The Terror Of The Mutant Baboons
On June 23, 1945, during World War II, the United States Army and Marines secured Naha and Kokusai Street, leading directly to the capital's main thoroughfare. The Battle of Okinawa was winding down, with the last remnants of the Japanese Army holding out near the steep, rugged hills of Mount Yonaha.
Eventually, the remaining Japanese soldiers were killed or committed suicide. Few prisoners were taken. A week later, I—Dr. Ashton Crawford, an American biologist—was summoned by the U.S. Army to a remote location within that lofty region. At the time, I was in Australia. Though I had never been to Okinawa, I was familiar with Japan, having collaborated with Japanese scientists a decade earlier on chemical and biological experiments.
Okinawa, part of a chain of 150 islands in the East China Sea between Taiwan and mainland Japan, boasts a tropical climate, broad beaches, and coral reefs. The largest island stretches 70 miles long and 7 miles wide, south of Japan. Upon arriving in Okinawa, I was swiftly escorted to Naha and then to a military compound near Mount Yonaha. I was given little information about the purpose of my summons.
Captain Holden briefed me upon arrival. Apparently, there was classified information regarding unusual and secretive experiments conducted by Japanese scientists during the war. I had been chosen for this critical task due to my extensive experience in biology, my previous collaboration with Japanese scientists, and my fluency in Japanese.
The military compound bore signs of a horrific slaughter; deceased Japanese soldiers were scattered everywhere. It was presumed they had been killed by American troops, though it was unclear if some had committed suicide afterward. I found myself in a dark, disheveled corridor leading to a laboratory, where signs of elaborate experiments suggested a calculated effort to create something abnormal.
The question arose: What abnormality had the Japanese scientists attempted to create that concerned the U.S. Army? The Japanese had urgently sought to develop a secret weapon, but their efforts were interrupted by the arrival of American soldiers, according to documents retrieved from the compound.
After reviewing the information, I made a startling discovery. The Japanese had been conducting disturbing experiments with wild baboons, attempting to create a mutant race. The project was codenamed "Kamikaze," referring to suicidal attacks. I was both stupefied and fascinated by the details within the documents.
Upon deciphering the contents, I immediately reported my findings to Captain Holden. Naturally, he was eager to learn more about the status and effectiveness of the Japanese experiments. I explained that the Japanese had been in the process of creating what appeared to be mutant baboons.
When he asked for clarification, I stated that the baboons were being engineered as malicious assassins. This revelation required confirmation. Fortunately, among the Japanese prisoners taken, two scientists had been involved in this clandestine operation: Kanbun Yabu, an Okinawan, and Tatsuhiro Shimabuku, a Japanese national. I first questioned Dr. Shimabuku, but he remained adamant in his defiance and silence, offering no cooperation.
I then attempted to converse with Dr. Yabu, the native Okinawan, hoping he might be more receptive to our offer of immunity in exchange for compliance. My orders were not only to verify the authenticity of the documents but also to assist in the strict interrogation. I am uncertain what inducement led Dr. Yabu to reveal such private information to the U.S. Army.
All I was told was that he had assented and made an unbelievable disclosure. Dr. Yabu confessed under duress that he had been an accomplice in a horrific experiment with foreseeable consequences. The experiment was more than a mere animalistic conception.
The inconceivable horror I learned was realistic. The question that hastened our intrigue was: What happened to the experiment? Did the scientists succeed in creating a mutant form of a wild baboon? The answer was yes. The experiment had been effectuated with total success.
I inquired about the location of the mutant baboons. Dr. Yabu informed us that they were in tunnels beneath the military compound. He also mentioned nearby forests where the tunnels led. The supposed tunnels were long and narrow in construction.
The notion of savage, mutated baboons heightened my suspicion. After the interrogation, I delved deeper into the documents exposed. I had studied primate biology and was aware that baboons are the largest non-hominoid members of the primate order.
These experimental baboons had formed an uncommon conglomeration of olive baboons, Guinea baboons, yellow baboons, hamadryas baboons, and the largest of them all, the chacma baboons. The thought of chasing these supernatural primates in the harsh landscape of Mount Yonaha or the Yanbaru Forest, with its oppressive humidity, seemed an absurd and unthinkable proposition to Captain Holden.
