### Summary
Prompted by Genos, Saitama finally agrees to seek official recognition from the Hero Association, arriving just as the organization's elite S-Class heroes are being assembled for an emergency briefing. The meeting introduces a bizarre gallery of the world's most powerful protectors, most notably the flamboyant Puri-Puri Prisoner, a hero whose immense strength is matched only by his unsettling libido, for which he is serving a 10,000-year prison sentence. While the top-ranked heroes grapple with dire threats to humanity, Saitama and Genos remain completely unaware, focused instead on the mundane bureaucracy of their hero registration exam.
