Tokyo Ghoul: Re volume 1 (Spoilers)

HERE maybe you'll find Tokyo Ghoul:Re spoilers :)

Okey!!!! I have just finished the first volume of the manga Tokyo Ghoul: Re, the continuation of Tokyo Ghoul. It take place two years after the battle of the CCG versus the ghoul owl. It's so strange, Kaneki (his hair changed... again...) works with the CCG, he teach four half ghouls, half humans, it's a kind of experiment that made the CCG with these teens. It seems that Kaneki don't remember anything of his first 20 years of his life. And now he has other name, Sasaki or something like that....
It also appears Akira Mado and Arima, but Kotaro don't appear (at the moment...), did he die at the battle of the CCG versus the ghoul owl? I don't think it, he lost an arm and a leg but he did not die. At the end of volume 14 of  Tokyo Ghoul they said that Kotaro is death

 but they did not said that they found his body.
And Yomo apear as a Sierpe!!! (Ghoul rang S that CCG is investigating)
And the most impacting thing is when Touka appears at the end of the manga, Sasaki (Kaneki) and his "students" go to a bar and Touka is working there with Yomo. But Kaneki DON'T remember anythig of his life SO he DON'T KNOW that Touka is TOUKA. Probably Touka knowed that he was Kaneki.
Well, ... today I will continue the volume 2 (I started yesterday but I only read the first pages).
See you, Aina :3
