While my intent was to read more scifi novels this year I keep getting drawn into mangas before I can get attached to anything I'm reading. The latest of these was The Land of the Lustrous which was a completely random pick.
At 12 volumes the story feels mostly done, though I think there's some wiggle room in there if the authors want to stretch stuff out, but it was a very interesting read. What starts out at a cutesy almost sailor-moon-esq story involving agender (though very feminine) human-looking characters made of various gems quickly tuns into a story about forgetting one's self and one's purpose in the pursuit of goals.
I really enjoyed the series. At first I enjoyed the silliness tinged with dread when the "bad guys" showed up, but the otherwise simple characters got fairly messy as the story progressed and the protagonist gets straight-up ship-of-theseus'd and descends into questioning everything.
Super unique flavor in this one, and they even made an anime of it (albeit 3d anime), though I doubt a second season will be released.
