The class buzzed with excitement as Aizawa led them into the massive dome of the Unforeseen Simulation Joint. Cementoss and Thirteen stood waiting near a central platform, surrounded by zones meant to replicate natural disasters.
Jason casually walked beside Momo, hands in his pockets. "You think we'll actually do anything today?"
Momo gave him a look. "This is important, Jason. Real rescue training."
He smirked. "Yeah, yeah. Just don't let a fake landslide bury you."
Thirteen began explaining the purpose of the USJ when the lights flickered.
A violet vortex spun into existence near the fountain. Kurogiri appeared, his voice calm and menacing. "So many promising students… it would be a shame if none survived."
Dozens of villains poured in.
Aizawa immediately activated his Quirk. "Thirteen, protect the students. Jason, stay near Yaoyorozu!"
Jason clicked his tongue, already pulling Momo behind cover. "Well, this got interesting fast."
Chaos erupted. Villains scattered the students. Kurogiri warped them across zones. Jason and Momo landed in the landslide zone—debris and rock pillars everywhere.
Jason landed on his feet, helping Momo up. "You good?"
She nodded, shaken but focused. "We need to regroup."
They fought through low-tier villains with sharp efficiency. Jason didn't use his full Quirk—just quick shapeshifts to dodge and outmaneuver.
Then the air shifted. The ground rumbled.
At the fountain, the Nomu appeared—massive, twitching with raw power.
Kurogiri's voice echoed. "Designed to kill All Might."
Jason's eyes narrowed. "You brought that thing here?"
He moved without hesitation.
Teleporting with a burst of shadow-like distortion (from his Quirk's morphing), he appeared behind the Nomu mid-charge. He shifted his arms into sharp-edged blades, slashing at tendons. The Nomu barely reacted.
Jason's grin sharpened. "You don't break easy. Cool."
The Nomu turned, roaring. Jason dodged the incoming punch, shifting his lower half into a coiled spring to rebound off a wall, landing a crushing blow to its side.
"Let's see how you handle a hundred versions of me."
From his body, a wave of gray clone variants burst out—less durable, but fast. They swarmed the Nomu like bees. Each time the Nomu smashed one, Jason would use the distraction to land precise blows.
He created a hardened spike-arm and jammed it into the Nomu's eye. The beast screeched and swung—Jason let his torso stretch and twist unnaturally to avoid the impact.
Nomu grabbed him finally, lifting him for a fatal slam—but Jason's body shimmered, slipping out like liquid.
"Nice try, Frankenstein."
With his hand transformed into a core-piercing drill, Jason punched into the Nomu's chest, aiming for the regenerative core.
"Evolve: Breakdown Pierce."
The drill pulsed and shredded the core apart.
The Nomu gurgled—then collapsed, motionless.
Just as Jason stepped back, breathing heavily, All Might arrived in a thunderous crash, cape billowing.
He saw the defeated Nomu—and Jason standing beside it, cocky as ever.
"I was just warming it up for you," Jason quipped with a grin.
All Might's eyes widened.
"…What are you, kid?"
