It's not even that explicit despite what the summary suggests. The point of this comedy is to go BORDERLINE, yet it's subdued expectations, I quite like it.
What can i say its a isekai I didn’t start it with any expectations and was not disappointed. I’ll start with the bad, the art can go from fine to bad i enough to distract from the story. The characters aren’t memorable or unique in any way and i would always forget them after a few chapter.
Even with these faults i still enjoyed it. I never found myself extremely bored, i thought the cow was something unique and found myself smiling at some jokes which in the isekai genre happens really rarely since most isekais pander a lot and focus on politics which i really could not care less about.
