The ending of the second season of Tokyo Ghoul left many viewers confused and puzzled. In the end, Kim Muyan was forced to enter a basement called "Cage" to communicate with some other humans.
It was speculated that this basement might be a research facility or a place used by an organization to modify humans. In the communication between these humans, Jin Muyan discovered that they all had a common goal, which was to destroy all the ghouls. However, in the process of communicating with a certain woman, Jin Muyan was deeply attracted and began to waver.
This woman could be the manager of a research facility or a member of an organization related to ghouls. It was still unclear whether Jin Muyan would choose to join these organizations or continue to keep a distance from them. However, this ending was indeed meaningful and thought-provoking.
The green-haired woman in the second season of Tokyo Ghoul was Ginko. She was one of the members of the Corpse Organization and also the classmate of the protagonist, Jin Muyan. At the end of the first season, she was portrayed as a very smart and ambitious character who wanted to become the leader of the ghoul organization. In the second season, she showed a more complicated and dangerous personality and had more connections with Kim Muyan.
It depends on personal preferences. Some people might think Tokyo Ghoul is better for its original story and character development. Others might prefer Tokyo Ghoul:Re for its continuation and new plot twists.
Season 3 of Tokyo Ghoul has a mixed relationship with the manga. While it retains some key elements, it also takes liberties that may not sit well with manga purists. Some story arcs are condensed or altered, affecting the overall coherence compared to the manga.
