All in all it's an interesting take on the Set & Osiris myth, with a lot of tie-ins to other parts of Egyptian mythology, and also a sort of isekai, as well. It's a quick read, so if you're curious it's not a major time investment. And short as it is and with the potential for more story, it's complete, so you're not missing anything other than the potential for more (though the spin-off/sequel is on-going). The male character designs are quite beautiful, and I love Set's design, as well as the antagonist's. The way ancient Egypt has been designed is also quite beautiful, and thecostumes are lovely. I'm not the biggest fan of Nephthys, though she gets some depth, especially in the expanded edition of volume 2.

The series has good angst, and the character relationships - particularly between Set and Osiris, and Set and Geb - are quite enjoyable to read about, and Osiris is a fascinating character here. The central plot itself is interesting, if a bit odd.

If you'd like more, I recommend checking out the special edition of volume 2 and the spin-off/sequel series, which goes into more of the story.
