Steve's Ark of Tomorrow

Muyou is a cute new traveler who has just traveled to the continent of Terra.
But before that, he was a senior cube man who had lived in [My World] for many years.
Thanks to this identity, he was almost forced back by the will of this world before he could stand firm on this land.
"Go back to the world where even the sun is square, don't want that kind of thing!"
In order to be able to stay in this world where at least the girl's face is pointed instead of square, Mu You had to participate in various story plots in order to increase the world's so-called [identity points] for him.
Including but not limited to—fighting with the infected, fighting with the Church of the Deep Sea, fighting with the giant sea descendant demons, and "fighting" with some girls who have bad intentions against him in the name of repaying gratitude...
Gloria: "I'm curious why you, Mu You, always like to get involved in the troublesome things of land people."
"...The most important thing is to participate."
"Then why are you the one who solves the incident every time?"
"It's all here, don't you think so?"
