"I forgot who I was, but my muscles didn't forget how to kill people."
He is an ordinary person who has lost his memory and just wants to live a peaceful life, but there are always blind gangsters, killers, and plutocrats bumping into his fists.
He doesn't know the moves, but his body can use the most ruthless killing skills; he doesn't want to cause trouble, but his instinct makes corpses everywhere where he passes.
When the cold female instructor came to him and told him a code name - "King of Hell", he realized that what he had lost was not his memory, but the fear of the entire world!
This book has no system and no special powers. It relies solely on the well-tempered body and the bone-deep killing instinct to experience the most realistic "passive" killing through the entire scene!
