Ep. 10: Tetsuo and Kyouko seek Souma's perspective on dullahan biology and bodily traits.
Aired on March 12, 2017

Dullahans are demi-humans characterized by heads that are separate from their bodies. Tetsuo feels intrigued by these unique traits, while Kyouko is equally interested in learning more about her own body. To gain a different perspective, Tetsuo decides to consult someone outside of his own background in biology. He takes Kyouko to meet Souma, who is an old college buddy. This meeting allows them to discuss their curiosities with a friend who offers a viewpoint distinct from Tetsuo's scientific knowledge, facilitating a deeper understanding of the subject matter through personal connection rather than academic study alone.
