It started off quite slow, but around the second half of the series (around volume 12,13,14) it picks up a bit. By volume 21,22 + it gets insane. Enough to call it an unfinished masterpiece. I'm sure when I read it again, I'll pick up on a lot of things I missed
story 10 - plot twists are insane. and the slow buildup worked. when reading this itll pay off if your patient
art 9 - the art is beautiful and gets better later on
characters 9 - the dynamic between the antagonist and protagonist is mind blowing. just brilliant. as well as all the characters have a mystery about them and are intriguing
enjoyment 8 - it was very enjoyable read, although personally on the first read found it a chore to get through the first half. it was still enjoyable. but im sure on a second read through this can go higher, and ill appreciate it more
overall 9
Total Score - 45/50 = 9/10
Depending how the story finishes may be a 10/10, also I plan to read it again so that can change as well
Excellent manga right here worth giving a shot
