Genos and Saitama are at their apartment discussing their rankings. Saitama was promoted to C-Class Rank 342, while Genos was ranked 6th in a hero popularity poll, much to Saitama's shock. Outside the Earth a giant meteor changed track and was heading straight towards Z-City. Genos is called by the Hero Association to come to the Z-City's Hero Association Branch, where he meets S-Class hero Bang.
Bang inform Genos that everyone from the Hero Association evacuated, as all S-Class heroes were called, however they are the only two remaining. Genos wonders why, but Bang explains the reason why they were called was because a Dragon-level meteor that was not just going to destroy Z-City, but damage the cities around it. Bang informs Genos that half an hour ago, they tried to estimate the point of impact and will announce an evacuation notice. Despite all that, Bang shows a fearless expression of the coming panic. As the alarms go off Bang tries to show his power, but Genos has already left.
Genos is seen speeding over rooftops and notices the citizens have already given up on their lives and activates his suitcase that reviles his new Arms Mode. As he prepares himself, Metal Knight flies by and lands on a rooftop, while Genos wonders if Metal Knight came to risk his life for the city, Metal Knight simply explains that it's just a suit and he's in a safe distance. Metal Knight simply came to test the new missiles he developed, then fires missiles from his back, with Genos complaining to himself that he can't fire his beam.
The missiles hit the meteor and Genos is amazed with the destructive power of those missiles, but that could not stop the meteor. Genos' mind starts racing about how to destroy the meteor when Bang appears, but can not do anything as he is a close-range combatant. Genos thinks of Saitama and comes back to his senses. He opens up his chest to reveal his Power Core which he attaches directly into the shoulder of his left arm. He tells Bang to get down and then launches a massive attack at the meteor. His attack does nothing to the meteor, unfortunately and Genos runs out of power and collapses on the roof.
Suddenly Saitama arrives and tells Bang to take care of Genos, as he launches himself towards the meteor, destroying the building. As Saitama is flying he punches himself through the meteor, completely destroying it. The pieces of the meteor then start to rain on Z-City, destroying buildings, including the one Genos and Bang are on. Saitama then lands, looks around, and nonchalantly states that the job is settled. It took Saitama 8 seconds to destroy the meteor.
Three days after the meteor incident the heroes rose in rankings. Genos was promoted to S-Class Rank 16, Bofoi was promoted to S-Class Rank 6, while Saitama was promoted from C-Class Rank 342 to Rank 5. Even though Z-City was severely destroyed, no one died in the process.
