It was a crisp afternoon over Musutafu, and Class 1-A was patrolling the city, keeping an eye out for disturbances. The sun glinted off tall buildings, reflecting in the eyes of the young heroes as they walked in small groups. Midoriya adjusted his gloves nervously, scanning the skies, while Bakugo muttered under his breath about the “boring patrol.” Suddenly, the calm was broken. High above, a silver blur cut across the sky, spinning with immense speed. The students froze, their heads snapping upward. “What… is that?” Uraraka gasped, shielding her eyes. “It’s moving way too fast to be a drone!” Kaminari added, his hands crackling with electricity in response to the sudden tension.

The object gleamed in the sunlight as it twisted gracefully midair before landing softly on a rooftop nearby. It was a hammer—ancient, crackling faintly with energy. A small, golden lightning emblem glowed on its head. “Is that… a quirk?” Todoroki murmured, his expression calm but curious. “No way… It’s Mjölnir!” Bakugo shouted, eyes wide. “I’ve only seen that in myths!”

The hammer didn’t belong to anyone in sight. It floated slightly, hovering above the rooftop, vibrating with an almost sentient power. Class 1-A exchanged astonished glances, unsure of what to do. Kirishima took a cautious step forward. “Should we… touch it?”

“Don’t! We have no idea what kind of power that thing has!” Mina warned, waving her hands. Meanwhile, far above the city, a boy of normal human size—{{user}}—stood on a distant rooftop, his hand raised and eyes focused. With a swift flick, he sent Mjölnir soaring into the air again, testing its trajectory and his control over it. Lightning danced across his grip as the hammer obeyed him effortlessly.

“I’ve never seen anyone control something like that without a quirk license!” Yaoyorozu added, jaw tight with curiosity. The students watched, mesmerized, as Mjölnir spun and twirled, returning to {{user}}’s hand as if pulled by an invisible force. None of them realized the boy wasn’t a villain, just a young demi-god, son of Thor, testing the power gifted to him—a power far beyond any normal human, even without the size or strength of a fully grown demigod.

Midoriya’s eyes widened. “That… that’s incredible…” Bakugo gritted his teeth, staring with a mix of irritation and awe. “Who the hell is this kid…?” And from the shadows of the rooftops, {{user}} remained silent, continuing his training with Mjölnir, the hammer of the thunder god, completely unaware of the young heroes watching in wonder below.
