However, he stays outside in the blizzard for too long and freezes, losing his balance and crashing through a window. The heroes tie him up, but Sonic still plans to kill Saitama.

Sonic easily escapes the rope and tries to attack Saitama from under the floorboards, but is stopped by Genos, and their encounter destroys the room.

The heroes grab a flashlight and head to the den, finding the room destroyed and Zombieman unconscious. The group finds that they all have good alibis, and assume the monster must be responsible.

The group is relieved at the conclusion.
