In the city of Otheon in Europe, Flect Turn, the leader of Humarise, stood silently in a grand hall that felt more like a cathedral than a headquarters.
The ceiling stretched impossibly high, and across it flickered massive hologram screens, each displaying different cities from around the world.
Beneath those screens, rows upon rows of Humarise members stood in perfect formation, clad in medieval armor and gripping spears like soldiers awaiting divine command.
Flect Turn's gaze drifted upward for a moment, settling on the massive carving embedded in the ceiling—a grotesque beast, half tiger and half buffalo, looming over everything like a silent omen.
Then, slowly, he lowered his eyes back to his followers. In his arms rested a book, its cover worn yet ominous—Quirk Doomsday Theory.
He raised it slightly, his voice calm but heavy.
"A long time ago… why was mankind given meta powers… otherwise known as quirks?"
The hall fell into complete silence.
"Why was the first metahuman… the luminescent baby… born?"
At his words, several members turned their spears toward a statue placed near the front—a baby lying peacefully in a cradle of carved flowers.
The contrast between innocence and fear was almost suffocating.
Flect Turn's expression darkened.
"It was not a miracle… it was a tragedy."
"Quirks were not a blessing for mankind… but the dawn of doom."
He lifted the book high into the air now, his voice echoing through the hall.
"As the Quirk Doomsday Theory states… quirks integrate and intensify through generations."
"There will come a time… when they evolve beyond human control."
His eyes sharpened.
"And when that day comes… they will bring humanity's extinction."
A murmur ran through the crowd, but no one dared interrupt.
"As the 20 percent population of quirkless pure people diminishes… due to interbreeding with the 80 percent quirked population… the world will become impure."
"The disease known as quirks… will consume everything."
His voice rose, filled with conviction.
"The world will soon be extinct of pure humans."
He hugged the book tightly against his chest. "It is now time… for us… Humarise… to take a stand."
"Even if it means bloodshed… we must save mankind."
"SAVE MANKIND!"
"SAVE MANKIND!"
The chant erupted instantly, thousands of voices shaking the hall as spears slammed against the ground in unison.
Flect Turn slowly raised a dagger into the air. Its gemstone pulsed faintly.
"Let us begin."
He pressed a hidden switch on its handle and pointed it toward the holograms above.
The screens sharpened, revealing live feeds from cities across the globe—Otheon, New York City, Tokyo, Hiroshima, Singapore, Cairo, Paris, Mumbai, Delhi, London, Los Angeles, Seoul, Shanghai, Berlin, Rome, Moscow, Toronto, Bogotá, Lagos, Dubai.
The gemstone flared.
A beam of light shot upward—and struck Paris.
Far beneath the hall, hidden deep underground, a massive machine activated. At its center, a glowing purple sphere pulsed violently, feeding energy into unseen channels.
Paris was alive, as it always was. People walked through the streets, laughing, talking. Heroes patrolled the skies. Cars moved. Life continued.
Suddenly, Green gas began pouring out from sewer drains.
At first, no one knew what was happening.
The gas spread unnaturally fast, swallowing streets, buildings, entire districts within seconds. Panic exploded as civilians tried to run—but it was already too late.
"A—AAAHHH—WHAT'S HAPPENING?!"
"My quirk—! I can't—control it—!"
A man raised his hand instinctively—flames burst from his fingers, but they didn't stop. They grew, consumed him, and within seconds he was gone, reduced to ash by his own power.
Nearby, another person collapsed, their body warping uncontrollably—transforming into a turtle mid-scream—before going still, blood pooling beneath them.
A woman fell to her knees as invisible forcefields erupted around her. Buildings cracked, then tore from their foundations, spinning wildly in the air.
"MAKE IT STOP—!" she screamed, blood streaming from her eyes, nose, ears—and then silence.
Across the city, quirks spiraled out of control.
Explosions, transformations, energy bursts—everywhere at once. The very powers people relied on became the instruments of their deaths.
Back in Otheon, the Humarise members watched and cheered.
"SAVE HUMANITY! SAVE HUMANITY!"
Their voices rang with twisted triumph as the screens displayed nothing but destruction.
Minutes later… the gas vanished.
Paris fell silent.
No movement.
No sound.
No life.
Only destruction remained.
Amid the ruins, one man crawled forward, shaking violently. His eyes darted around at the corpses, the collapsed buildings, the horror that surrounded him.
"I… I…"
Footsteps approached.
A Humarise member stepped into view, opening the back of a van.
"Congratulations," he said calmly, grabbing the man by the arm. "You are a pure human… unlike those quirked freaks."
Back in Otheon, the chants grew louder.
"SAVE HUMANITY!"
"SAVE HUMANITY!"
Flect Turn stood at the center, unmoving, the book still held tightly in his hands.
Not far from the hall, one armored knight slipped away unnoticed. His breathing was heavy as he ran through a hidden passage, pulling out a small radio.
"H-hello—! This is—!" he whispered urgently. "Requesting immediate contact with the World Heroes Association—this is an emergency—!"
Far away, inside the Nova Genesis base, silence filled the room.
A massive screen displayed the aftermath in Paris.
No one spoke.
Melissa's hands trembled slightly. David's expression had gone pale. Even Kaina, who had seen countless horrors, stared in shock.
"…They wiped out an entire city…" Tobita muttered.
No one disagreed.
Only Arata remained still.
His eyes shifted—from the screen—to the chamber at the center of the room.
Inside it, the two Infinity Stones hovered quietly, glowing with immense power.
"…So it's begun."
His gaze hardened.
"Looks like we will have to pay a visit to Otheon soon."
