With the foundation of Void City secured, Ari dispatches her first batch of basic invitation cards into the infinite void, drawing a bizarre assortment of dimensional travelers into her pristine sanctuary. The arrival of Sheldon Cooper, Naruto Uzumaki, Harry Potter, Sakamoto, and Cinderella marks the first true collision of realities under the watchful eyes of her newly trained staff. When these disparate souls enter the Resource Exchange Center, they are introduced to the raw economic reality of the cosmos through the system's valuation crystal. The results trigger immediate, hilarious reversals of status that leave the arrogant utterly humbled. Sheldon, a self-proclaimed genius with multiple doctorates, is left nursing a bruised ego when the crystal values his entire intellectual output at a meager two thousand points, while the orphaned and neglected Harry Potter discovers his latent wizard bloodline is worth ten thousand. The true shockwave occurs when six-year-old Naruto Uzumaki steps onto the platform, causing the crystal to surge as it calculates his latent chakra, Uzumaki heritage, and a faint Otsutsuki bloodline to a staggering total of fifty thousand points. Even the ancient nine-tailed fox sealed within him is left roaring in impotent fury as the system lists him as a consumable resource worth five thousand points per unit. This massive influx of wealth completely upends the local economy, allowing the children to purchase spellbooks and chakra refinement manuals that instantly integrate into their souls, transforming them from vulnerable outcasts into formidable prodigies. As the guests settle into a grand celebratory feast prepared by Tsukasa, they realize that Void City offers them a sanctuary of warmth and dignity they have never known in their own realities. But this peaceful paradise is merely the calm before the storm, as Ari suddenly prepares to expand the city's boundaries, unleashing a wave of intermediate invitations that will draw the most powerful and chaotic entities of the multiverse directly to her doorstep, forever altering the balance of power.

The stakes of the multiverse escalate dramatically when Nico Robin posts an urgent mission to prevent the public execution of Portgas D. Ace, triggering an immediate mobilization of Void City's heaviest hitters. Ari approves the high-risk deployment, sending Gojo Satoru, Toriko, and the newly arrived Rimuru Tempest directly into the raging fires of Marineford. As Admiral Akainu's molten fist drives forward to pierce Ace's chest, Gojo materializes from a column of golden light, activating his Unlimited Void domain to freeze the entire battlefield in a single suspended second before casually plucking both Ace and Luffy from the jaws of death. The battle transforms into an absolute showcase of overwhelming power as Toriko clashes head-on with Vice Admiral Garp's Fist of Love and sends Sengoku's golden Buddha form crashing through buildings. High above the chaos, Ari lounges on a floating observation deck, enjoying snacks and tea while her employees effortlessly dismantle the World Government's finest. The climax reaches a spectacular peak when Ari hurls the squishy, blue-haired Rimuru directly at Akainu, resulting in a swift, humiliating defeat as Rimuru absorbs the Admiral's magma and traps him in an inescapable ring of Black Flame. To ensure the defeat is absolute, Ari restores the live broadcast feed to the entire world, allowing Sheldon Cooper to deliver a devastating, fact-based roast that exposes the systemic atrocities, slavery, and hypocrisy of the Celestial Dragons to a stunned global audience. Gojo seals the victory by erasing an entire fleet of arriving CP0 ships with a single, magnificent Hollow Purple, leaving the world's old order shattered and trembling. This unprecedented intervention completely rewrites the destiny of the pirate world, proving that Void City's authority reigns supreme over any mortal empire. But as the dust settles over the ruined plaza, Ari realizes that the true mastermind behind the world's suffering still sits on the Empty Throne of Marijoa, waiting for a challenger brave enough to breach the heavens.

Determined to finish what they started, Ari teleports her entire coalition directly onto the sacred soil of Marijoa, launching a full-scale assault on the highest authority of the world. While Gojo, Toriko, and Sunny systematically dismantle the monstrous transformed shapes of the Five Elders, and Shanks fights a mysterious mirror image of himself named Shamrock, Rimuru Tempest marches alone into the Empty Throne room to face the ancient ruler, Imu. The confrontation escalates into a battle of cosmic proportions as Imu transforms into a colossal, black-scaled beast, only to be met by Rimuru's own towering True Dragon form, which radiates a terrifying pressure that shatters the palace's marble foundations. Rimuru dominates the exchange with effortless grace, catching Imu's strikes bare-handed and repeatedly slamming the ancient monarch into the ground like a rag doll. When a desperate Imu attempts to use mind and body possession to seize control of the slime, the Great Sage easily rejects the intrusion, allowing Rimuru to activate his ultimate skill, Beelzebu, and consume the ancient ruler whole, erasing eight centuries of tyranny in a single, silent moment. Following the victory, Ari oversees the distribution of the Celestial Dragons' hoarded wealth to the Revolutionary Army and personally frees the slaves, using her power to erase the hated brand of the Nine Oxen from Boa Hancock's skin. This act of profound kindness completely wins the heart of the Pirate Empress, who vows her eternal loyalty to the lazy City Lord. Ari then issues a global ultimatum, demanding a world conference to build a new era of self-governance while threatening to return and flatten any nation that falls back into tyranny. The fall of Marijoa establishes Void City as the ultimate arbiter of justice across the multiverse, but the peace is short-lived as the system's mission board lights up with an urgent plea from a world plagued by ancient, flesh-eating demons.

The narrative reaches a breathtaking emotional climax when Levi Ackerman confesses the impending doom of his world's forced military cull, prompting a deeply moved Ari to initiate a full-scale time reversal that resets the tragedy before it can begin. Riding onto the battlefield atop the golden dragon Ryuveel, Ari and her coalition organize the refugees while her young disciples, Naruto, Harry, Luke, Sasuke, and Killua, put their rigorous training to the test, easily reaping the mindless Titans like wheat under the protection of her absolute barriers. This successful field training leads directly to a massive military coup that overthrows the corrupt royal family of Paradis, placing the young Historia Reiss on the throne and securing another world's future. Upon returning to Void City with a staggering fortune of forty-seven million points, Ari commissions a grand, three-story auction house with a transparent dome looking out into the starry cosmos. The event draws delegations from every corner of the multiverse, eager to bid on legendary artifacts like the wishing lamp, the Philosopher's Stone, and the highly anticipated five unconditional resurrection slots. The bidding war ignites deep personal rivalries, culminating in Tsunade securing a slot to bring back her beloved brother Nawaki, and Naruto finally reuniting with his resurrected parents, Minato and Kushina, who immediately demand a fierce accounting from the village leadership that neglected their son. As the auction house dissolves into a joyous celebration filled with food, music, and laughter, Ari quietly initiates a massive infrastructure upgrade that will transform Void City into a floating metropolis. This grand expansion secures her position as the ultimate landlord of the multiverse, but the peace is suddenly threatened as the system chimes with a warning of a massive dimensional fissure ripping open at the edge of her territory, preparing to unleash an ancient, forgotten god of the void.
