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.
You're the only one left. 
 I will be the one to leave this cave.
.أنت آخر من تبقّى. سأكون القادر على مغادرة هذا الكهف
Nur noch du bist übrig!
Eres la única que queda.
Eres la única que queda.
Tu es la dernière en vie !
Sei l'ultima rimasta!
Só sobrou você, mas eu serei
o sobrevivente desta caverna!
Кроме тебя уже никого не осталось.
