Since its by the same writer who has done pandora hearts, its no surprise that this manga to is in a league of its own. Jun muichizuki implied before that she doesnt really write stories that appeal to the major audience infact she writes stories that appeal to her the most before anything else and that is precisly why pandora hearts was so perfect and its the same with this one. To start with the beginning of the story is rather fast paced but at the same time enticing. There are few predicatable reveals(In comparison to pandora hearts) which were intended ngl( considering the nextreveals). The art is as usual amazing and detailed, and the best is the world building and characters. Its phenomenol with the power system, history and everything connecting to the present.
The best characters are easily vanitas and chloe imo. I do hope the anime does justice to the manga though.
And since the anime is just around the corner, i hope it gets the attention it desrves.
All in all 10/10
