Leaving behind nothing more than a note, Mana suddenly disappears. 
Ren and the crew try to piece together where she could have gone, 
eventually going to speak to the heavily-injured Walpurgis. 
When Walpurgis tells them Mana's secret and her plan to sacrifice herself, 
Ren and crew rush to save her.
I'm sorry. These horrible injuries 
happened to you because of me.
Entschuldige, dass du meinetwegen
solches Leid ertragen musst.
Excuse-moi.
Ce qui t’arrive est ma faute.
mi dispiace. 
Tutto questo è colpa mia.
Me perdoe. Você ficou com 
ferimentos horríveis por minha culpa.
