This is one of the most thought provoking pieces of media I have ever seen. Right from the start the characters are so intriguing and there's already such a good air of mystery and as it goes on it just never gets less interesting. You never wanna stop reading (the physical release not separating chapters definitely helps this lol) yet at the same time you HAVE to because you need to let everything sink in. There is SO much the author wants to convey and so many genuinely important and worthwhile messages to the reader which are not forcibly thrown into the story but rather conveyed through actually well written characters with amazing development. At the same time there's so many aspects of the story that keep you thinking about it after you finish it, whether that be the extremely profound thematic stuff or intentional mysteries that aren't entirely cleared up. Oh and obviously the art is unreal levels of amazing.
Can be beautiful, disgusting, funny or horrifying, but most of all very very tragic and profound. It has some very heavy content & isn't exactly for everyone (watch out if you have s.a. trauma) but in my opinion this truly is easily a 10/10.
