Moroha once had a master named Yawaragi, who was keeping a life-threatening secret. In order to resolve the secret and protect her pupil, Yawaragi made an agreement with Jyubei.
I'm not a demon. I'm not a human. 
 I'm not even a half-demon.
.لست شيطانة. لست بشريّة. لست نصف شيطانيّة حتى
No soy demonio, no soy humana,
y ni siquiera soy mitad demonio.
Não sou youkai. Não sou humana.
Não sou nem meio-youkai.
