My Hero Academia: Thunder God

Within ten minutes, under the energetic command of Class President Iida, the boys and girls of Class 1-A, now dressed in their Hero costumes, boarded the bus arranged by U.A. High School in an orderly fashion.

It was the same bus that had taken them to the 'Seven Simulated Communities' during the entrance exam.

However, Midoriya was still dressed in his standard gym uniform. His Hero costume had been damaged during his fight with Bakugo and was sent to a sponsor company for repairs.

"Speaking of which, Kaminari," Tetsutetsu, sitting next to Kaminari, spoke up, looking puzzled. "All Might mentioned that your current combat uniform was made by your old sponsor, right? What about the new one from the current sponsor? Hasn't that come out yet?"

"Not yet, it seems," Kaminari said, looking down at his current combat uniform, a striking gold and white robe. "But honestly, I really like this one. It looks... pretty awesome, don't you think?" He grinned.

It was worth mentioning that just the night before, Kaminari had received a call from a company owned by Mitsui. They wanted to incorporate his gloves into a new Hero costume and asked for his approval.

Kaminari had consulted his father, called Mitsui for more details, and ultimately agreed to their request. According to Mitsui, they planned to use the blue crystal in his Denki gloves as the core energy source for the new suit. It seemed this energy-storing crystal was a unique invention of "I-ISLAND."

Kaminari then glanced over at Tetsutetsu's combat uniform, which resembled a Self-Defense Force uniform, and couldn't help but smirk. "Did you design that yourself? No offense, but it's kinda… ugly."

Tetsutetsu scratched his head sheepishly. "Actually, my dad designed it. It's made out of iron, so I can literally eat parts of the suit to replenish my iron levels. He also thought military uniforms were the coolest, so that's why it looks like this."

Kaminari didn't argue. "Military uniforms are the coolest" 

But as he continued eyeing Tetsutetsu's uniform, another idea struck him.

"Hey, what if I designed a new combat uniform for you?" Kaminari suggested, leaning in excitedly. "I could make it super cool, like a military uniform, but way more stylish."

Tetsutetsu blinked, surprised by Kaminari's sudden burst of enthusiasm. "Kaminari…"

He hesitated for a moment but eventually gave in to Kaminari's eager expression. "Alright, sure."

"Of course!" Kaminari nodded, grinning widely. "Trust me!"

Kaminari couldn't help but imagine Tetsutetsu in a sleek, modernized military uniform. "That would look so badass," he thought, already excited about the possibilities.

Meanwhile, on the other side of the bus, Tsuyu and Kirishima were discussing Midoriya's Quirk. Tsuyu thought it seemed similar to All Might's Quirk, while Kirishima argued it couldn't be the same since All Might had never gotten hurt using his.

This made Kaminari glance over at Midoriya with a strange look. He had a bold theory about Midoriya's Quirk, but there wasn't enough evidence yet to support it.

"Could it really be the same power?" he wondered. If it was true, it meant they were in for some incredible and probably dangerous times ahead.

"Midoriya, I'll be watching you closely," Kaminari thought to himself, both intrigued and a little concerned.

The bus ride passed quickly, and soon enough, they arrived at their destination: a massive structure that resembled the Bird's Nest stadium from Kaminari's previous life.

"Students, I've been waiting for you!" A figure in a space suit greeted them enthusiastically at the entrance.

Kaminari blinked in confusion. He didn't recognize the person. "Who the heck is this?" Kaminari thought. 

He spent so much time training and studying Quirks, and what little time he had left went into learning guitar. As a result, he wasn't very familiar with many Pro Heroes, aside from the really famous ones.

Fortunately, someone else knew who this was.

"It's the Space Hero: Thirteen!" Midoriya exclaimed, clearly excited.

"A Pro Hero who specializes in rescue operations during disaster situations!" Midoriya added, almost bouncing with enthusiasm.

"I love Thirteen!" Uraraka squealed, her eyes sparkling with admiration.

"Thirteen? That's their Hero name? What an unlucky number..." Kaminari thought, a bit amused but also unimpressed.

