Slime Datta Ken—and rightfully so!
This Authority granted four main abilities:
Ability Creation
Ability Copying
Ability Granting
Ability Storage
With this, Ren no longer needed to devour to acquire powers. Now, all he had to do was imagine a skill—magic, technique, Authority, Jujutsu, Onmyōdō, even Noble Phantasms—and if its scope didn't exceed his power, he could craft it into existence!
"Time to test it out~" Ren-san chuckled.
He held out his right hand. Wind coalesced instantly, swirling into a high-speed vortex of raw chakra.
"Fūton: Rasen Shuriken!!"
BOOM! A wind shuriken spun violently, tearing space before dissipating.
Then came the eyes—oh, the eyes!
Using King of Abundance's creation function, Ren cycled through every anime eye technique he could recall from his past life. First came the Mystic Eyes of Death Perception, his irises turning eerie blue with crimson rings.
Then—bam!
Sharingan! Rinnegan! Byakugan! Tenseigan! Jōgan! Nine-Tomoe Rinnegan! Geass! Eye of the Fairy King! Eye of Ruin! Petrification Eye! Annihilation Eye! Even obscure ones like Twisted Demonic Eye and Eye of Contract made an appearance!
He fused all of them into his Divine Eyes, birthing a transcendent ocular ability: God-Demon Eye!
One glance could manipulate the cycle of creation and destruction, of life and death.
His left eye gleamed golden—God. His right, a searing crimson—Demon.
Truly a sight worthy of anime legend!
But Ren wasn't done being chuuni yet.
With a wicked smile, he created the power of the Sun, drawing inspiration from Escanor's Sunshine and Karna's Sun Authority from the Type-Moon Universe. Combining these with the 'Judge of Karmic Fire' Authority and the White Horse Incarnation from Eastern God of War, he gave birth to the Solar Authority.
Yet what followed was something unexpected.
As the Solar Authority solidified, a notification from the King of Wisdom echoed in his mind:
[Warning! Breaking-the-Mold Authority Being Born!]
And thus, the incomplete but incomprehensibly powerful Original Star was formed.
"Uso da rō…" Ren muttered, eyes wide.
Yes. Original Star—one of the two-digit Divine Spirit Ranks from the Mondaiji-tachi ga Isekai kara Kuru Sō Desu yo? universe (a.k.a. Hakoniwa).
Though incomplete, at just 1% of its full potential, it still broke the system of nearly any universe it entered. Such a being couldn't even be classified using conventional power tiers!
Ren tried to forge all 24 Solar Authorities from the Little Garden (Hakoniwa), hoping to complete Original Star.
But—baka!—the system rejected the attempt.
"The rank is too high... I can't handle that power yet," he muttered, sweat trickling down his cheek.
If he returned to the No Game No Life world, perhaps he could cheat it using his status as the omniscient and omnipotent Only God. But even then, the burden of a completed Original Star might shatter his very existence.
So he chose patience.
Instead, he fused his three primary god spirits—Evil God, Battle God, and Dragon God—with the 1% Original Star core, upgrading it to 5% completion!
Even this fragmentary version granted an unfathomable increase in conceptual power.
Satisfied, Ren finally exhaled and said, "System, create a status screen. Let's see where we stand now."

"Fuhahaha! I'm built different!" Ren-sama laughed with full anime-villain energy.
Akiyama Ren's strength had skyrocketed once again, leaping from the level of a mere Planet Buster to that of a Galaxy-class powerhouse. Yet, deep inside, Ren understood clearly—his destructive might had already far surpassed the standard Galaxy tier. He was no longer someone who could be measured by ordinary benchmarks.
Even after fusing together many Authorities, nine still remained. Out of the Eastern God of War's ten incarnations, only Strong Wind, Bull, Camel, and Phoenix lingered within him, unintegrated. Then there were the three unique Authorities—Sixth Heaven Demon King, Servant Cage of Death, and Return to the Ancient World. Ren deliberately left these untouched, fascinated by their peculiar properties. His instincts told him they could serve as the foundation for something far more special.
