A man in a bar cracks his fingers before a fight. A pianist cracks his fingers before playing, but why in the world does Kaneki do this? In the start, it felt more like a symbolic gesture, but as I looked deeper, I feel Kaneki cracking his finger is more than just a symbolic attribute. It’s more like he wants to convey something. Hence I started investing it and here’s my theory.
The cracking of fingers symbolizes two things, the abuse and abused, i.e the victim. Jason behaved in a psychotic way, not because he was born with illness but because he was tortured by a violent investigator. The cracking of fingers is a portrayal of strength and dominance in a fight.
In chapter number sixty one, page fourteen if my memory serves me right, Jason was speaking to himself- “I’m not Yamori, I’m the investigator meeting the torture. I convinced myself”. The self suggestion gives Jason the strength and mentality to resist the sadist by becoming a sadist himself.
The same goes for Kaneki as well, as in his mind Yamori’s idealogy of the weak get trampled are strong. To add to that, is Rize’s inner voice which plays in his head every second. That’s the reason Kaneki sub consciously picked up Yamori’s habit of cracking fingers. It’s the symbolism for “I’m strong”
Furthermore, Hide even revealed that Kaneki is a very good at role playing, in layman terms putting on a mask. This is the keystone to Kaneki’s character. He was role playing someone else, i.e Jason and Rize who were much stronger than him.
In chapter 116, when Kaneki saw Rize’s state, he said “this is the Rize I knew and I talked to in the cafe”. Idependent, Bold and ruthless. That’s why I hate her strength. Also, Kaneki said something along these lines
“If the Rize I don’t know doesn’t exist anymore, my strength was nothing but an illusion. “
This is where he started to crumble, the centipede in hos ear starts fading, Jason dies and lastly the strength which he received impersonating the two also start to fade. Hence he cracks his fingers as a way of fooling himself that he is indeed strong.
Thank you for reading my theory. Don’t forget to add your thoughts in the comments. Love ya guys <3 <3 <3
