From the picture I was thinking it was the guy who did Sunred and Pudding Empire (which would be great too), but this is still pretty funny. Very One Piece art, but pure comedy.
Should this be an Isekai or well a person from another world comes from our world so technically it isn't isekai, whats the Japanese for from this world?
@greatninja3 Isekai just means Another World.
Any sort of transportation from one world to another still fits the isekai genre. Yeah, this is an isekai, just like The Devil is a Part Timer is.
They're just doing nothing on an island, the characters can be changed out with literally anyone else and the story would somewhat be the same. Its getting kind of boring.