He was not prepared to waste men chasing presumed baboons. The evolving ordeal of defeating the Japanese and reaching mainland Japan was a pressing issue. The order from Washington was to continue forward, and Captain Holden was commanded to head to the other islands of Ikishima and Tomari to defeat the remaining Japanese troops there.
The entrance to the constructed tunnels was destroyed by explosives, causing the walls to crumble and tumble. Afterward, only a residual force of American soldiers remained to supervise the city of Naha and protect the aircraft that would be launching daily flights from the island to Japan.
Ten years had elapsed. It was now 1955. World War II was over, and I had stayed behind to assist in the assimilation of native and Japanese scientists in advancing science among the two countries.
Our projects focused on the study of biology in animal and plant life, but the baboon experiment would soon resurface and haunt us. Unknown to me and Dr. Yabu, who had been collaborating with me, Dr. Shimabuku—the Japanese scientist who had worked on the baboon experiments—had kept the project active. He had reopened the dreary tunnels of the military compound through another passage that led to secret caves near Mount Yonaha. The absolute terror of the feral and mutant baboons unleashed would terrorize the entire city of Naha and its people.
One day in the spring of 1955, a disturbing report of dead villagers in Kunigami made news in Naha. According to several witnesses, large and savage monkeys had attacked the peasant villagers unmercifully. The local police of the Prefecture dismissed the accounts, attributing the attackers to enraged lemurs or macaques with rabies. When I heard of the unfortunate tragedy, my recollection was not, at first, ascribed to the baboon experiment of ten years ago.
Dr. Yabu's response to the recent tragedy was marked by unwavering certainty. Without hesitation, he implicated Dr. Shimabuku in the attack. When I inquired about the basis of his conviction, he merely stated, "Dr. Shimabuku is involved—somehow."
His confidence was compelling. Recalling the baboon experiment conducted a decade earlier during the war, I remembered the army's destruction of the tunnels and their refusal to address the fate of the baboons. The unsettling reality of that time resurfaced.
Captain Holden had perished in the Battle of Ukishima, and the military compound lay in ruins. Few clues remained to shed light on the assault on the villagers, save for the accounts of eyewitnesses.
Determined to investigate, Dr. Yabu and I journeyed to Kunigami, a village nestled in the valley of Mount Yonaha. Upon presenting ourselves as scientists, we received permission from the authorities to examine the site. However, I noted their skepticism regarding the possibility of wild baboons being the culprits. This disbelief was perplexing, as baboons were not native to Okinawa. The notion of killer baboons intrigued me.
Upon reaching Kunigami, the aftermath of the attack was evident. The devastation was unlike any typical monkey raid; it exhibited a level of strength and savagery that suggested a deliberate assault by a formidable force.
This was no random act of nature. Dr. Yabu remained adamant that mutated baboons were responsible, and he held Dr. Shimabuku accountable for their creation.
The gravity of the situation was clear in Dr. Yabu's demeanor. He was certain of the events from ten years prior. I had no reason to doubt his account. He spoke of the unrestrained aggression of these unnatural baboons—beasts far from ordinary primates. If his concerns were valid, the pressing question was: where were these mutant baboons now?
Dr. Yabu pointed toward the dense Yanbaru Forest near Mount Yonaha. The rugged limestone terrain, surrounded by the villages of Kunigami, Higashi, and Ogimi, was a logical habitat for the creatures. He informed the authorities of the abandoned military compound, suggesting it might hold answers.
Accompanied by the Okinawan Police from Naha, who viewed our theory with skepticism, we ventured into the dilapidated compound. The facility, both inside and out, was in disrepair. Yet, Dr. Yabu believed Dr. Shimabuku had recently been there, continuing his experiments. His suspicion proved correct: Dr. Shimabuku had indeed created a new breed of baboons.
Though the tunnels had been destroyed ten years ago, Dr. Yabu was convinced that Dr. Shimabuku had perfected his work, producing more advanced and lethal creatures. This revelation raised further questions: What were these mutant baboons? And where were they now?
