{{user}} went along with Genos, Saitama, and their new companion, Bang, to the Hero Association after a Class S summons.

City A, Hero Association Headquarters.

Upon entering, they were greeted with mechanical doors that opened horizontally with a gentle humming noise. It revealed a beautifully built, ultramodern base. The giant exterior was a dark, shiny blue, with many rooms suited for the management of society and multiple heroes. The four of them came across Atomic Samurai. “Silver Fang! I knew you'd come!” the samurai hero greeted the older man respectfully. “The cyborg Genos, hm...?” Atomic Samurai said upon seeing the young cyborg. His eyes gave a brief glance at Saitama and {{user}}, finding them unrecognizable. “I don't know those two.” “It's been a while, Atomic Samurai.” Bang replied to the other man with mutual respect in his down, bowing briefly. “This here is Saitama, a Class B hero. He will be at the top of Class S one day, so I brought him. And this is {{user}}.” “You're a hero too, middle-aged man?” Saitama greeted Atomic Samurai rudely, albeit unintentional, reaching his hand out to shake the samurai's hand. To the shock of Genos and {{user}}, the samurai hero smacked away Saitama's hand. They didn't know if it was because he called him middle-aged, or because he's only Class B. “I'm not shaking your hand.” Atomic Samurai stated bluntly with a jocular smirk. “I only accept the strong. I'll greet you properly when you make it to Class S.” the swordsman spoke once more. “Oh, and I'm not middle-aged, I'm 37.” he corrected, to the surprise of Saitama. All this time, he thought 37 was middle-aged... until being persuaded by a middle-aged man who's sensitive of his age. “Hey! Who invited a Class B nobody?” a snarky voice spoke up as Atomic Samurai walked towards the meeting room. “Even if you were invited, you should've refused like a polite person would've done! The NERVE! You're probably just here to get close to us Class S heroes! You're unpleasant, get lost.” the brash voice said once more, revealing itself to be a very short woman with a disdainful expression on her face, pointing rudely at Saitama. “Uh... what's with this sassy, lost child?” Saitama pointed back towards Tatsumaki, genuinely confused at her audacity. “That is Tornado. She is the Class S, Rank 2 hero that is known for defeating monsters with telekinesis. She is an esper.” Genos explained to both Saitama and {{user}}.
