My Hero Academia: Thunder God

"Uh… well, I'll need to discuss this with my family. Can you give me a day to think it over?" Kaminari asked awkwardly, scratching his head and forcing a sheepish laugh. Internally, he was already bracing himself. If Dad doesn't approve this, I'll have to forget about it. It's way too expensive.

"No problem," Dr. Tenma replied, hiding his amusement and nodding naturally. Just then, the artificial intelligence system, "Sadako," chimed in with a notification.

"Dr. Tenma, Tetsutetsu Tetsutetsu has arrived and is being escorted by Secretary Eguro Akemi."

"Oh? Perfect timing. Let him come straight in," Dr. Tenma said, motioning for Sadako to proceed.

Kaminari perked up at the news, a smile lighting up his face. He hadn't expected to meet Tetsutetsu this soon, and the thought made him genuinely happy.

I wonder if this guy has gotten stronger. If not, he's going to fall even further behind me, Kaminari thought with a chuckle.

He knew Tetsutetsu's determination well, so he had shared the basics of the "Six Styles" with him before. He hoped it would give his friend a long-term goal to work toward.

Still, he couldn't help but think about how far he had come himself. After gaining control over electromagnetic force during his "workplace experience," Kaminari realized how overwhelmingly dominant it made him against Tetsutetsu's Quirk.

It was almost tragic—like Marvel's Colossus or Wolverine facing off against Magneto. No matter how durable or regenerative they were, they would still lose outright.

With a soft shhh, the glass doors slid open under Sadako's control. Kaminari turned to see Tetsutetsu stepping inside, his face lighting up when he spotted him.

"Kaminari!"

Tetsutetsu's voice boomed with excitement as he strode over quickly. "What are you doing here?!"

"Haha," Kaminari laughed. "I came to drop off my suit with Dr. Tenma and have some new features added. This 'workplace experience' gave me plenty of new ideas!"

He then smirked, teasing, "But you're a little late. I already got a look at your battle suit, so you missed being the first one to see it."

"Eh, what's that matter?" Tetsutetsu waved it off with a laugh. "I was a little bummed about not being able to see it with you, but hey, you're here now. We can check it out together!"

Despite his words, his eyes instinctively wandered toward the display case where the combat uniform was stored. They sparkled with anticipation as he turned to Dr. Tenma.

"Can I put it on now?"

"Of course," Dr. Tenma said, pointing to a small glass door on the left. "Go ahead and get it, then head to that room to change."

"Awesome! Thank you, Dr. Tenma!" Tetsutetsu cheered, hurrying over to the display case. As the glass cover retracted upward, it revealed the full set of gear inside.

"So it's not just a coat," Kaminari observed as he walked up beside Tetsutetsu. The display included a pristine white suit, a pair of black leather boots, and other accessories.

This is basically a Marine's formal coat.

Kaminari grinned, amused by the sight. "Not bad!"

"Kaminari, wait right here! I'm going to change into this now!"

Grabbing the outfit, Tetsutetsu darted into the changing room without waiting for a reply. The door clicked shut behind him, leaving Kaminari and Dr. Tenma alone in the lab.

"Dr. Tenma, can I ask—where else could I get SIS memory alloy?" Kaminari inquired, crossing his arms thoughtfully.

Dr. Tenma looked at him curiously. "Why are you asking?"

"I was thinking, if I could get another set, I'd like to create a smart battle suit for Tetsutetsu," Kaminari explained, shrugging casually.

Dr. Tenma sighed and shook his head. "That's going to be difficult. First, SIS memory alloy isn't something you can buy, no matter how much money you have. No one is willing to sell it."

"The only way to get it is to 'find' it," he continued. "But that's an incredibly rare occurrence. As I've mentioned before, this material isn't native to Earth. We still don't know how it ended up here in the first place."

Dr. Tenma's voice grew heavier as he shared more. "It's possible that it didn't fall from space in the last few centuries, but was brought to Earth—either deliberately or accidentally—long ago."

"But one thing is certain," he added. "Major countries likely have reserves of SIS memory alloy. Long-established conglomerates may also have small amounts. However, the quantity each possesses, where they store it, and how they use it are all closely guarded secrets."

His gaze turned serious as he looked at Kaminari. "In short, it's extraordinarily rare. For an ordinary individual to own it is almost unheard of—and if they do, it usually doesn't stay in their possession for long."

Kaminari frowned, an uneasy feeling settling over him. Dr. Tenma's implication was clear.

"Are you saying someone might come after my SIS memory alloy?"

Even as the thought crossed his mind, Kaminari's resolve hardened. If anything, this made him more determined to keep his battle suit, not abandon it. His eyes gleamed with quiet confidence.

"Let them try, if they're bold enough," he muttered under his breath, a faint, cold edge to his tone.

The sound of the door opening snapped Kaminari out of his thoughts. Tetsutetsu stepped out of the changing room, his face beaming with excitement.

"Kaminari, look at this!" he exclaimed, his voice brimming with energy. "This combat uniform is incredible!"

He spun slightly, showing off the white coat with the word "Justice" emblazoned across the back. "Man, I can't wait to show Kirishima! He's going to be so jealous!"

Kaminari and Dr. Tenma both took a moment to examine the suit. The design complemented Tetsutetsu's physique perfectly. The white suit gave him a refined, almost elegant appearance, balanced by the rugged confidence of his personality.

Dr. Tenma stepped forward, clearing his throat. "Now, let me go over some details one more time."

He gestured to the outfit as he spoke. "First, the material of the 'Coat of Justice' is AF super-smooth alloy. Its surface is highly resistant to most physical attacks and can even deflect bullets under certain conditions."

"This feature is crucial, so make sure you use it wisely in battle," he added.

"Additionally, the entire combat suit has been enhanced with high-temperature resistance, low-temperature resistance, and insulation properties. While it's not completely immune to these factors, the effects are significant."

"One more thing," Dr. Tenma said, his tone more serious now. "Considering the weakness of your Quirk—metal fatigue—we've developed an iron supplement system for you."

He pointed to Tetsutetsu's coat. "You'll find iron injections in your coat pockets. They'll allow you to replenish iron during combat."

"Got it!" Tetsutetsu rummaged through his coat pockets and pulled out a handful of small, color-coded syringes. He frowned slightly at the sight. "Wait—why are the ones in the left pocket different colors, while the ones in the right pocket are all silver?"

"The left pocket contains hemostatic agents, stimulants, and analgesics. The silver ones in the right pocket are the iron supplements," Dr. Tenma explained.

"Those extra pockets looked empty, so I thought it'd be better to make them practical," he added with a smile. "We even increased their size to hold more items."

Tetsutetsu's grin widened as he listened, his appreciation for the suit growing by the second. He turned to Kaminari, his expression full of gratitude.

"Thanks, Kaminari. If you hadn't introduced me to Dr. Tenma, none of this would've happened!"

What Tetsutetsu didn't realize, however, was that Kaminari's original motivation had less to do with helping and more to do with his own amusement, he just really wanted to see Tetsutetsu wearing a "formal coat."
