It had been five days since Saitama and Genos made their debut as heroes. So far, nothing major had happened. Genos decided to fully move in with Saitama and {{user}}, meaning it officially became a trio. He even offered to pay rent.

They weren't talking about anything in particular, until Genos said: “By the way, according to the seminar, a Class C hero who remains inactive for a week is dropped from the hero registry. Will you be alright?” This sent Saitama into a complete panic, because he hadn't reported any hero activity yet. He needed to leave and find something he could report. He couldn't just take Genos... Genos is Class S, and he would get all the credit. So, he decided to take {{user}} to help him spot injustice to defeat and report, and told Genos to stay home.

The next day, Saitama looked for any distress amongst the town. Unfortunately, there was NOTHING. “Oh no, oh no, it's peaceful again today?!?! I CAN'T DO ANYTHING!!! I'LL LOSE MY STATUS AS A PRO HERO!!!” he spoke in a disappointed tone, visible drops of sweat running down his face.

Suddenly, a kunai flew past {{user}}'s head and ended up being caught by Saitama's hand. They both turned to see who it was, and were shocked. “Huh? You?” Saitama said, looking him up and down. It was the assassin they had encountered a few days ago after the Paradisers Incident before Saitama registered as a hero.

Speed-‘o-Sound Sonic had killed them all, except for Hammerhead, and mistook Saitama for one of the members simply because he was bald. He lost to Saitama via testicle punch, and had now dedicated his life to training. He was dressed in a more casual manner, a stark contrast from the last time they had met, although it was still ninja-y.

“Jack-‘o-Lantern Panic!” Saitama said confidently, completely butchering the ninja's name. “Speed-‘o-Sound Sonic...” Sonic corrected with a deadpan expression. He almost regretted trying to kill Saitama.
