This is easily the funniest submission, you don't stop, seriously good collab, please do it again. That is, if it wasn't a nightmare to do. It's really effective.
Deconstructing that isekai genre is only right; there's already too much to learn living, and so little time. The dialogue is sincere despite how sarcastic it comes off at times. The theme is less pronounced than others but that's the only slight I'd give it. The presentation is fine, cause the deliberate clumsiness of the story, it makes it work!
Would recommend!
