"I'm just trying to live my new, peaceful life."

!!! WARNING!!!

[I'm an anime viewer, not a manga reader. I don't know all the details of the rest of the plot, only a small part from spoilers.]

After his flight to the moon, Stanley Snyder returned safely to Earth. However, life has changed so much since he was a stone statue – Xeno no longer strives for absolute power, no longer fights for science against Senku, but works alongside him.

But Stanley is alone. He no longer needs to be a protector; the peaceful times he never expected have arrived. He struggles as he tries to figure out what to do next.
