One Punch Man Manga Chapter 45

Fubuki reveals she intentionally remains in B-Class to dominate lower-ranked heroes, convinced she can never surpass her sister Tatsumaki or overcome Sweet Mask, who prevents others from reaching S-Class. Meanwhile, Sweet Mask easily defeats the monster Suppon, boosting his popularity.

At Saitama’s apartment, Fubuki compares him to Sweet Mask and Tatsumaki—acknowledging his strength but underestimating his threat. King’s sudden arrival shocks her and makes her reconsider siding with Saitama.

At the Hero Association, Saitama and Genos receive their hero names: Caped Baldy and Demon Cyborg. Attention briefly shifts from Garou’s rampage to the naming process. Elsewhere, Garou defeats Tanktop Vegetarian but remains unsatisfied, continuing his relentless hero hunt in search of stronger opponents.
