CHAPTER 9: Unseen Shadows
The sky was overcast as Class 1-A gathered outside the U.A. campus, the buzz of excitement rippling through the students. The field trip to the Unforeseen Simulation Joint—the U.S.J.—was all anyone could talk about, though there was a subtle undertone of nerves among them. Disaster simulations weren’t exactly light training, and from the way Aizawa-sensei had worded it, this wasn’t going to be just another exercise.
You adjusted the straps on your U.A. gym uniform as you boarded the bus with the others, finding a seat near Uraraka and Iida, who were chatting animatedly about the upcoming training. You weren’t as talkative, your mind drifting to everything that had happened since the Battle Trial. Bakugo’s harsh words still stung, and even though you were determined to get better, the weight of self-doubt hadn’t fully left you.
Midoriya sat nearby, glancing over at you every so often, probably sensing your quiet mood. He didn’t say anything, but his presence was always a comforting one. Still, the knot in your stomach wouldn’t go away. You had a feeling that something was off today—something you couldn’t quite place.
"Everything alright, Mizushima?" Iida asked, breaking through your thoughts.
You nodded quickly, forcing a small smile. "Yeah, I’m fine. Just a little nervous, I guess."
"Don’t worry!" Uraraka chimed in, her usual upbeat tone lifting the mood. "I’m sure we’ll do great. It’s just another simulation, right?"
Her words were meant to comfort, but you couldn’t shake the lingering sense of unease that had settled in the pit of your stomach. Something about today felt… wrong.

As the bus arrived at the U.S.J., you couldn’t help but feel a chill in the air. The massive dome structure loomed ahead, and inside, you knew the disaster zones awaited you: areas designed to simulate floods, landslides, fires, and other emergencies. It was meant to be a training ground for heroes, a place to test your abilities in high-stakes scenarios. But as you stepped off the bus, the unease in your chest only grew stronger.
"Welcome to the Unforeseen Simulation Joint!" Thirteen, the pro-hero in charge of the facility, greeted the class with her warm, calm demeanor. Her presence was reassuring, but even she couldn’t shake the tension that hung in the air.
You stood near the back of the group, listening as Thirteen explained the layout of the U.S.J. and what you’d be facing today. But as her words echoed through the space, you found your attention drifting again. Your eyes scanned the wide-open room, taking in the various disaster zones—floods, fires, debris fields. And yet, your gaze kept pulling toward the shadows beyond, as if something—someone—was watching from the darkness.

Then it happened.
Without warning, the air around you seemed to crackle, and from the center of the U.S.J., a dark portal began to spiral open. The ominous, black mist spread like smoke, and out from it stepped a group of unfamiliar figures—figures you knew weren’t part of the simulation.
The chill that ran down your spine was instant.
"Villains!" Aizawa-sensei barked, his eyes narrowing as he stepped forward, scarf already unraveling as he prepared for battle. "Everyone, stay back!"
Your heart pounded in your chest as you took a step back, your mind racing. This wasn’t a drill. This wasn’t part of the exercise. These were real villains.
Among the figures, you spotted a hulking man with hands covering his body—and beside him, a tall figure made entirely of black mist. Your eyes darted to the other members of the League of Villains, but one figure in particular caught your attention.
A woman.
She stood slightly behind the others, dressed in dark, ragged clothing, her face hidden beneath a mask that only revealed her piercing eyes. Something about her sent a shiver down your spine, but you couldn’t place why. Her gaze swept over the group of students until, suddenly, her eyes locked onto yours.
For a moment, the world seemed to fall away. Her gaze bore into you, filled with something you couldn’t quite decipher. Anger? Hatred? You had never seen this woman before, but the way she looked at you—it was as if she had known you for a long time.
"Class 1-A!" Aizawa’s voice snapped you out of the daze. "Get out of here, now!"
The students began to scatter, panic spreading through the group as the villains advanced. But you couldn’t move. You were frozen in place, your mind racing as the woman continued to stare at you with that unsettling intensity.
Why was she looking at you like that? Who was she?
"Mizushima!" Midoriya’s voice pulled you back to reality, and you quickly turned to see him rushing toward you. "We need to move!"
You nodded, shaking off the fear that had paralyzed you. "Right, let’s go."
But just as you turned to follow him, a blast of energy shot through the air, striking the ground near your feet. You stumbled back, and when you looked up, the masked woman was advancing toward you, her eyes locked on yours.
"You," she hissed, her voice dripping with venom. "I’ve waited a long time for this."
You froze, your mind racing. What was she talking about? Who was she? You didn’t know her—you were sure of it. And yet, there was something about her that felt eerily familiar.
Before you could react, Aizawa stepped in, his scarf snapping toward the woman, but she dodged it with a swift movement, her eyes never leaving yours.
"You don’t even remember me, do you?" She snarled, her voice low and dangerous. "Pathetic."
The accusation hit you like a punch to the gut. Your mind reeled as you tried to make sense of her words. Remember her? How could you? You’d never met her before—at least, not that you could recall. But the hatred in her voice was unmistakable, and it was directed entirely at you.
Before she could strike, Aizawa’s scarf wrapped around her arm, pulling her back. "Get out of here, Mizushima!" he ordered, his voice firm.
You hesitated for a moment, torn between staying to fight and running as Aizawa had commanded. But the fear in your chest won out, and you turned, following Midoriya as the class began to scatter into different disaster zones.
As you ran, your mind raced with questions. Who was that woman? Why did it seem like she hates you? Do you know her? But why couldn’t you remember her?
Midoriya’s voice pulled you out of your thoughts. "Mizushima! Are you okay?"
You nodded, but the truth was, you weren’t. "I—yeah, I’m fine. I just… I don’t understand. That woman was looking right at me, like she knew me."
Midoriya’s face was filled with concern as he glanced back at the chaos unfolding behind you. "We need to stay focused. Aizawa-sensei will handle them, but we have to get to safety."
You nodded again, but the woman’s words echoed in your mind: "You don’t even remember me, do you? Pathetic."
Something told you this was far from over.