Dr. Yabu suggested the Yanbaru Forest as their likely location. Convincing the local authorities of this theory was challenging, but Dr. Yabu presented classified documents from the war that detailed the experiments, lending credibility to our claims.
As we entered the fog-laden Yanbaru Forest, a sense of foreboding enveloped us. The eerie silence was broken by the distant call of a primate. Deeper within, we discovered the gruesome remains of birds and children—heads severed, bodies mutilated. The carnage was beyond comprehension.
The question lingered: who—or what—was responsible for this unfathomable horror?
Whatever force had caused this anomaly of death had to be a destructive force of nature. The stench of the dead birds and children was overwhelming, a poignant smell that clung to the air like nothing I had ever encountered. The police officers who had joined us were both puzzled and horrified by the grisly scene, visibly uneasy in the eerie stillness of the forest. The children appeared to have been victims of the baboon attack on the village of Kunigami. I had never witnessed such a horrific scene of carnage, except on the battlefield.
The officers gripped their rifles tightly as we stood, horrified, staring at the devastation. It was clear that the macaques could not have been responsible for this slaughter, nor could any other monkeys. The images of the villagers' mutilated bodies were burned into my mind, impossible to forget. We heard the distant, guttural calls of the primates, but there was no sign of any baboons in the forest. It wasn’t until we ventured further and reached the edge of a narrow passage that we came face-to-face with an unnerving sight—an unnatural, mutant baboon. My mind reeled in disbelief as I stared at the grotesque size of the hybrid creature.
The trees cast long shadows over the beast, forcing us to adjust our position to get a better view. The sound of our footsteps startled it into a sudden, violent response. In an instant, the baboon lunged at the nearest officer, a man who had been helping with the search. With terrifying speed, it mauled him to death before he could even raise his weapon.
The second officer, paralyzed by fear, was too slow to react. Within moments, he, too, was killed. Dr. Yabu screamed at the third officer to shoot, and by some stroke of luck, he managed to fire in time, riddling the mutant baboon with bullets. The creature resisted with unnatural strength, but eventually, the barrage of gunfire brought it down. Unfortunately, the damage had already been done. The gunshots echoed through the trees, reverberating off the trunks and reaching the ears of the other mutant baboons who were lurking outside the forest.
I could feel their approach as we scrambled to flee, heading toward the forest’s edge in an attempt to escape the coming chaos. When we reached the outskirts, we saw them—an army of mutant baboons, advancing over the ridge. They didn’t spot us immediately, but their keen sense of smell told them something was amiss. We had to act fast, hiding in the underbrush, praying they wouldn’t find us.
One officer, the lone survivor of the earlier attack, wasn’t so lucky. The baboons noticed him, and he was torn apart in a savage, merciless assault. We managed to slip away undetected, but their scent had already filled the air, and we knew it wouldn’t be long before they found us. The memory of those mutant baboons—their immense size, their chilling calls—haunted me. Their thick fur and sharp muzzles were unforgettable, as was the sheer magnitude of their presence. They were all the same size, though they varied in appearance, but all exuded a terrifying power.
We ran until we reached the village of Kunigami, then took a vehicle back to Naha to inform the local authorities of the disaster that had unfolded in Yanburu Forest, including the deaths of the three police officers. We also urged them to evacuate the nearby villages—Higashi, Okimi, and Kunigami. The police were reluctant to believe our story about the mutant baboons, but eventually, they agreed to send officers to patrol the villages.
At first, the villagers were not evacuated. Only those who wished to leave could, but most chose to stay, placing their trust in the police. This decision would prove disastrous. No sooner had we arrived than the mutant baboons launched another attack on Kunigami. They came charging down the grassy slopes, their numbers overwhelming. A deafening call echoed across the valley. The villagers knew it was the baboons, and I could feel the same ominous anticipation.
The police officers seemed confused, unsure of how to respond. The villagers, however, reacted with swift panic, fleeing for cover. The hesitation of the officers would soon have grave consequences. The mutant baboons descended upon the village like a tidal wave, a terrifying spectacle of unfathomable savagery. This was the first time I had seen them in full force, and it was beyond anything I could have imagined.
