Spectators at a dining table engage in Hero Gambling, betting on the responding heroes as Papillon 800 requests assistance upon seeing the monster.

As he blacks out, he recalls Mr. McCoy’s attempts to coerce him into hero gambling, including threats to his hospitalized mother.
Waking up, he reports the “crazy strong monster” to HQ while McCoy and others watch. Despite his injuries, he continues the fight, recalling Mumen Rider’s determination against the Deep Sea King.
Saitama interrupts the rigged match by defeating the monster, shocking everyone present, including Pavilion 800.
