The most story ever.

It's long as fuck but figuring out the mystery and seeing the world evolve is an indescribable feeling. It took me a month to read this, I hated it and I loved it.

I wish I could erase my memory to read it the first time again. (But rereading a few, select scenes again is another experience too)

I will say, if you're the type of person that can't sit through long scenes, some of them even unnecessary, the manga does a good job.
