I started out playing Saitama, and now I'm One-Punch Man?

Qi Yu transmigrated to Earth and, due to his congenital baldness, unexpectedly awakened a system that allowed him to impersonate Saitama from One-Punch Man. The closer his true form resembled Saitama, the higher his impersonation rate. He lifted his wig, revealing a shiny bald head. [Imitation Rate: 31%] He shaved off all the hair around his head. [Imitation Rate: 33%] He trained according to Saitama's methods. [Imitation Rate: 34%] He donned Saitama's battle suit. [Imitation Rate: 41%] He killed monsters. [Imitation Rate: 43%] As his impersonation rate increased, Qi Yu defeated any monster with a single punch. His battle videos were uploaded to the internet, instantly igniting the online community. "Is he that awesome??? One punch and he's done it???" "One punch!!! Another punch!! No matter how powerful the enemy, he can take them down with one punch!!" "Holy crap!!! Could this be the legendary One-Punch Man???"
