The volume cover of vol. 10 11 and 12 is like saying, speak no evil, see no evil and hear no evil. Urie is aware of it but doesn't speak of it. Mutsuki sees it and accepted it. Saiko hears about it and chose/will choose to reject it.
Just wanna throw it here.
Kaneki migth cannibalize a Qs member.
And they say that mutsuki mirrors kaneki in the original story but she's just insane..
The chapter reminds me of the kaneki kidnapping arc in the original story..
