The reason Olivia is so fond and protective of Noir is revealed. It has to do with an adventurer from the past. Meanwhile, Noir fights for his life against the fake Olivia. Will he be able to figure something out?
It won't change the past, 
and the regrets remain.
هذا لن يغيّر الماضي، وستبقى الحسرات قائمة
No cambiará el pasado
ni me librará de mi arrepentimiento.
No cambiará el pasado
ni me librará de mi arrepentimiento.
Non può cambiare il passato 
e nemmeno cancellare il rimorso.
Não posso mudar o passado,
e o arrependimento se mantém.
Прошлого не изменить, 
сожаления останутся.
