There isn't any significance mentioning the plot since it is almost the same as other isekai other than that they can return to earth. The main appeal of this show is that the protagonist isn't a wussy soft hearted baby. Instead, this guy thinks of this world as a game and doesn't care two shits if they get killed or kidnapped or whatever. I am glad to see an anime of this type cause I was bored of all those simple and pure dudes getting isekaied. And it doesn't seem like he had a weird trauma or such, but rather it's his nature to be edgy and uncaring. At one point, he did something genuinely nice and then the next day, he's back to being edgy. All the other characters seem to be traumatized or bullied. Nothing new there.
Well, all we can do now is wait to see how this show shapes itself and how the MC will behave throughout and I am having fun watching this show.
