In MHA with JJK powers.

Here's an improved version of the chapter with added dialogue and better flow for Kaminari:

Kurokai, Jiro, Kaminari, and Kirishima stood in front of Momo's luxury traditional Japanese noble-like house.

"I didn't know Momo was a rich girl!" Kaminari shouted, his eyes wide in excitement as he looked around, taking in the size of the sprawling property.

Well, it was big—there was no end in sight.

"Suge... must be nice living in such a big place..." Kirishima said, his eyes sparkling with admiration.

Jiro couldn't help but glance at Kurokai, who was staring at the enormous door, lost in thought.

"Although it might be a bit inappropriate to ask," she said cautiously, "but... Kurokai-kun, why are you here?"

"Yeah, you're already top of the class! What extra lessons could you possibly need?" Kaminari chimed in, his voice full of teasing curiosity.

"Since you think it's inappropriate to ask, then don't," Kurokai responded, his tone calm, almost dismissive.

"What? Hey, I wasn't talking to you!" Jiro snapped, her face turning red. She quickly connected her earphones to Kaminari's body, zapping him with a mild shock.

"W-Wait, J-Jiro! Kyaah!" Kaminari yelped, wincing as his body jolted from the shock.

Kurokai, still staring ahead, was completely unfazed by the chaos around him. Jiro couldn't help but notice how composed he was, in stark contrast to the excited murmurs of her other friends. It was as if he was in a different world, unaffected by the extravagant property and the beautiful surroundings.

"Hey, Kurokai, is something wrong?" Kirishima asked, noticing his stillness.

Before Kurokai could respond, the electronic buzz from the front door signaled an incoming guest. A familiar voice echoed out.

"Everyone! I am sorry to have kept you waiting!"

The front door swung open, and there stood Momo, dressed in a stunning traditional dress that immediately caught the attention of everyone.

"Oh! It's Momo!" Kaminari and Kirishima exclaimed in unison, their eyes practically glowing as they admired her appearance.

Jiro shot them both a look, narrowing her eyes at their obvious admiration. "Perverts..." she muttered under her breath.

Kaminari and Kirishima, totally oblivious to Jiro's glare, followed Momo inside the house, their eyes glued to her attire.

'Kurokai-kun seems the most normal here,' Jiro thought to herself, noting how Kurokai was simply observing everything around him, not distracted by the luxury.

He wasn't fazed by the giant property, nor did he seem to care about the expensive decor. Even Jiro, who considered herself fairly composed, couldn't resist sneaking a glance at the surroundings from time to time.

Only Kurokai remained focused, his attention always forward, as if nothing else mattered.

"Then everyone, shall we start?" Momo asked, her hands folded together as she addressed the group.

After receiving nods of agreement, she continued. "How about we start with a little doubt session? This will help me gauge everyone's level."

Just as Momo was about to continue, Kurokai raised his hand.

Momo blinked, clearly surprised. "That… Kurokai-kun, we're not in class, so there's no need to raise your hand like that... and I don't think I can help solve your doubt. Sorry."

Kaminari, ever the joker, quickly interjected, "Momo, only you can answer his question."

"What? Really?" Momo replied, her curiosity piqued.

"That…" Kurokai began, his voice serious. "Do you have a brother or sister?"

Momo blinked, clearly confused. "I don't understand..."

"Do you have a sibling?" Kurokai clarified, his tone unwavering.

"Siblings? No, I'm an only child," Momo replied, still unsure of where this was going. "But... how is that related to the study session?"

"I've heard enough," Kurokai suddenly declared, standing up abruptly. The rest of the group looked at him in surprise.

"Hey, hey, Kurokai, what's going on?" Kirishima asked, his voice full of concern.

Ignoring Kirishima, Kurokai marched over to Momo, grabbing her hand with an unexpectedly serious expression. "Momo, let's get married."

"W-w-w-w-what?!?" Momo gasped, almost falling from her seat.

Kurokai held her hand firmly, making sure she didn't fall. Momo, wide-eyed, looked around frantically, searching for help.

"K-Kurokai! What are you doing?!" Jiro jumped up, her face flushed with embarrassment. "Aren't you and Asui already a thing?!"

'Is Kurokai that fickle?' Jiro thought, her mind racing. 'Has money really blinded his eyes? I was wrong to trust him! All men are trash!'

Meanwhile, Kurokai was continuing his pitch. "We're the same age, I'm 5'11", I don't have any bad habits—"

'—Except for a few,' he thought privately.

"—My telekinesis ability is strong, and I believe I could be the number 2 or 3 hero in the future. I think we'd be perfect together."

Momo's head spun from the sheer audacity of it all. "Kurokai, please stop..." she stammered, her face bright red.

Before Kurokai could say more, Kirishima patted him on the shoulder, forcing him to stop. "Alright, Kurokai, stop teasing her. Momo's getting uncomfortable."

Kurokai paused, then looked at Momo with a serious expression. "It wasn't a joke. You can consider it."

Momo's face flushed even more. "I-I don't see you that way, Kurokai-kun..."

"Ah, well, that's a shame," Kurokai said, his voice tinged with mock regret. He released her hand and returned to his seat as though nothing had happened.

Kirishima couldn't help but shake his head. "Well, that was unexpected."

Despite the chaos, the study session carried on, and surprisingly, things went smoothly.

Kurokai began explaining a complex concept, and even Kirishima and Kaminari couldn't help but admire his knowledge.

'Wow, he's actually good,' they both thought.

Kurokai's detailed explanations left everyone in awe. Even Momo, one of the top students in their class, was impressed by the depth of Kurokai's understanding. She couldn't explain things with the same level of clarity.

As everyone settled in, Kurokai casually added, "So, Momo, considering my theoretical knowledge, how about—"

"Please, Kurokai-kun, no more random bombs!" the group shouted in unison.

Kurokai only shrugged, unfazed by their reactions. "I was just going to ask for some funding to build a Gundam... I didn't think it would cause this much of a reaction."

The group groaned in exasperation.

Meanwhile, in a villain hideout, Mechamaru was plotting.

"Let's rob a bank," Mechamaru suggested nonchalantly.

Shigaraki and Kurogiri looked at him in surprise. "Why a bank?"

"Because we're poor," Mechamaru replied with a shrug, pointing to their rundown base. "And I want to build something..."

Shigaraki's eyes lit up. "Oh? What are you going to build?"

Just then, the TV flickered on, and All For One's amused voice echoed through the room. "Rob a bank? Sounds like a great learning experience."