By the time the police opened fire, it was too late. The baboons were too fast, too numerous. Though the officers managed to kill many, they were hopelessly outnumbered. The attack on the village was swift and brutal. Those officers who survived either fled in their vehicles or were left wounded by the overwhelming assault. The aftermath was a scene of utter chaos.
Miraculously, Dr. Yabu and I managed to survive the horrific attack. We took shelter under a house, surrounded by trees, as the violence raged on. But even as we lay there, our bodies trembling, I knew the nightmare was far from over. The mutant baboons were out there, and they would not stop until they had destroyed everything in their path.
I was certain that the trees had concealed our presence from the mutant baboons. It was a distinct possibility, yet one thing became glaringly clear: these were no ordinary baboons or primates. They were unlike any macaques or other monkeys known to exist in Okinawa or Japan. The terrifying thought of a wild, mutant horde of baboons wreaking havoc across the villages was a horror I could hardly fathom.
At the Prefecture of Police, we were forced to consider every means possible to eliminate the barbaric creatures before they claimed more lives. We later learned that the mutant baboons had attacked the villages of Higashi and Ogimi with unprecedented ferocity. Observing them was no longer enough; we had to understand their complex nature and hostility. These baboons were not only fearsome but also unnaturally persistent.
They were undeniably commiscible, a result of being bred from different cell structures within the baboon family. Their canines were enlarged and sharper, and they all sported manes—a bizarre anomaly, as not all baboons possess them. Their long, downward-sloping faces, however, were the most unnerving feature, leaving villagers frozen with terror.
I couldn’t determine whether the group had a traditional dominance hierarchy, but their expressions and tactics hinted at something more deliberate. The vocalizations they made were far more complex than the usual baboon calls. It was becoming increasingly clear that these creatures were not acting on instinct alone; they were capable of higher-level coordination and aggression.
Dr. Yabu and I both knew that the situation required immediate attention. The baboons’ behavior, their intelligence, and their organized violence made them a pressing threat. We couldn’t afford to wait for more lives to be lost. As we discussed our options, Yabu, ever the rational thinker, urged us to involve the Americans in the matter. Given the gravity of the situation, it seemed prudent to call in experts who might offer crucial insight.
His suggestion was welcomed. Dr. Yabu, a respected scientist, had long been trusted by the Ryukyuans. While many Okinawans had abandoned their native Uchinaaguchi in favor of Japanese, Yabu had remained a steadfast champion of his cultural roots. His reputation alone gave weight to our case.
The baboon attacks were like kamikaze strikes—unrelenting, audacious, and methodical. I was convinced that these creatures were not merely acting out of territorial instinct or unchecked aggression. Their attacks seemed purposeful, almost tactical, suggesting an intelligence that went beyond the natural behavior of primates.
Our only course of action was to capture one of the baboons alive for study. But even that posed significant risks. We could not proceed without the necessary knowledge of their biology and behavior, and that meant confronting them head-on.
We traveled to the Yanbaru Forest, the last known location of the mutant baboons. A sense of foreboding washed over me as we ventured deeper into the subtropical evergreen forest. The usual sounds of wildlife—like the Okinawan woodpecker or rail—were absent, which only added to the unease. With every step, I became more certain that something unnatural lurked ahead.
Then, the unmistakable calls of the mutant baboons broke the stillness of the forest. From behind the trees, they surged forward, an uncontrollable, lethal force. The police fired, managing to take down a few, but there were too many. The baboons overwhelmed us, forcing us into a desperate flight toward the village.
We barely made it out, but the baboons were relentless. They pursued us all the way to Naha. By the time we reached the city, chaos had already begun. The police, soldiers, and civilians were caught in a frenzy of terror as the mutant baboons descended on the city, seemingly out of nowhere.
They attacked indiscriminately, cutting down anyone in their path. Despite the arrival of American and Japanese military personnel, it was clear that we were too late. The city of Naha was swiftly overtaken, its streets littered with the bodies of those who had been unfortunate enough to cross the path of the baboons.
