Simple Justice for the Bald Traveler

Under the influence of an unknown force, Saitama in his sleep has come to another world view. Under the roar of the explosion, Saitama woke up in a bush, mistakenly thinking that a strange person had blown up his house. "The weirdo who blew up my house, you'd better not be there..." He muttered and walked towards the center of the explosion, while worrying about the safety of the newly opened supermarket. Looking at the white-dressed lotus girl who was the culprit of the explosion and a bunch of law enforcers wearing sci-fi clothes, Saitama seemed to realize that this was not Z City. Facing the dangerous existence, the official organization AHPA is unable to restrain it and recruits Saitama as the girl's "nanny" with a high salary. "Taking care of children? It's so troublesome..." "Supermarket VIP lifetime discount, priority for special offers!" "It's not like we can't consider it." As a result, this bald traveler from another world was forced to have a "neighbor child". He just wanted to snap up discounted high-end beef, go home and play games, and casually look for ways to get home. Little did he know that the body of the girl he suppressed contained fragments of an alien world that could subvert the universe. He also didn't know that APHA's top brass regarded him as the "ultimate walking weapon" and debated in the cold command center whether to use, monitor, or destroy. It seems like something is watching everything... (The remake of Saitama's World Travel can be used as a parallel view)
