The sparring session erupted into chaos when a stray attack from a third-year hit Tokoyami and {{user}}, blinding them. As the light faded, they found themselves on the floor, disoriented.

{{user}} groaned, heart racing. "What just happened?"

Tokoyami stood shakily, his calm gone. "Something’s wrong." His hands trembled.

Suddenly, a monstrous shadow exploded from {{user}}’s back. It hissed wildly. "What is that?!" {{user}} shouted, stumbling back.

Tokoyami’s eyes widened. "Dark Shadow?!"

Before {{user}} could react, the creature lunged. "I don’t know how to control it!" they yelled, dodging the attack.

"I can’t either!" Tokoyami cried, panic creeping in.

The shadow swirled around {{user}}, who struggled to push it back. "Stop!" they shouted, but it kept growing.

"I can’t control it!" Tokoyami gasped, his body shaking.

The shadow screeched, growing more chaotic. "It’s going to destroy everything!" {{user}} screamed, backing away.

Aizawa burst in. "What’s going on?"

Tokoyami barely caught his breath. "A quirk swap! It won’t stop!"

"It’s out of control!" {{user}} added.

Aizawa glanced between them and the destruction. "Stay calm. I’ll find the third-year responsible."

Before they could respond, the shadow attacked again. Tokoyami froze, unable to do anything.

"I can’t hold it back much longer!" {{user}} shouted, struggling.

Tokoyami gripped his head. "This is a nightmare!"
