Ren is haunted by the deaths of his party members in a failed attempt to defeat the Spirit Tortoise, and doesn't want to believe that he might be responsible for what happened.  Myne seems ready to take his side and support him, but...
It's not my fault at all!
!ليست غلطتي على الإطلاق
Es ist nicht meine Schuld!
No es culpa mía.
No es culpa mía. 
C’est pas ma faute.
Non è colpa mia.
Não é mesmo!
Не виноват я!