But just as suddenly as they had arrived, the baboons retreated, vanishing back into the mountains. The city, once a bustling hub, was left in ruins, its population decimated. It wasn’t long before news of the attacks spread beyond Okinawa, sending shockwaves through Japan. Cities across the nation—from Kagoshima to Tokyo—went on high alert, bracing for the possibility of further incursions. The sense of terror was palpable. It had been decades since Japan had experienced such a widespread panic, not since the bombings of World War II. The islands of Honshu, Hokkaido, Kyushu and Shikoku were threatened.
The United States Army was unwavering in its commitment to eradicating the mutant baboons. Dr. Yabu and I briefed the commanding officer, detailing everything we knew about the creatures. I emphasized the urgency not only to eliminate the baboons in Yanburu Forest but also to destroy the military installation at Mount Yonaha.
There was a military base nearby, about a mile away, where Marines were stationed and called upon to neutralize the baboon threat. Fully armed and prepared, we set out for Yanburu Forest to confront the mutants. Before our departure, we had received crucial intelligence about Dr. Shimabuku’s capture in Fukushima, Japan. He had provided us with the necessary information on how to defeat the mutant baboons.
At the village of Kunigami, we finalized our plan and proceeded toward Yanburu Forest. The morning sun blazed down on us, blinding our eyes for a moment, but we knew the baboons were out there, silently watching our every move. The tension in the air was palpable, our anxiety mounting as we ventured deeper into the forest. Our hearts raced in anticipation of the inevitable confrontation.
We could sense, the weight of the task ahead pressed down on us. The trees loomed like silent sentinels, their twisted branches arching overhead, blocking out the sun in places and casting eerie shadows on the forest floor. The air was thick with the smell of damp earth, and every step we took seemed to echo in the stillness, as if the entire forest was watching us, waiting for something.
I couldn’t shake the feeling that we were being followed. I turned to Dr. Yabu, who was walking just ahead of me, his face set in grim determination. His usual calm demeanor was nowhere to be found—he was just as anxious as I was. The thought that we might be walking into a trap sent a shiver down my spine, but we couldn’t turn back now. We were the only ones who knew the truth about what had happened here, and it was our responsibility to put an end to it.
As we rounded a bend in the path, I suddenly stopped, my heart leaping into my throat. There, hidden in the underbrush, were the bodies of several soldiers. Their faces were frozen in expressions of terror, their limbs contorted in unnatural positions, as though they had been caught off guard by the creatures. The sight of them, mangled and lifeless, sent a chill through me, and I knew at that moment that we were no longer dealing with ordinary animals. These mutant baboons were something far worse.
Dr. Yabu knelt down to inspect one of the bodies, his hands trembling slightly as he checked for any signs of a struggle. "Rabies," he muttered under his breath, his voice low. "The virus... it accelerates their aggression, heightens their strength. It makes them unpredictable."
Before I could respond, a shrill scream pierced the air, cutting through the tension like a knife. I whipped my head around, and there, emerging from the dense thicket of trees, was a massive mutant baboon. Its eyes glowed with an unnatural yellow hue, and its sharp teeth gleamed like daggers in the dappled light. It roared, an ear-splitting sound that reverberated through the forest, before charging directly at us.
Instinct kicked in. I drew my weapon and fired, but the baboon moved too quickly. It was upon us in an instant, slashing with its claws and biting with a fury I had never seen. The first soldier to be struck fell to the ground, blood pooling around him, his face a mask of agony. It was chaos. Bullets rang out, but the baboon’s skin seemed impervious to most of them, and its relentless assault didn’t slow.
I fought to hold my ground, but the beast was too strong, too fast. I managed to land a shot in its chest, but it barely flinched, continuing its rampage. The battle raged on, each moment blurring into the next. Soldiers fell. Baboons died. But the virus spread like wildfire, and the creatures kept coming, driven by an insatiable hunger.
