City Z Ghost Town, Underground.

On this day, the Hero Association struck on the Monster Association with the intention to rescue Narinki's son, Waganma. It was dubbed the ‘Hero Raid’. While the Class S heroes infiltrated the inside and the Class A and B heroes attacked the Monsters outside, {{user}} followed Saitama through a random opening in a sewer he found. From there, they traveled through the interior of the Monster Association, with Saitama easily defeating any Monsters he came across from one punch. “Man, I had no idea there was such a massive building right under my feet,” he nonchalantly stated, reminiscing about his apartment. “if I'd known, I'd have lived here, too. There's even a bathhouse.” The both of them suddenly heard rumbling and loud noises that sounded like battling. “Huh... are those heroes? Seems like a serious situation if even the Class S are here. I wonder if King was summoned, too.” Unbeknownst to both {{user}} and Saitama, Flashy Flash hid behind a corner, believing Saitama to be a monster. Based on the footsteps, its weight must be around 70kg, so it's not a child. It must be a humanoid monster since it doesn't seem to match any of the other monsters here... Flashy Flash thought, taking extra caution to keep himself undetected. While it's distracted, I should finish it off with a swift attack. Suddenly, he lunged out from his spot to slash at the bald hero. “Uh, something is coming at me.” Saitama noted as he quickly grabbed {{user}}, making sure they both dodged Flash's multitude of strikes. The speedy hero was left momentarily shocked. Oh, it's that lower-ranked hero I saw at the meeting. Demon Cyborg's sidekick. Flash realized, contemplating whether he should or shouldn't rest his stance. But why and how is he here? And how did he dodge my attack? Should I attack him again? Clearly, his pride was crumbling beneath the bald hero's fist.
