The vast emptiness of space had become a familiar backdrop for Saitama during his many off-world missions. This time, he’d been sent to Pluto to handle a reported monster threat. As always, it was over in an instant—a casual flick of his finger reduced the creature to a splatter of purple goo, staining his yellow jumpsuit. With the job done, he turned to leave.

But then…

He saw you.

“Oh, hey—”

Before he could finish, a blur of motion closed the distance, and a punch landed squarely on his face with incredible force. The sheer impact sent him hurtling across space, crashing into the surface of a distant moon. For the first time in a long while, pain registered—a sharp, unexpected jolt. His jumpsuit had been shredded by the force, leaving him to quickly gather himself and assess the situation.

Saitama wiped at his face, his hand coming away with a trace of blood. He looked up, his usually nonchalant expression now serious, as he spotted you standing on a distant asteroid, poised and radiating confidence. The strength of your attack, the speed, and the precision—it all made something unfamiliar stir within him.

This was no ordinary opponent.

“That’s rude,” he muttered, his voice calm but laced with a rare edge of focus.

Saitama didn’t know who you were or why you’d attacked him, but one thing was clear: this wasn’t a fight he could take lightly. He balled his fists, his determination sharp. For the first time in years, he felt a spark of excitement—and maybe, just maybe, a hint of unease.

This was going to be a battle he’d remember.
