Mutsuki’s Fate? (Spoilers)
I’ve just finished reading Tokyo Ghoul:re chapter 77 and I thought I’d make a post about Mutsuki’s fate. I’ll keep this short and simple. I can’t say for certain, but I believe it’s unlikely that Mutsuki is dead. I believe Mutsuki realised to free himself from this abuse, he had to take action and did so by killing Torso. He did it by dismembering and decapitating him so he becomes literally what his name is, hence the torso at the end. This is pure speculation, so don’t take my word for it.
