A brief two-page bonus tucked into the fourth collected volume, this omake catches Saitama sulking over a discount event he let slip past, until a television bulletin about strange sea creatures reroutes his whole afternoon.
Saitama is stewing over a bargain sale he failed to reach the previous day, a missed opportunity advertised on a flyer he happens to be holding. His mood shifts the moment a broadcast interrupts, reporting that a cluster of bizarre creatures known as the Seafolk has surfaced in J-City. Abandoning his earlier regret, he tells Genos the two of them need to sprint toward the trouble as fast as they possibly can.
The flyer reveals the sale Saitama could not attend. A news segment then flags the Seafolk emerging in J-City. Saitama scraps his shopping mindset on the spot and orders an all-out dash to the scene alongside Genos.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....
