Heroes vs. Nyan

Heroes vs. Nyan is the battle between several heroes and the Monster Association executive Nyan.

Prelude
Having retrieved Waganma from Child Emperor, the hero support team proceeds on their mission to escort the hostage back to safety. Along the way, they battle more forces from the Monster Association, defeating them easily despite injuries the heroes sustained in their previous battle.

Meanwhile, Nyan, having fled from his separate encounters with Puri-Puri Prisoner and Saitama, arrives on the surface and spots the support team, who likewise notice him.
