A Few Days Ago

"All Might, that kid is suspicious. We need to take action," said a man in formal attire, wearing glasses, in a grave tone as he sat opposite the Symbol of Peace.

All Might didn't refute his words, but he didn't agree either.

Seeing this, All Might's sidekick, Nighteye, adjusted his glasses before speaking.

"As your chosen successor mentioned, Kurokai approached him and revealed information he shouldn't have known unless he had been following you."

He paused before continuing in a calm voice, "He handed you this DNA report and even deliberately used words to provoke a reaction from you... His actions mirror those of a spy, though his motives remain unclear. You should also note, All Might, that the location and timing of the disaster dome were confidential, known only to a select few."

Nighteye's voice grew sharper. "Given that the teachers have been our trusted colleagues for years, it's more plausible that the spy is one of the students."

All Might sighed and raised the DNA report in his hand, reviewing it for what felt like the hundredth time.

"But Kurokai-kun helped the students and even saved me."

"That's precisely why I said his motives are difficult to determine." Nighteye frowned, deep in thought.

No matter how much he analyzed the situation, he couldn't find a convincing reason for Kurokai's actions.

Is it truly just a coincidence?

Nighteye shook his head. He didn't believe in such superficial explanations.

Though he wanted to interrogate Kurokai directly, the conflicted expression on All Might's face stopped him. For now, his suspicion hadn't reached the point of taking drastic measures, but if it came to that, he wouldn't hesitate.

Present Day

"Let me ask again, Teacher Midnight. Are you really not doing this because of a personal grudge?"

"Of course not, student Kurokai! This is purely to educate the students!"

"Hmph. So I'm supposed to believe it wasn't your idea to make me face a teacher alone while forbidding me from using my quirk?"

Hero Midnight simply responded with a bright smile and waved her whip threateningly.

Kurokai nimbly dodged the attack and created some distance. But instead of slowing down, her attacks only increased in frequency, making it seem less like a test and more like she was hunting a villain.

Unfortunately for her, even without his telekinesis, Kurokai's physical fitness, bolstered by cursed energy, far surpassed Hero Midnight's.

While dodging, Kurokai spoke casually. "Teacher Midnight, I can see through that fake smile of yours. Deep down inside, I know you're sad—"

"Silence, brat! Just die!"

In the observation room, the corners of Eraser Head's mouth twitched as he watched Midnight's villainous smile on the screen.

A student asked hesitantly, "Teacher Eraser… is Midnight-sensei okay?"

"...…"

Eraser Head chose to ignore the question entirely.

"MUDA! MUDA! MUDA! MUDA!"

"Teacher, is that a JoJo reference?"

"Shut up!"

Back in the arena, Midnight grinned as she released a pink pheromone-filled mist, blocking Kurokai's escape routes.

"Let's see where you'll run now, brat!"

Kurokai remained calm, locking his gaze on the approaching whip.

"This is what you get for—what?!"

Midnight's words halted mid-sentence as she realized the end of her whip was now in Kurokai's grip.

"You…"

"Mine!"

With a quick tug, Kurokai disarmed Midnight, leaving her whip in his hand.

Instead of panicking, Midnight smirked confidently. "You've lost, kid."

She declared this with certainty, knowing her pheromones had completely surrounded him.

But just as she thought victory was hers, an unsettling voice interrupted.

"I'm sorry, but... what's lost?"

"What?!" Midnight's eyes widened in shock. She couldn't comprehend how Kurokai remained unaffected by her quirk.

Before she could question him, Kurokai grinned. "It's my turn now, Teacher."

Raising the whip, Kurokai lashed it down, landing a precise hit on Midnight's rear.

But instead of an angry outburst, a sensual moan escaped her lips.

"Hmhm~"

Kurokai froze in horror, almost dropping the whip.

In the observation room, the students watching were utterly speechless.

Meanwhile, Eraser Head was already sprinting toward the arena to stop the madness.

After the Exam

Barely passing, Midoriya sat quietly on a mall bench, replaying the key moments in his mind. For some reason, a familiar girl's face appeared, causing him to blush.

"Oh! Is that a UA student? Wow, I've met a celebrity!"

Midoriya looked up, embarrassed, only for a slim arm to wrap around his shoulder. Turning, his heart sank.

It was a face he knew too well.

The villain with the power of decay.

Shigaraki grinned. "With a single thought, I could turn you to dust…"

Fear consumed Midoriya, but before he could scream, another arm wrapped around Shigaraki's neck.

"Wow, isn't this the leader of the villains? I caught a big one!"

Shigaraki froze as Kurokai restrained him effortlessly.

"KUROKAI-KUN!" Midoriya cried out, overwhelmed with gratitude.

But before anyone could react further, a cold metallic voice cut through the air.

"And what do you think you're doing to my best friend?"

The temperature seemed to drop as Mechamaru stepped into view, wrapping his cold metal arm around Kurokai's shoulder.

The roles reversed yet again.

'Mechamaru!', Shigaraki shouted with joy in his mind.

"K-Kurokai-kun.....", Midoriya muttered in a fearful voice.

On the other hand both Kurokai and Mechamaru grinned in their minds.