At last, after what felt like an eternity, the beast staggered back, collapsing to the ground. It was dead, but the damage had already been done. We had lost too many men. The forest was now a battlefield, littered with bodies—both human and baboon. It was only then that I realized the full extent of Dr. Shimabuku's madness. These creatures were never meant to be defeated; they were a weapon, a horrific experiment meant to destroy us all. The creatures retreated, but they returned with full force.
From the dense foliage and sprawling branches, the mutant baboons launched their second attack. They descended on us like a bolt of lightning, striking with deadly precision. Their long, jagged claws and powerful jaws tore into our men instantly.
Although many of the baboons were killed in the ensuing chaos, the casualties among the soldiers were high. It wasn’t the soldiers’ bullets that ultimately stopped the menace of the mutant baboons. Instead, it was the very same virus that had been injected into them at their creation—rabies.
After the encounter in Yanburu Forest, the surviving mutant baboons began to succumb to the effects of the rabies virus, their bodies slowly deteriorating.
As we regrouped and surveyed the aftermath of the battle, the reality of our situation began to sink in. The mutant baboons had all but decimated our ranks, and the forest was eerily silent, save for the occasional rustling of leaves. The screams had stopped, replaced by the faint drip of blood from the fallen soldiers.
I glanced at Dr. Yabu, whose face had grown pale. He was staring at the lifeless bodies of the creatures, as though seeing them for the first time. "This…this is what we’ve come to," he whispered, his voice hoarse. "This was never meant to happen. We should have stopped Shimabuku sooner."
"We did everything we could," I replied, my voice flat. "Now we finish this."
But even as I said the words, I couldn’t help but feel a growing unease. We had killed the mutant baboons, but their deaths had come at a terrible cost. The virus was still out there, and the damage had already been done. It was too late for any of us to undo what had been started.
The forest was deathly still, the silence only broken by the occasional rustle of leaves or the distant call of a bird. We had just finished cleaning the battlefield, the remnants of both the soldiers and the mutant baboons scattered across the ground, lifeless. The once-vibrant woods of Yanburu now felt like a graveyard, a place forever scarred by the horrors we had witnessed. The sun was beginning to set, casting long shadows over the scene, and I felt the weight of our loss pressing down on me like a heavy cloak.
Dr. Yabu and I stood by the remains of the last mutant baboon, its grotesque body slumped against a tree. The fire in its eyes had long faded, and the eerie yellow glow that had once filled them with an unnatural fury was gone. The monster was dead, but I couldn’t shake the feeling that something even worse still lingered in the air.
"We’ve done it," Dr. Yabu murmured, though his voice lacked conviction. "But the cost…"
I nodded. The soldiers we had brought with us were either dead or gravely injured, and I knew there would be no way to fully recover from what had happened here. But it was over, wasn’t it? The mutant baboons had been eradicated, and Dr. Shimabuku’s twisted experiment had finally been put to rest. There was nothing more to do here.
But as the last light of day began to fade, a strange sensation crept over me. It wasn’t fear, but something far worse—something unexplainable, gnawing at the edges of my mind. Something wasn’t right.
"Dr. Yabu," I said, my voice barely above a whisper. "Do you feel it?"
He turned to me, his brow furrowed, and then looked around the forest, as though searching for something. He took a deep breath, as if steeling himself for what was to come. "I don’t know," he said slowly. "But I think we should leave. Now."
Before I could respond, the hairs on the back of my neck stood on end, and I heard it—an almost imperceptible whisper, like a rustling in the leaves, a sound that didn’t belong. It was too quiet to be the wind, too rhythmic to be an animal. I turned, scanning the trees for any movement. But there was nothing.
And then I heard it again. Louder this time.
It was a voice. A voice I knew all too well.
"Doctor..."
I spun around, my heart racing, and there—standing just beyond the treeline—was Dr. Shimabuku. His gaunt face was even more twisted than before, his eyes gleaming with madness. His clothes were torn, and his body looked as if it had been ravaged by time, hunger, and the very experiments he had orchestrated. But there was something else, something darker that clung to him like a shadow.
"You should have left," he continued, his voice cold and calculated. "You think you’ve won, don’t you? You think that destroying the baboons was the end of this nightmare? You think I was the only one who had a hand in this?"
