The thirty-seventh chapter closes the alien invasion as the vessel comes down and levels A-City. Sweet Mask and Metal Knight arrive with their own agendas while Saitama walks out of the wreckage to Tatsumaki's fury.
The alien vessel plunges to earth, sending the S-Class defenders scrambling clear and reducing A-City to rubble. Sweet Mask shows up demanding an explanation for the devastation, and when the heroes insist they resolved the crisis, he brands them incompetent, sparking a confrontation with Metal Bat. Metal Knight then materializes to everyone's shock. Pressed by Genos, he admits he came to harvest the alien technology for weapons built, in his words, for the sake of peace.
Superalloy Darkshine discovers aliens who survived the wreck, but Sweet Mask cuts them down without warning, explaining that beings so evil forfeited any right to live and that he simply carried out their execution. Saitama emerges from the debris, startling Tatsumaki and Darkshine alike. Genos hurries over as Saitama recounts his battle with Boros, paying Tatsumaki no attention. Slighted, she berates him, and when Genos snaps back by calling her a brat, she flings him into a building with her mind and threatens a terrified Saitama with the same. Bang defuses the situation, reminding Tatsumaki to carry herself according to her rank.
In the aftermath, the Hero Association headquarters is rebuilt into an iron fortress, and Metal Knight hauls the downed spaceship away to an undisclosed location.
The spaceship crashes and destroys A-City. Sweet Mask insults the S-Class heroes and executes the alien survivors. Metal Knight reveals he wants the alien technology for weapons. Saitama surfaces from the wreckage, and Tatsumaki lashes out at him before Bang intervenes. The Association rebuilds its base as an iron fortress and the ship is relocated.
