Dullahans are demi-humans whose heads are separate from their bodies. Naturally, Tetsuo is intrigued by the unique traits of dullahans, but Kyouko is just as interested in learning more about her own body. Tetsuo has the idea to ask the opinion of someone outside of his own background in biology, so he takes Kyouko to meet Souma, an old college buddy.
I don't doubt you, but on what grounds 
do you say this neck exists?
أنا لا أشكّ فيك، لكن على أيّ أساس
تقول أنّ هذا العنق موجود؟
Anzweifeln würde ich das nicht,
No dudo de ti,
No dudo de ti,
Je veux bien te croire,
mais sur quoi te bases-tu ?
Non voglio dubitare di te,
Não duvido de você, mas no que 
fundamenta a existência desse pescoço?
Я тебе верю, но на каком основании
ты считаешь, что шея существует?
