The story resembles that of a generic isekai. The art is meh. The characters are nondescript and flat (in more than one way).

Therefore I recommend it!

...Because it's very clearly a self-aware parody.

None of the characters have any actual names - they're that nondescript. The hero is so OP and bland that even the girls make fun of him... behind his back of course. In front of him, they figuratively suck his D. Not literally of course, because the hero of a generic isekai is usually chaste.

In any case, its chapters are so short that you won't waste much time by choosing to read it. That being said, you also won't miss much by completely ignoring its existence.

TL;DR: eh, it's something.
