This is an extremely difficult series to review, not for any quality reasons it's just *difficult* to review. The MAL page lists it as having 2 volumes and 16 chapters, but lots of manga reading sites list a third volume. This third volume is actually the third volume of a *different* manga series also based on the book in a very FMA/FMAB style way. And just to make things more fun this series is definitely not "On Hiatus" as listed here, but has in fact been discontinued in favour of the new manga that has the suffix "Cycle of the Elixer" (JP: Rinkan no Mahouyaku) asevidenced by it coming out the year after the final volume of this series and still currently releasing.

The other reason it's so difficult is because, well, there's not much here. With only two volumes, the second of which bizarrely taking place before the first, (and that's if the manga site I used didn't mix the two series up), there's not enough here to really get into the weeds of how the characters are, and it frankly jumps about between scenes so fast it seems the series doesn't want to either.

I get it, it's a short manga series meant to advertise the LN, we've seen it before and we've loved many of these, but it just goes too fast. You can tell there's sprinklings of many ideas which will be fleshed out later on, but until they get fleshed out we can't really talk about them. The main characters are competently written and you can tell there's depth to them that hasn't been revealed, the FMC is a bit of a ditz at times but in an endearing way with the MMC being the more stoic reserved type, which is a relationship dynamic we've seen before and it's well done. It's nice to see a male slave fall for a female slave owner (though neither acts like that description might make you think thankfully) and there's a few points where both of them think about this dynamic.

Even the alchemy and magic they use has some depth to it, with her effectively having to be an alchemist in secret and there being all sorts of interesting rules and ideas that you can tell she's just breezing past for the sake of the series pacing.

It's a well made series that got cut short in favour of revamping it for some reason. If you're really interested in the series I'd read this, then begin reading the new one to see if there's any changes but that's honestly the only reason I'd pick this up.