As Aizawa joined the group, Thirteen motioned for the students to head inside, as the training session was about to start.

"Please, come in!" Thirteen said, welcoming them inside.

The class followed Thirteen and Aizawa into the massive training facility. As soon as they stepped inside, everyone was stunned by the sheer size and complexity of the place.

"Whoa, whoa, whoa… I knew U.A. was impressive, but this is on a whole other level!" Kaminari muttered, looking around in awe. 

The place was enormous, with different sections dedicated to various types of disasters. It was hard to believe this was just a part of U.A.'s campus.

U.A. was already massive, with its huge teaching buildings, cafeteria, swimming pools, and the expansive 'Seven Simulated Communities.' And now, this simulated disaster site...

Kaminari realized he might have underestimated U.A.'s true scale. "If U.A. is this impressive, what must the Hero schools in other countries be like?" he wondered, thinking of places like the U.S., China and Russia.

"The world is probably a lot bigger than I thought," Kaminari mused.

Thirteen began to introduce the facility with pride. "This training ground simulates all kinds of disaster scenarios floods, landslides, fires, storms, and more. I designed it myself!"

Thirteen spread their arms wide. "We call it the Unforeseen Simulation Joint!"

"The what?" the class mumbled in confusion.

"USJ!" Thirteen said, beaming.

The class couldn't help but share a collective chuckle at the cheesy abbreviation.

Aizawa, hands in his pockets, turned to Thirteen. "Where's All Might?"

Thirteen leaned in and whispered, "He used up all his power on his way here, so he's currently resting in the lounge."

"Of course..." Aizawa muttered, clearly not thrilled. "Well, we'll just proceed without him."

With that, Thirteen took over, explaining the purpose of the training.

"Unlike the combat training you did with All Might, today's session will focus on rescue operations. You'll learn how to use your Quirks to save lives during natural disasters and accidents."

"Your Quirks aren't just for fighting. They're meant to save people!" Thirteen said passionately. "I hope by the end of this session, you'll truly understand that."

Thirteen finished with a graceful bow. "Thank you for listening!"

The students, especially those familiar with Thirteen, erupted in cheers, clearly excited for the upcoming training.

"Thirteen's so cool!" Midoriya and the others gushed, looking like true fans.

Just as Kaminari was about to join in on the excitement, he felt something strange through his wireless earpiece. A strange frequency buzzed in his ear, setting off alarms in his head.

Moments later, the lights in the facility flickered and shut off, plunging the room into semi-darkness. The decorative fountains that lined the facility stopped working as well, and an eerie silence fell over the room.

"Something's wrong," Kaminari thought, his body tensing instinctively.

Aizawa's sharp eyes flicked toward the main fountain at the center of the room. In front of the fountain, a swirling vortex of black and purple energy began to form.

"What the...?" Kaminari whispered.

With a loud *pop*, the vortex expanded, and from it emerged a hulking figure made of dark energy. From its shadowy form, more figures began to emerge—strange, villainous-looking individuals stepping out of the void.

Aizawa's eyes narrowed dangerously, the intensity of a seasoned pro Hero flashing in his gaze. Years of fighting villains had honed his instincts, and this was no simulation.

"Everyone, stay together and don't move!" Aizawa barked, his voice sharp and commanding.

He turned to Thirteen. "You're in charge of protecting the students!"

The class stared in disbelief as more figures continued to pour out of the vortex. 

"What are those things?" Kirishima asked, confused.

"Is this part of the training?" he guessed.

"No," Kaminari said, his voice low. "This isn't a drill."

Aizawa confirmed Kaminari's fears. "Those... are villains."

Kaminari's heart raced. He had been mentally prepared for this kind of danger when he applied for the Hero Course, but now that it was happening, he couldn't help but feel a mix of excitement and anxiety.

"Is this really happening?" Kaminari thought, "...a real battle?"

Golden sparks flickered between Kaminari's eyes, his Quirk stirring in response to the adrenaline coursing through his veins. His hands crackled softly with electricity as he stared at the dark figures emerging from the portal.

"Come on, villains,"
