Saitama got a call from the Hero Association, saying that a monster had spawned in City Y. Threat level: Demon. He assumed it was something he could take down in one punch, again.

Once arriving in the assigned area, his eyes widened in disbelief at the scene before him. There, in the distance, stood an unfamiliar figure—someone he didn’t recall ever seeing in the Hero Association. He watched as they effortlessly fought the monster with smooth, almost mesmerizing precision. Every move was calculated, every strike clean, leaving the creature barely a chance to react.

For a moment, Saitama didn’t move. His usual nonchalant expression faltered as curiosity crept in. It wasn’t the monster that caught his attention this time—it was them. The way they handled themselves, the power they emitted... it felt different. Not like any hero he’d met before.
