Overlord.

When Mare, standing below the throne, saw Fu Gui transformed into a mindless ape, he let out a tiny whimper.

"W-woo... Lord Ainz... I, I think I'm starting to say 'banana' too..." Mare's heterochromatic eyes welled up with tears, and he clutched the giant staff in his arms tightly, his voice clearly tearful. "W-will I turn into one of those apes too...?"

"There is no need to worry, Mare." Albedo, standing behind Ainz, stepped forward, smiling elegantly. "That is merely transformation magic. Even if you were to turn into an ape, we could reverse it for you without the need for the Supreme Being's intervention."

"Hmm..."

However, Cocytus, with his four arms crossed over his chest, uttered in a deep voice, "But, Albedo, the word 'banana' is unconsciously mixed into all of our speech... Can this phenomenon be dispelled with magic?"

"No, I have already tried." Albedo said calmly, then raised her right hand, and a emerald green light once again appeared around her body—the activation of a magic to remove abnormal statuses. But she immediately frowned and shook her head: "...Unable to identify. This condition of speaking with 'banana' does not belong to any mental magic or curse known to us."

"Enough, Albedo."

Ainz, seated on the throne, struck the ground heavily with the scepter in his hand. His majestic voice instantly silenced Guardians below, and they all lowered their heads.

"Albedo, when facing unknown interference and influence, with insufficient information, any underestimation or arrogance is foolish."

Ainz adopted a more serious tone: "This invisible force that affects us is not of the same origin as magic, and the solution will also be different. Just as different locks require different keys, you cannot expect the key in your hand to unlock the methods of Celestial Screen, even if their superficial effects appear similar."

"Y-yes... Lord Ainz."

Albedo bowed her head in shame, her fingers constantly tugging at the hem of her gown.

Ainz had no intention of continuing to scold her, instead turning his gaze to the other Guardians below the throne.

"Aura—"

"Here!" The dark elf, dressed as a boy, immediately straightened his body.

"Immediately raise the barrier level of all forests surrounding Nazarick to the highest. Additionally, investigate whether any of your subordinate monsters have exhibited the 'banana' phenomenon. Furthermore, if any monsters transform into apes, report it immediately."

"Understood!"

"Demiurge—"

"Your subordinate is here." The bespectacled demon respectfully raised his head.

"You are to proceed to the Holy Kingdom and rendezvous with Sebas, gather intelligence, and see if there are any precedents of humans transforming into apes among those people. Furthermore, if you encounter any problems along the way, report them to me immediately."

"Understood, Lord Ainz."

""Miss Rappa, can we now discuss the reason for the Galaxy Ranger's visit to Penacony?""

""Has the Flying Dragon Ninja already noticed something?""

""Dan Heng nodded: "Although I had suspicions before, only after seeing this scene can I be certain. The mortal enemy of the Galaxy Ranger, the terrifying scientist who transforms humans into apes, the Evil Ninja Ape you spoke of... Is he perhaps the Dr. Primitive?"""

""Precisely." Rappa's gaze deepened, and her tone became serious: "The Evil Ninja Ape... is the Evil Ninja Ape!"""

""So is he or isn't he?!""

""Xing rubbed her forehead, feeling like Rappa had said nothing at all.""

""The Dr. Primitive... Genius Society #64. No one knows his true name, but his crimes are known throughout the universe. The most horrifying of these is the 【Ancestral Reversion Experiment】," Dan Heng added. "Dozens of worlds caught in its wake, most of which were thriving interstellar civilizations before his arrival. After he left, those planets were left with only regressed intelligence."""

""Synthetics reverted to machines, Zazka reverted to birds, and the most common human civilizations, without exception, fell into the same tragic state: billions of apes wandering among the ruins of what were once called 【homelands】."""

""If this is true, we must notify the Astral Express and the Family as soon as possible. This is not a crisis we can handle. An Emanator of Erudition who stops at nothing... One misstep, and the consequences are unimaginable."""

"Wait, wait, wait! The Genius Society again?"

Mista's eyes widened, a look of disbelief on his face: "No way? Is this Genius Society really so full of talent? Wasn't the mess Rupert caused big enough already? Now here's another Dr. Primitive. What exactly is in the heads of these geniuses? Unchanneled destructive urges?"

It felt like if Rupert had been born a little later, he could have easily applied to be an Emanator of Destruction; being an Emanator of Erudition was truly beneath him.

"Emanator... Mr. Dan Heng mentioned an 'Emanator of Erudition'." Giorno slowly began, "Currently, the only known Emanator of Erudition is Madam Herta, isn't she? Another Emanator-level existence means that the power the Dr. Primitive can wield is on the same level as Madam Herta's... He could probably annihilate countless planets with a snap of his fingers."

Fugo, frowning, added: "Moreover, this is by no means simple destruction. An Emanator-level existence's actions must have a vast purpose behind them, consistent with their logic. What we see as 'ancestral reversion' might just be the most impactful, yet most superficial, part of his blueprint."

"So what kind of experimental results does this guy ultimately want?"

Mista scratched his hat, somewhat agitated: "Turn everyone back into apes, and then what? Establish an ape kingdom? What good would that do him? Power? Knowledge? He's already an Emanator; he shouldn't lack either, should he? Even if he wants to pursue knowledge, he should pursue it from Nous. What's the point of harming ordinary people?"

"Perhaps... truth?" Giorno smiled bitterly, "I'm afraid for scientists like him, who stop at nothing, nothing is more important than truth."

""A hundred percent accurate analysis. But in my humble opinion, now is not the time to seek aid from the Harmony Shogunate.""

""Rappa said seriously: "The Galaxy Ninpo Scrolls say: Cast a net to catch fish, and both fish and net will be destroyed. The Evil Ninja Ape has not yet appeared, and both enemy and ally are in the dark, so it is not advisable to beat the bush and startle the monkeys."""

""I have already entrusted His Highness Silver Spear Shura to delve deep into the forbidden zone to investigate the situation. Please rest assured, His Highness Silver Spear Shura is a Great Ninja Hero capable of defeating a thousand, and he will surely complete the mission. As for us... what is more important now are the lives of the ninja disciples in Origami Village. They are powerless to fight apes, and if we, as ninja heroes, do not save those before us, how can we save the world?"""

""Dan Heng nodded thoughtfully: "...Indeed, we cannot ignore the safety of the students."""
