Tsukiyama is happy for Kaneki and Touka. He really is.
But he’s lonely, and Karren isn’t coming back, and now Kaneki is officially taken, or touken. He chuckles at his own wit.
He knows he doesn’t value life. Not like he should.
He remembers breaking into homes and taking eyes for snacks all too easily, laughing as he feasted on flaky old man shin, setting up dozens in the Ghoul Restaurant.
He is the last person who should be involved in GOAT, and yet here he is, feeling like he knows better than its leader.
Kids are kids are kids. He doesn’t want to kill the little twerp Hajime. But if it’s us or them, Tsukiyama will ensure it’s them.
Kaneki wants peace by pacifism, and Tsukiyama wants to believe in it himself, but he can’t.
For them to live – for Touka to carry that baby she isn’t hiding as well as she thinks – people must die.
Just like for him to live, Karren had to die.
Or did she? Chie said there ought to be another way.
He wishes he could see one.
Karren died to ensure his survival. He will honor her sacrifice until the end of his long, long life.
(And when he does meet someone else, he’ll name their firstborn/first adopted Karren, and save Shuu Jr. for the second).
