Set on recruiting Saitama, Fubuki has Eyelashes sell the Blizzard Group as the biggest and most effective branch of the Hero Association. When Saitama declines yet again, she proposes a contest where the losing side must obey whatever the winners demand. The following day Saitama turns up with Genos, Bang, and King, and puts his name to Fubuki's contract without bothering to read a single condition.

Bang, assuming the challenge is a sparring match, wagers that the losers will join his dojo, but the event is actually a video game, and the Blizzard Group's representative Piko happens to be a former professional player who trounces him. Genos falls next, unable to hold a controller without crushing it, and Saitama loses as well. With King the last one standing, Fubuki gloats that a win is now guaranteed, then watches King flip on his so-called King Engine and clean sweep the match. Over in Y-City, Child Emperor unveils Okame-Chan, a device that gauges a body's strength by weighing muscle, nerve growth, and mass. A monster alarm sends him and several heroes against Jumping Spider, who levels everyone except the boy inventor until Bang shields Red Muffler, Genos tears into the creature, and Saitama lands the killing blow.

Scanning the newcomers afterward, Okame-Chan cracks and reads Saitama's strength as undefined, which Child Emperor misreads as him being pitifully weak; King's reading comes back undefined too. Still crushed by her earlier loss, Fubuki finally rallies and wipes out the monster's scattered spiderlings with telekinesis. The chapter ends with King, Genos, Saitama, and Fubuki eating together at Restaurant Mammoth, the bill settled by Fubuki as her forfeit.
