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.
To choose one thing means 
to give up something else.
Quand on choisit une chose,
il faut en abandonner une autre.
A ogni scelta corrisponde una rinuncia.
Escolher uma coisa significa desistir de outra.
