It's not bad. If you want an isekai harem with really hot girls of different species and some ecchi/romance mixed in then this show is fine. The fighting is pretty meh and the story is filled with a lot of flaws and plot holes. The show is extremely predictable, you already know what's going to happen the majority of the show before you even watch it cause the synopsis tells you everything. He's going to go around collecting the rings aka go find the 4 other hot girls to marry then fight to save the world from the Abyss King. And I'm sure you can guesshow it ends.

It's only worth watching if you're in it for the lewd waifus and not the story. The show does have romance progression but it doesn't feel satisfying. Too many times things start to get good only for your usual interruptions to ruin the moment. Still much better than your common blue balls romance shows where you have to wait till the final episode to see them potentially kiss let alone confess.

Don't bother watching unless you're only here for the waifus.
