It is clearly a parody anime. If you enjoyed Overlord and Tensura, you'll like this. It plays off of the same sort of themes as both of these stories, with its own twist. This could honestly even pass for an 'abridged' version of either Overlord or Slime, it's so similar. But it builds to the flaws of its inspiration. It's trying to be funny, slice of life, but in the same sort of 'what if'-isms that I'm sure you asked yourself while watching or reading either Overlord or Slime. Don't expect any plot other than 'isekai world building' with some moderately funny jokes
