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.
Behind every act is human intention.
.هنالك نيّة بشريّة خلف كّل فعل
Hinter der Handlung steckt
der Wille des Menschen.
Tras cada acto, hay intención humana.
Tras cada acto, hay intención humana.
E dietro ogni atto c'è la volontà umana!
Há uma intenção por trás 
de cada ação humana.
За каждым действием
стоит человеческая воля.
