Chapter 64 of "Tokyo Ghoul: Re" is already available online through Manga Fox. The latest chapter picks up from the shocking revelation of Eto and its repercussions. Before discussing any predictions and possible events in the upcoming chapter, here's the recap of the latest events.
Eto just revealed that she's actually a ghoul and her books are somehow a revelation of who she is and the situation they are in. The public was also made aware that she is under the custody of CCG that practically divides public opinion.
Meanwhile, Hogi reported the status of Aogiri Tree where they have confirmed the location of Aogiri Tree. Hogi also reported the status of the group and emphasized the status of Mutsuki who survived the attack but currently in custody by the Aogiri Tree. It was later revealed that Mutsuki is under the custody of Torso. Mutsuki was amputated and Torso appears to physically attack her.
Following the revelation, Ken asked Eto about the extent of her revelation. Eto further revealed that the Wushu Clan was actually working with ghouls and V Organization. The ghoul horror writer also took Ken by surprise by the fact that some RCs were rigged so that certain ghouls will not be detected and one of those persons who should not be detected is Ken. The chapter ends with the story of Rize and Shachi. The ghoul warrior is back with Rize.
User End at Manga Helpers speculates, "that the Wushu clan is divided into the main and branch family. And that Hide might be in the main branch that has complete knowledge over ghouls and are protecting them." On the other hand, forum users at Reddit is very excited for the return of Shachi. As a powerful ghoul, he should be facing some serious challenges in the upcoming chapters.
