It is bad, the story is that of any trashy isekai anime, same goes for the character designs and the animation is bad too, however, once I got past episode 1, I was pleasantly surprised. It is obvious they were on a budget, but they almost always manage to stay within their means, avoiding flashy stuff and using many tricks to make fights easier to animate, without resorting to ugly cg. The result isn't a masterpiece but a respectable anime with good timings, good flow, that is overall enjoyable (except for episode 1, that's very trash, I don't know what they were thinking).
