What a weird show.... Seriously, it refuses to adhere to things such as "logic" or "common sense", containing some baffling decisions, such as having its worse looking episode be its first and making its final episode end with a fucking slideshow. Seriously, what the hell.
The best way I can describe this anime is "disappointing". It's not a bad story, the voice actors aren't bad, the animation (generally) isn't all that terrible, but its an extremely poor adaptation.

Let's first talk about the art. So many aspects of it look so weird, for instance, it looks like someone poured gasoline in everyone's hair", sometimes everyone just freezes for a bit while we wait for someone to just finish talking, the 3D looks absolutely terrible, it constantly reuses stuff, it often looks jank, the colors often seem off, the lip syncing is off sometimes, etc., it's not bad looking, but it has so many small little things that constantly pick away at its overall quality that it just left me with an overall negative impression. The sound design has a similar problem with it's just generally unpolished, which left me thinking of it as amateurish. Sometimes it's perfectly fine, however, other times its bafflingly out of sync with the action on screen (there were some scene where I was seriously wondering how they let sound work this bad pass), uses sounds that just feel completely off or uses repetitive sound effects (including a few stock ones that felt really out of place). Again, same story with the voice acting, it generally isn't bad at all (actually, it's probably the most consistent part of the show), however, there are a few instances where it sounds stiff or off.
The story ends up being a 1 to 1 recreation of A Returner's Magic Should Be Special's, so while it's not bad, it ruins its source material by making the pacing so much more terrible than the original. Everything is left in, including stuff that clearly doesn't work outside the comic format like there being a pause everything Desir uses magic analysis so we can see his eye light up and the action being cut up by dialogue (nothing is allowed to happen as long as someone is talking, this is true for basically every single scene). These issues make the show feel unbearably slow at times, with some moments feeling as if they twice as long as they really needed to be. Nothing being cut (from a story that was already somewhat slow at times to begin with) does mean the story doesn't feel rushed and characters get properly developed, yes, however, it's really not worth it when it means the end result ends up being this slow. Words cannot do justice to how mind numbing some scenes are, I couldn't believe the fact no one brought up, at any point throughout the process of making this show, how slow some of the scenes were.

Mid 5. All things considered, it's not terrible, like the title of this review says, it's disappointing, but it's not terrible thanks to the base it uses. If you should take 1 thing away from this review it's this : don't watch this. Just read the web comic instead.
