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.
made me think I shouldn't go about 
my studies aimlessly, either.
.أفكّر أنّه ليس عليّ أن أدرس بلا هدف أيضًا
nicht einfach nur so ziellos
vor mich hin zu lernen.
j’ai compris qu’étudier,
c’est aussi quelque chose d’important.
me fez pensar que também 
não devo estudar sem pensar.