Take, for instance, the Authority known as Return to the Ancient World. When unleashed, it could force the surrounding environment into a regression, dragging civilization back to the European Middle Ages. Any form of technology that did not exist in that age would instantly fail.
To modern humans, that was terrifying enough. But to Ren, who already anticipated future encounters with technologically advanced civilizations beyond the Star Gate, it was a divine trump card. No matter how advanced the enemy might be—spaceships, energy cannons, or mechanical armies—before this Authority, they would be reduced to powerless husks. Against him, they would be forced to fight with nothing but swords, horses, and crude armor.
"How amusing," Ren muttered to himself. "This one's definitely worth keeping."
Overall, the gains from this integration session were phenomenal. Eternal, Original Star, and King of Abundance stood out as the greatest treasures.
Eternal was exactly as its name suggested—immortality in its purest form. With it, Ren's existence transcended life and death. Not even the crushing laws of higher-dimensional worlds could erase him now. Original Star, meanwhile, gave him the perfect foundation to one day rise to the level of a two-digit Cosmic Truth within Hakoniwa's Little Garden. And King of Abundance freed him from the need to devour or steal skills—he could simply create what he desired, as though writing new laws into existence.
"These three… exactly what I needed," Ren whispered, his crimson-gold eyes gleaming. With them, his rate of growth had multiplied several times over. He could already envision it: one day soon, he would stand as a true Plenipotentiary, a being of Cosmic Truth.
While Ren savored his new powers, chaos had erupted across Europe.
It had been less than a day since the fall of Marquis Voban, yet already the news had spread like wildfire through the magic associations. At first, rumors swirled wildly, no one certain who had struck down the ancient Wolf King. But the truth was not hidden for long. The magic societies of Europe had pulled every string available, mobilizing government resources and scanning through satellite footage in a desperate attempt to uncover the killer.
Their efforts paid off.
By sheer coincidence, a satellite operated out of Luxembourg had caught grainy footage of the battle in the Balkan Peninsula. And once the images were compiled and analyzed, everyone who saw them froze in shock.
It was him.
The seventh Godslayer—Akiyama Ren.
The young man who had already slain the King of Swords, Salvatore Doni, had now toppled the legendary Wolf King, Sasha Dejanstahl Voban. In the span of days, two of Europe's most fearsome Demon Lords had fallen to his hand.
"What is his goal…? Does he seek to unify Europe?" whispered magi across the continent. Panic grew quickly. Godslayers were paradoxical existences—feared as Demon Lords, but relied upon as humanity's only defense against Heretic Gods. And now, Europe had none left. Should a divine incarnation descend again, who would protect them?
Fear spread like wildfire.
Meanwhile, far to the south, Erica Blandelli had just finished delivering her report to the Seven Sisters Magic Society. She intended to return to Sardinia, but her path was blocked by her uncle, Paolo Blandelli.
Standing tall and broad-shouldered, Paolo Blandelli was the current commander of the Bronze Black Cross. To many, he was the very image of a knight: his physique rivaled the sculpted perfection of Michelangelo's David, and even at nearly forty, he carried himself with youthful vigor. His chiseled features radiated intelligence and determination, and his reputation stretched across the continent.
Known as the Red Devil, Paolo had once unleashed the Word of Power—Divine Annihilation—reducing the ancient Lancaster Castle to rubble. His greatest feat, however, was protecting Princess Alice herself: only a single day after awakening as a Divine Annihilator, he stood firm against the six Divine Familiars summoned by the dreaded Erinyes, safeguarding the princess as she slumbered.
A man of myth and legend in all but name—Paolo Blandelli was everything a knight could be, short of being a Godslayer.
"Uncle? What's wrong?" Erica asked, brow furrowed at his grave expression.
Paolo's voice was low, heavy with tension. "Just now, I received word… the Wolf King, Marquis Voban, has been killed. And the one who slew him… is the seventh Godslayer."
Erica's eyes widened in shock. "What?!"
Her heart skipped a beat. She had only just parted ways with Ren, and already he had slain another Godslayer? What was he planning? To hunt them all down? To stand alone at the summit of their kind?
