So no matter what happens next in tgre, but there’s probably going to be a reunion within the next few chapters, which could be :
– Kaneki’s group : Hinami’s in Cochlea, Kaneki’s guarding, Banjou and his group are probably going with Ayato to save Hinami ; if they request the help of the “re” ghouls, Tsukiyama will complete the former group
–Kirishima family : Based mostly off this post, but i think Arata’s missing/in quinque form? So if Touka also goes to save Hinami(which isn’t that unlikely since they were close) and a user of Arata’s quinque shows up, then shit’s going to get real
–Former Quinx Squad : Urie and Saiko and going to save Tooru, who is on the island where Kanou is located. Kanou has Shirazu’s body…and all the talk about zombies..
