If you ever asked yourself how can a good idea turn to a mediocre work, than this manga will give you the answer. First of all, this manga clearly failed why it got axed. Also it is to mention that it started at the same time (1-2 weeks apart) with Undead Unluck and Mashle, so I will a bit compare these 2 with this one to get a more accurate picture why it failed and got lost in the mediocre world.

Story 4/10
The story started interesting. A well-skilled protagonist, a witch which has to be saved from her curse, so they go on a journey full of monsters, mysteries and interesting world, kinda like Shingeki no Kyojin. However, all that could have been but never did. Shortly after they put their first step outside the world, they immediatly lose against a monster and a short training arc begins and just after that we get our first "rivals". What does that mean? The mangaka just skipped all the world building and adventure vibes, to get us as fast as he can to action, which was immensely underwhelming. And just after the first "rivals" you get (almost) the same twice again...
I really appricated the base aspect of the story and the mysteries behind them, but it got totally sacrifced for the sake of poor, repeating battles. On the other hand the readers of jump get 2 mangas (undead unluck and mashle) which had a much weaker base story but have an incredible and developing action (not to mention that after they started to work on their world building, even the story got outpaced).

Art 4/10
Some of you may think: "Action? Nice! That is what I want!". Of course you get action, but it's so damn unsatisfying due to this weak art style you won't really enjoy it. All the characters look also very similar, while you get maybe 2 or at most 3 monsters (even it is supposed to be, that the world is full of them... So where are they?). So after a little bit you will think even if a new character comes, you saw that and due to the hiatus of the monster you just get the same drawn characters again and again...
However, even if the story and the characterdesigns are repeating, the art itself was not a catastrophe, mediocre for sure, but not bad.
While 2 other competitors (you know which 2 I mean ;) ) have an amazing artwork, which even get better and better...

Character 3/10
Do you remember when I mentioned at the beginning we have a well-skilled protagonist and a cursed witch? Yeah, forget them just like the author did, and make them to some total average boring characters... After a 2-3 chapters, all what was interesting in our 2 mains get totally lost... The third one, which I didn't mention yet, got so strongly unnecessary that you would forget her, if she wouldn't be on every page to standing in the background doing nothing! All the "rivals" are almost the same as our protagonists, this is also the reason why I don't call them villians, because they have similar ideals than our characters. So yeah, this work even miss a true villian (because, as mentioned, you can't even find any monsters).
So you get boring / empty characters which are also copy pasted, because to think of a new character is way too hard... And then jump has mangas where you get a multifaceted characterpool...

Enjoyment 4/10
I had a bit of fun with this work, mostly because I hoped for more/better. More worldbuilding, more tension due to the deadly curse or monsters, more mysteries, better adventures and actions. But at the end it was just disappointing... Some parts was nice, so I wouldn't say it was a total waste of time, but you can spend it better.

Overall 4/10
If this manga maybe started later, where other works ended (like Demon Slayer or The Promised Neverland), and hadn't compete against 2 very strong uprising works, than it may had more time for a better world building, more adventure and mysteries. Especially, because it got replaced with mangas which in my opinion (at least currently) not even as good as this (failed) one. So it's a bit sad, but it had its chance to be much better.
So I would say, don't read it, you have better options. And at the same time I hope that the author comes up with an even better idea (maybe next time with someone else on the art), because I see potential for a good work with a bit more of luck and patience.
