He won't touch Ta Ying, and Mou Ping eats shit, that's it.
Shimura, the hero of the parallel world, takes an arc and travels through the original world.
The thing is like this. There used to be a big villain with facial features who was planning to cause a big incident. Mr. Saitama, who was involved in the turbulence of time and space, punched him KO. At this time, he didn't have time to harm Shimura Nana's family, so the Shimura Tsuki-kun of this world grew up happily. When he was in his third year of junior high school, when he had just filled out the heroic volunteer list, he time traveled through time.
