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..Or Arata himself will be there maybe. 😉