I felt a chill crawl up my spine. Something was wrong. Something was deeply wrong.
"What are you talking about?" I demanded, stepping forward. "You’re the one behind this madness, not anyone else. We ended it. It’s over."
Dr. Shimabuku’s smile widened. It was a smile filled with triumph, but there was something else in it—a sense of impending doom. "Oh, it’s far from over," he replied, his voice almost a whisper. "You see, I never intended for the mutant baboons to be my final creation. They were just the beginning, a prototype. What you’ve done here, what you think you’ve stopped, is nothing more than a small piece of the puzzle. You’ve been too blind to see the truth."
I took a step back, confusion and fear swirling in my mind. "What truth?" I demanded. "What are you talking about?"
Shimabuku’s eyes gleamed with an unsettling fervor. "The true experiment," he continued, his voice growing more animated, "wasn’t about creating stronger, deadlier creatures. It wasn’t even about the virus itself. It was about something far greater. Something…far more terrifying."
Dr. Yabu’s face paled. He had been silent throughout the exchange, his gaze fixed on Shimabuku as if trying to make sense of his words. Finally, he spoke. "What are you saying, Shimabuku? What’s the true experiment?"
Shimabuku’s laugh echoed through the forest, sharp and unsettling. "The virus was just a means to an end," he said, stepping forward, his shadow stretching across the ground. "You see, I wasn’t the only one experimenting. There were others. Forces you can’t even begin to comprehend. The baboons, the mutation—they were just the beginning. The real experiment was to test the virus on something far more dangerous."
I felt a wave of dread wash over me as I realized what he was implying. "You didn’t…"
He nodded slowly, a twisted grin creeping across his face. "I didn’t just create mutant baboons. I created…a weapon. A virus that could be used on humans."
The words hung in the air like a death sentence. My heart stopped. The weight of what he was saying settled into my bones.
"You can’t be serious," Dr. Yabu whispered. "You never…"
"I did," Shimabuku said, cutting him off. "And now, the world is on the brink of something far worse than you can imagine. The virus is not just limited to animals. It’s a pathogen designed to rewrite the very fabric of human biology. It can make the strongest man into something… otherworldly."
"But why?" I asked, my voice shaking. "Why would you do this?"
"Because," Shimabuku’s voice dropped to a whisper, "I wanted to create the perfect being. I wanted to unlock humanity’s true potential. The virus will do that. It will make them stronger, faster…more powerful. And it will change the course of history. I’ve already begun the process. It’s too late to stop it now."
Dr. Yabu looked at me, his expression one of sheer terror. "What do we do?"
For a moment, I was paralyzed by the magnitude of what Dr. Shimabuku had done. The baboons had been only a distraction. The real horror was about to unfold. I knew, without a doubt, that we were standing on the precipice of something far worse than any of us could have anticipated.
Shimabuku’s grin grew wider, as though savoring our fear. "The world is mine to remake now. And you? You will be the first to witness it."
Dr. Yabu and I stood there in stunned silence. We had defeated the mutant baboons. We had ended Dr. Shimabuku’s initial experiment. But we hadn’t stopped the true nightmare. It was just beginning.
Dr. Shimabuku, the man behind the creation of these mutant creatures, had designed them to exist for only a specific period. His twisted vendetta against the Americans and Okinawans had driven him to resume his deadly experiments from 1944. In the end, his madness caught up with him. He was found insane, and institutionalized in a psychiatric hospital in Tokyo.
The military compound near Mount Yonaha was destroyed, never to be rebuilt, and any trace of the mutant baboons was erased from Okinawa's history.
The U.S. Government was determined that the documents from the military compound, containing information on the mutant baboon experiment, would never be discovered or made public. They were classified as top secret, and I was ordered to comply with that directive, forbidden from revealing any details about the experiments.
The Prefecture of Police in Okinawa, along with the United States Civil Administration, officially attributed the mutant baboon phenomenon to a rabies outbreak among primates brought to Okinawa by the Japanese during the war. Of course, Dr. Yabu and I knew the whole truth.
