The Strong Among the Ordinary

The Strong Among the Ordinary (強一般人, Kyō Ippanjin) is an extra chapter included with Volume 24.

Summary
A monster named Dark introduces himself. He wishes to be the strongest monster in history and wants to make a name for himself by assassinating an S-Class hero as his start. Dark arrives at a venue where an S-Class hero is having a fan meetup, and plans on disguising himself as one of the fans and striking down the S-Class hero by surprise. Upon arriving, he is asked to get in line among the fans in order to meet the hero. As he opposes, a fan approaches and grabs his arm, with him being unable to break free. Dark is amazed by the fan's strength, who he suspects to be a hero slipped in as a normal human. Another one then comes and easily restrains him, much to his shock.

As they are revealed to be Superalloy Darkshine's ardent fans, all of them surround Dark and begin stripping his and their own clothes, exposing their extreme muscular bodies, even more muscular than he himself. After the meeting with Darkshine and seeing the demonstration of the hero's strength, Dark is discouraged and flees as Saitama runs into him and asks him if he is fine.
