Deep within Asgard

Frigga's Chambers

Frigga, Queen of Asgard, stood silently by the window, worry written all over her face.

Her eyes flickered with surprise when she saw Thor walk in with Jiro.

"Mother!" Thor strode forward. "I'm back. Loki's been taken care of."

Frigga let out a breath of relief, then turned her gaze to Jiro. "And this is…?"

"Jiro, from Midgard," Thor introduced. "But he's not your average human. His strength… actually surpasses mine."

Frigga raised her eyebrows slightly, giving Jiro a thoughtful once-over.

After a few seconds, she smiled warmly. "Welcome, Jiro. Thor rarely speaks so highly of anyone—you must be something special."

Jiro gave a polite nod. "Your Majesty, I came to Asgard to learn your science and magic."

Frigga seemed intrigued. "Asgard holds vast knowledge, but not everyone can comprehend it."

"I'd like to give it a shot," Jiro replied calmly.

Frigga chuckled. "Alright. I'll have someone take you to the library and the workshop. But before that…"

She turned to Thor. "How's your father?"

Thor's expression darkened a bit. "He's still in the Odinsleep, but Loki's schemes have been stopped, and the crisis with the Bifrost is over. He should wake up soon."

Frigga nodded, then looked back at Jiro. "If you're serious about learning Asgardian knowledge, a good place to start might be the theory of the World Tree."

"The World Tree?" Jiro raised an eyebrow.

"It's the foundation of the Nine Realms and the source of all our magic," Frigga explained.

"If you can understand it, you'll understand the very core of Asgard."

A spark of interest flashed in Jiro's eyes. "Sounds exactly like what I'm looking for."

Asgard Library

The library was a grand golden hall, its towering bookshelves stacked with ancient scrolls and metallic tomes.

Standing in the center, Jiro looked up. His super vision allowed him to instantly scan the entire library's contents.

"This place holds knowledge on the history, magic, science, and warfare of the Nine Realms…"

Thor beamed with pride. "Even I haven't read a tenth of it."

Jiro walked up to one of the shelves and casually pulled out a metal book.

As his fingers brushed the pages, his super brain kicked into high gear, rapidly decoding the symbols and text.

"Your rune system is really fascinating," he murmured. "They're not just letters—they carry power."

Thor looked surprised. "You can read that?"

Jiro didn't answer—he just kept flipping through the book.

His reading speed was off the charts. One glance at a page and he'd already understood and memorized everything on it.

A few minutes later, he closed the book, eyes gleaming with thought. "So that's it. Asgardian magic is basically another way to tap into cosmic energy."

Thor scratched his head. "Uh… yeah, kinda?"

Jiro set the book down and turned to Thor. "Take me to your tech workshop. I want to see how you forge things."

Thor grinned. "No problem! You're in luck—our master blacksmith, Eitri, just finished making a new batch of weapons!"

Nidavellir

Realm of the Dwarves

Via the Bifrost, Jiro and Thor arrived at the dwarven forge realm.

Molten lava roared around them. Massive rings circled a dying star, which the dwarves used as a power source to forge legendary weapons.

"Thor!"

A booming voice rang out. It was Eitri, the Dwarf King. "What are you doing here? And who's this stranger?"

"This is Jiro, from Midgard," Thor said. "He's really interested in your forging techniques."

Eitri looked Jiro up and down, his voice gruff. "A mortal? You think he can handle the heat here?"

Jiro just smiled and walked straight up to the edge of the forge.

The intense heat didn't faze him one bit. Not even a thread on his clothes was singed.

Eitri narrowed his eyes. "Interesting…"

Jiro watched the dwarves work. His super vision let him clearly see every hammer strike and the exact timing of every quench.

His brain processed everything at lightning speed. In no time, he had figured out how it all worked.

"Your forging is more than just brute force," he said. "You've infused it with the energy pathways of the World Tree. That's how you make enchanted weapons."

Eitri stared in disbelief. "How the hell do you know that?"

Jiro didn't explain. Instead, he walked over to a chunk of unshaped Uru metal. "Mind if I give it a try?"

Eitri hesitated, then finally nodded. "Alright. Just don't waste the material."

Jiro picked up a forging hammer, a golden glint flashing in his eyes.

At first, his movements were a bit stiff, but he quickly found his rhythm.

Even more impressive, every strike he made was clean and precise—perfectly controlled in both force and angle.

Clang! Clang! Clang!

Under his hammer, the metal began to take shape, and faint energy started to swirl within it.

Eitri was dumbfounded. "No way… Even Asgardians need decades to master that level of skill!"

Thor looked just as shocked. "Jiro, who are you really?"

Jiro stopped hammering and glanced at the forming blade in his hand. He said casually, "Just a guy who wants to learn."

Right then, a beam of golden light suddenly shot down from the sky!

Thor's head snapped up. "It's Father—he's awake!"

Jiro set the hammer down and looked to the sky. "Looks like Odin wants to meet me."

Throne Room, Asgard Palace

Odin sat tall on his throne, his one eye fixed on Jiro as he entered.

His gaze was deep and commanding, like he could see straight through you.

"A visitor from Midgard," Odin said slowly.

"Your power… is quite unique."

Jiro met his eyes without flinching. "My power belongs to me."

Odin was silent for a moment before saying, "Thor told me you saved Asgard. That you stopped Loki's mad plan."

"For that, I thank you."

Jiro nodded. "I just did what needed to be done."

"But you didn't stay in Asgard just to 'learn,' did you?" Odin's gaze sharpened.

Jiro didn't dodge the question. "Knowledge is power. And power helps me take control of my own fate."

Odin studied him for a long moment before finally leaning back on his throne. "Alright. You may stay and study the knowledge of Asgard. But remember…"

His voice lowered. "Some secrets are not meant for mortals."

Jiro smiled faintly. "Don't worry. I'm not into secrets. I'm after truth."

A small smirk played on Odin's lips. "Interesting answer."

Jiro spent his days racing through Asgard's libraries, workshops, and even magical halls, soaking up knowledge like a sponge.

He studied rune magic, learned how the energy of the World Tree flowed, and even picked up basic teleportation spells.

Everything he saw, he memorized. He could recall it all anytime.

Meanwhile, he sparred with Thor a few times.

Their fights shook the whole palace—thunder and heat vision clashing in a dazzling display that left Asgardian warriors stunned.

Frigga would sometimes personally teach him magic techniques, while the dwarf king Eitri constantly praised his forging talent.

Loki was locked up in the dungeons, but Jiro could still feel it—his schemes weren't over.

Morning.

Jiro stood at the highest point of the palace, looking down over the Nine Realms.

"I've learned enough," he murmured. "Time to head back to Earth."

Thor stepped up beside him and handed him a cup of mead. "Heading out?"

Jiro took it and drank in one go. "Yeah. Got things to deal with back home."

Thor grinned. "Next time you come, bring some good Midgard booze."

Jiro chuckled. "Deal."

The light of the Bifrost flared once again, and his figure vanished into the beam.

When he opened his eyes, he was standing on the streets of New York.

Dark clouds hung low in the sky. In the distance—sirens. Explosions.

Jiro looked up toward Stark Tower, smirking.

"Looks like I got back just in time."
