1x9 - Corpse Princess

Makina saves a bunch of students from a Corpse, specifically Kasuka (nicknamed Omune-sama), a girl who later becomes infatuated with Makina’s beauty of death. Later, Ouri investigates what happened to Minai from Makina with no success. Curious about Ouri’s insensitivity towards death, Makina approaches Keisei asking why he is so compassionate towards the Shikabane. Keisei shows us a flashback of Ouri’s first appearance at the orphanage, where we see an emotionless 3 year old Ouri. He had been detached from the world until he rescued a kitten crying by the riverbed. In a tragic twist, that cat died shortly after from a car accident. Ouri, affected by this incident, is aware of death constantly. Kasuka visits Makina bad mouthing Ouri, suggesting he would never know Makina like she does. Makina defends him by stating he knows more about her (death) than Kasuka ever will.
