Subaru risked his life to save the children from a pack of Ulgarm, but he was so powerfully cursed that there could be no saving him. Even Beatrice is unable to undo the complex web of curses on him, and says he'll grow weak and die within half a day. The only way he can survive is if the entire Ulgarm pack is defeated, but time is not on his side. Subaru is ready to give up when he learns that Rem has gone into the forest by herself...  Knocked unconscious by Subaru's attack, Rem dreams of an event in her past that she and Ram would rather forget... a sin for which Rem feels she can never be forgiven. After waking up, she tells Subaru that she's just committed the same sin again. When the three of them are moments from being cornered by the Ulgarm pack, Subaru takes off to draw their attention so Ram and Rem can escape.
If you expect me to be able to fight like 
Rem does in her demon form, I can't.
إن كنت تتوقّعُ أنني أستطيعُ القتال كما تفعلُ ريم
بهيئتها الشيطانيّة فأنت مخطئ
Wenn du glaubst, dass ich wie Rem
kämpfen kann, wenn sie zum Oni wird, nein.
Si esperas que pelee como Rem
en su forma de ogro, no puedo.
Si esperas que pelee como Rem
en su forma de ogro, no puedo.
Je ne peux pas me transformer
et combattre comme Rem.
Non so cosa ti aspetti, ma non posso combattere
in forma demoniaca come Rem.
Se você espera que eu lute como a Rem na
 forma de demônio dela, saiba que não consigo.
Смотри, от Рем в демонической форме
 пользы куда больше, чем от меня.
