My Hero Academia: Thunder God

"Kyoka, if I remember correctly, your battle suit has two speakers on the calves that transmit sound waves from your heartbeat through your Quirk, then amplify it into a sonic boom, right?"

"That's right."

Kyoka nodded curiously and added, "I can also pick up subtle sounds that most people can't hear."

"Oh, right. I almost forgot about your enhanced hearing. That gives me even more ideas," Kaminari said as his eyes lit up. He quickly calmed himself and returned to the main topic.

"Let's start with your battle suit. Why do the speakers have to stay fixed on your legs? Couldn't we place them somewhere else? Or maybe install additional speakers on other parts of your body?"

Kyoka tilted her head, intrigued but slightly puzzled. "I've thought about moving the speakers to my arms, they'd be more flexible there."

"That's a good thought," Kaminari replied with a nod, "but I'm thinking bigger. Instead of just relocating them, why not add more speakers? And of course, we'd improve the ones you already have on your legs."

"For example, we could add micro 'sound ports' to the soles of your feet. With the right training to control soundwave output, you could use them to enhance your mobility. Theoretically, not only could this increase your speed, but it might even let you… fly."

Kaminari leaned back, confident in his idea. After all, Kyoka's soundwaves had enough force to shatter boulders—clearly, they packed plenty of power.

"Fly?!"

Kyoka's eyes widened in shock, and even Tetsutetsu, who was listening on the side, looked astonished.

"Well, maybe not full-on flying," Kyoka said, recovering from her initial surprise, "but it's definitely possible to boost my speed this way!"

"Exactly!" Kaminari said with a grin. "If you direct controlled soundwaves downward, you could use the propulsion to jump higher and run faster!"

"This idea is genius, Kaminari!" Tetsutetsu exclaimed. "If she masters this, it could change everything for her!"

"This is just one possibility," Kaminari continued, "but we don't have to stop there. We could also add sound ports to the back of your hands, arms, legs, or even your back. With this setup, every punch or kick you throw could have a sonic boom effect. It'd be a great way to cover any weaknesses in close combat."

To be honest, Kaminari had borrowed this idea from two Sound Village ninjas, Zaku and Dosu. However, what he was proposing to Jiro was an upgraded, more refined version. After all, as clever as Zaku and Dosu were, their designs were crude— hence why they remained lower-tier ninjas, while Kyoka was aiming for true hero-level gear.

"As for the battle suit design itself," Kaminari said, stretching out his right hand, "let me show you what I had in mind."

Electricity crackled in Kaminari's palm, forming slender threads of golden light that began converging in midair. Within moments, a 3D model of the battle suit floated above his hand, spinning gently as it shimmered with light.

"Whoa!" Kyoka and Tetsutetsu gasped in unison.

"This is insane!" Tetsutetsu exclaimed.

"It's… definitely cool," Kyoka admitted, though she quickly added with a blush, "but don't you think it's a little too revealing?"

The holographic model of the suit was incredibly detailed, showing every contour. The design featured a pair of very short hot pants that barely covered the thighs, paired with high boots that extended up to the mid-thigh. The sleek, tight fit made the suit exude a wild, edgy style, despite leaving only a small strip of skin exposed between the boots and shorts.

"Uh…" Kaminari hesitated. "We can change it to long pants if you'd prefer. Don't focus too much on the appearance for now—let me show you the suit's inner structure."

He couldn't help but admire the "artwork" in his hand. Of course, he wasn't formally trained in costume design, so the appearance was inspired by something from his previous life—the sleek, sexy style of Batgirl's costume.

He had chosen this design because bats, as creatures associated with sound, felt thematically fitting for Kyoka's Quirk.

As Kaminari concentrated, the holographic suit split into layers, revealing the detailed inner components beneath the surface. The breakdown resembled Tony Stark's holographic projections in Iron Man, where a full suit would split apart to display its intricate mechanisms.

"See? The outer layer is just the surface. Now, look at these details," Kaminari said, gesturing toward the hologram.

Tetsutetsu and Kyoka, already overwhelmed by the sci-fi display, leaned closer to examine the layers Kaminari pointed out.

"See these tiny round openings?"

"Yeah," Kyoka said, nodding intently.

"These are the sound ports I mentioned earlier," Kaminari explained. "You'd connect your headphone jacks to a socket near the collar, and the soundwaves could then be released from any of these ports."

He gestured to several larger ports on the hologram. "The ones on your palms, chest, and the soles of your feet are bigger and designed for more powerful sonic booms. We'll call these 'main sound ports.'"

"But," Kaminari continued, "the effectiveness of this suit will depend entirely on your ability to control the soundwaves. You'll need to train extensively to master the volume, direction, and intensity. After all, no matter how advanced the gear is, it's still just a tool, it's up to you to make it work."

He smiled encouragingly, and Kyoka could only nod silently. The sheer depth of thought behind his idea left her at a loss for words.

Is it really possible for me to have such a powerful battle suit? Kyoka wondered, her mind racing.

Before she could say anything, Tetsutetsu raised a sharp question.

"Wait, Kaminari—how would Kyoka control where the soundwaves are released? Wouldn't that be really difficult?"