The thought unsettled her deeply. Yes, Godslayers were Demon Lords, dangerous and unpredictable, but humanity needed them. Without them, if a Heretic God appeared, humanity would be utterly defenseless.
Paolo studied his niece carefully. "Rumors are already spreading. They say this Ren seeks to dominate Europe. You've dealt with him directly, Erica. Do you believe this?"
Erica fell silent. Her memories of Ren swirled in her mind. He was sharp-tongued, irreverent, and his aura carried a dangerous, almost evil charm. He rarely considered consequences, and his actions seemed guided by whims that no one else could predict. Yet… when she asked him to acknowledge Salvatore Doni's control over southern Europe, he had agreed without protest. More than that, he had even instructed her to inform the commander of the Seven Sisters Society directly, almost as if he were declaring his own ambitions without concealment.
Her lips pressed into a thin line. He's dangerous… dangerously ambitious.
"Perhaps…" Erica finally nodded. Her crimson eyes, however, carried a trace of unease.
"If that's the case, then tomorrow it cannot just be the Seven Sisters' commander meeting him. The commanders of the Northern European Magic Associations must also attend." Paolo's voice was heavy with caution.
"Then, I won't head to Sardinia just yet. I'll first notify the commanders in Northern Europe." Erica immediately understood her uncle's intent.
"You won't have enough time if you go alone. First stop by the Bronze Black Cross and inform Diana Militou of the situation. Then, travel to Northern Europe with Liliana to notify those old relics," Paolo instructed firmly.
"Yes, I understand!" Erica bowed slightly before turning on her heel, her cloak swirling as she disappeared into the hall.
"I hope this doesn't turn into a calamity…" Paolo muttered as he watched her figure vanish into the night.
....
That same night, in Sardinia.
At Lucretia's residence, Akiyama Ren was savoring a meal prepared by the young sorceress Arianna. To his surprise, the girl had genuine talent in cooking. Earlier that noon, he had casually mentioned that he preferred Chinese cuisine over Japanese. By evening, she had somehow conjured up an entire banquet of Chinese dishes.
The most remarkable part? It was her first time attempting them. While some Chinese and Japanese dishes bore similarities, their preparation methods were vastly different. Yet Ariana had studied them, practiced, and replicated so many in just one afternoon. Ren couldn't help but smirk between mouthfuls—this girl had potential beyond magecraft.
At the table, Lucretia's gaze lingered on him, her lips parting slightly as though she had something to say. Her hesitation was irritating.
"What is it? Just spit it out already," Ren said bluntly, setting his chopsticks down. He disliked two kinds of people more than anything: those who spoke in riddles, and those who had something to say but danced around it with hesitation. Both tested his patience.
Lucretia swallowed, her voice timid. "It's just… the European mage associations are spreading rumors that you killed Marquis Voban." She pulled out her phone, revealing a mage chat group filled with Europe's top sorcerers. The chat was ablaze with messages about Voban's death, accompanied by satellite images as supposed evidence.
She shook her head, conflicted. "I didn't believe it, of course. You've been here the whole time. They're clearly slandering you…"
Ren cast a casual glance at the screen before smirking. "No, they're right. I killed that old wolf."
Lucretia froze. Her eyes widened in disbelief. "Eh? But… but you've been at my house all this time!"
Ren leaned back, amusement flashing in his dark eyes. "Ever heard of Teleportation? Or, to put it more bluntly—space magic."
Lucretia's breath hitched, realization dawning. "Space… magic?"
"That's right. You catch on quickly." Ren snapped his fingers. In the blink of an eye, his seat was empty, and the next instant, he was lounging in the chair right beside her.
Lucretia gasped, her emerald eyes lighting up with wonder. The implications of such magic were enormous. Instant travel across vast distances, freedom from the shackles of mundane transportation—it was a dream for any mage. She wanted it. No—she needed it.
Ren smirked, easily reading her thoughts. "You want to learn it, don't you? That's fine. But nothing comes for free." His gaze swept over her, deliberate and heavy, his smile sharpening like a predator testing its prey. "So… what exactly can you offer in return?"
