No one noticed that Touka's special, blue-and-green, colors are in some of Sasaki's hair? In the cover picture.
Sorry about my bad English
Yeah I did notice the similarities, but I don't think that means much?
Anyway I read the scanlation by imperialscans and it seems like Sasaki is way too similar to Kaneki to be him. I mean, knowing what a troll Ishida actually is, I doubt he'll make it THAT obvious. So believing Sasaki is Kaneki is probably another part of his trolling plan.
So far I believe this: 3 years after Kaneki's "end", a group of half ghouls appeared, working for the CCG and being watched over by doctors and the like. They're commanded by Sasaki, who's under Mado's command, and who's also close to Arima. So either Kaneki IS Sasaki, but brainwashed and starting over, or Sasaki comes from Kaneki, as in, he's a normal human and they gave him one of Kaneki's organ or something like that to turn him into a half ghoul.
Because seriously? Same heigth and weigth, and same age (19 + 3) ? That seems way too big, I'm not trusting Ishida anymore.
Besides I don't remember Kaneki being that punny, but at the same time, the poor guy's life in TG was a tragedy from the beginning to the end so he never really showed that much humor.
At the same time, Amon and Kaneki were the two main characters on each side, and it would be ironical to turn Kaneki into Sasaki (a half ghoul becoming a ghoul investigator, a weapon to fight against his previous comrades) and Amon into a half ghoul (by Aogiri and Kanou, becoming one of the side he hated so much). That would be very ironical and horrible of Ishida...
