Plots
Intro
MHA. U.S.J ATTACK
Kirishima : “Woah… this place is huge.”
Uraraka : “So this is the U.S.J…?”
The automatic doors slid open with a deep mechanical sound and everyone walked in. The massive U.S.J (Unforeseen Simulation Joint) towered before them— a colossal indoor disaster facility divided into zones: floods, fires, landslides, shipwrecks, urban ruins, all designed to simulate real-world catastrophes.
Inside stood Pro Hero Thirteen, waiting at the center of the facility, her posture straight, hands folded. Beside her, leaning against the railing with a bored, half-lidded stare, was Shota Aizawa—sleep-deprived, scarf loose around his neck.
After the class gathered, Thirteen began her explanation.
*Thirteen : “Welcome to the Unforeseen Simulation Joint!! This facility exists to prepare heroes for rescue situations involving disasters—floods, fires, collapses—” She raised one finger.
Thirteen : “One wrong move here could cost lives. Remember—your Quirks are tools meant to save, not to show off.”
The students listened.Some nervous.Some excited. Aizawa sighed.
Aizawa : “We’ll start training soon. Don’t let your guard down.”
And then— FWOOOM. A low, unnatural sound echoed through the dome. The air twisted. At the center of the plaza, space itself began to fold inward— A dark, swirling portal, glowing with purple and black energy, tearing open reality. The ground vibrated, and and students froze. From the portal, figures began to fall out— one after another. Villains??
*At the front stepped a man with grey hair and crimson burning eyes, scratching his neck in anger, hiss face was hidden beneath disembodied hands one gripping his face, others crawling over his body like parasites.Next to him emerged another man whose body was a dark purple mist.
Behind them emerged something massive. A creature stitched together unnaturally. Bulging muscles. Blank eyes. A presence so oppressive that instinct screamed danger.At the command of the gray-haired man, the minor villains set off.
Before panic could spread—
Aizawa : “THIRTEEN—PROTECT THE STUDENTS!”
His voice was sharp. Absolute. In the same instant, Aizawa jumped forward, scarf snapping violently as he charged alone into the crowd of villains, eyes glowing as his Erasure activated. Shock hit Class 1-A.
Midoriya : “Aizawa-sensei—?!”
Thirteen spun around immediately, arms spreading to shield the class.
Thirteen : “Everyone, move! Head for the evacuation gate immediately!! This is no longer a training exercise!”
But suddenly—a black fog formed, blocking them all before they reached the gate. Kurogiri, a black fog, shifts, spreading wide before he speaks.
Kurogiri : “I apologize, but I can't allow that. We are the League of Villains—here to clear away the disease corrupting this society. There's just one person we came here for."
All chatter froze as everyone realized what that meant.
Uraraka : "T- The one All Might was supposed to be with…?"
Thirteen : "They knew about us, our schedule— our EVERY MOVE!!"
She wasted no time before suddenly pointing a finger at the villain, opening her costume right there.
Thirteen : "BLACK HOLE!"
