"Pork Cutlet Bowl" (カツ丼, Katsudon) is an extra chapter included with Volume 7.
As Saitama is out on a walk he is stopped by two police men on patrol. The curious hero asks why he's being inspected only to find his questions rebuffed and is taken in for questioning. Through further investigation into his background the two lawmen come to the conclusion that Saitama may be the culprit behind a string of assaults that have been occurring around their precinct. Judging by his unemployment, living in a rural abandoned area with blood on his hands makes him only more suspicious. While offered a bowl of pork cutlet by Chief Kuma, they were discussing the Hero Association and Chief Kuma's previous partner, who failed the hero exams and joined the police force instead. He threw himself into his work and was eager to serve but ended up incapacitating while out on patrol. Kuma was distraught to learn such a kind and honest guy kept reciting details of the culprit till he passed out, his final message being one of concern for his commanding officer which only worsened the head of the precincts grief.
While they were still conversing, the real culprit behind the flatfoot effrontery, a threat level demon mysterious being began attacking their station after shedding his delivery man disguise. The monster Surprise-Attack Plum stated his reason for assaulting so many cops stems from a hatred of the law that turned him into a monster. His attacks were all out of revenge for arresting him for drug abuse costing him a job and ruining his familial life. Out of desperation, Chief Kuma calls the Hero Association, with McCoy wanting to dash the dignity of the police, but Saitama quickly snatches and crushes the chief's cellphone before he could plead, clarifying that neither heroes, nor cops do their job when they're beseeching it. Going onto say that the individual on the line was no hero, but Saitama was there and offers to take care of their problem as a repayment for the katsudon.
Outside the police station there are countless bystanders, the local news and a horde of heroes from the Hero Association who were sent by McCoy, after he had leaked the information to the media and sent out every available upper rank hero in order to further disgrace the police force. However before anyone can do anything, a lone police officer steps out of the building, carrying the monster on his back much to everyone's shock and awe as well as McCoy's chagrin. All the news channel present at the scene bustle their way into a police blockade, desperate to know who the mystery officer was that took out the monster. Before anybody could thank him, Saitama had already left the scene content with having helped the police.
When asked by another officer about him, Chief Kuma simply states that initially he was thought to be an unemployed man with no valid address, but later rescinded his opening statement, simply calling him a hero.
