At first, this manga may not have the most original concept or story. However, the way it runs is excellent.

The author finished the manga and began the sequel a month later. He likes to play with people like that. It's a direct sequel beginning 3 years after the end of Tokyo Ghoul. Without ruining anything, there are answers and that will put an end to your anger.

The manga is incredible, the characters are very well written, each character is important and has a proper and meaningful development for the story, and none of them are there just because they are there, nor are they useless. The characters have realistic personalities and none of them is just "good" or "bad." Each character is well developed and continues to develop and none of them are completely innocent, just as it is in real life.

I liked the fact that the characters are like this and this manga develops it perfectly.

Ken Kaneki is by far one of the best characters ever developed in history. He's not just the nerd or the cool emo badass. Just like any person in real life, he has secrets that he wants to keep buried and is not willing to accept. It has several stages of development that really make sense in the situations in which it is. Your motives and thought processes are excellently displayed.

Another good thing is how the manga not only feeds the facts. They are prefigured with various references to numbers, tarot cards, symbolism and metaphors, but unless you pay attention to what you read, you will not notice them and you will not be able to enjoy the manga in all its glory. I would recommend not only reading the manga only once, but at least several times to understand what you may perhaps not have understood or not noticed.

Overall it's an amazing manga with beautiful art and history, and the end of the cliffhanger was really the best way to finish the first part.
