Absolutely one of the best manga I ever read. It has everything you need: great plot, a lot of character differentiation, even more deeper analysis of the main characters than the first manga and a lot of plot twists.
Plot (it can contain SPOILERS from the first manga): after the end of Tokyo Ghoul, the manga starts focusing on CCG, in particular Haise Sasaki, supervisor of the Quinx, the newest addition to the CCG's arsenal. These are teens with Ghoul implants, quite the same as Kaneki but "perfected", and used to counter ghouls. Starting from here, the mangaka managed to answer alot questions but open new holes in the "big picture", holes full of suspance and hype.
At the moment, chapter 92 is the last that came out, but also with this small number of chapters I can easily say that this manga satisfied me so much, that I decided to give it 9/10.
If you liked the first manga, you will like this more, its a whole new level of hype and psychological drama, of amazing fights and new great characters.
Also, you will likely reconsider one of two characters descripted previously.
P.S. I'm italian, so sorry if you read any language error. I tried to make this short and enthusiastic review as understandable as I could.
