Hiiro realizes that he possesses Dagan Zot's heart, and that if he dies, Dagan Zot will die as well.  Only after Giruu reveals the depths of his devotion does Hiiro find the strength to carry on.
I'll put an end to your suffering now.
سأضع حدًّا لمعاناتك الآن
Lass mich dich erlösen.
Le pondré fin a tu sufrimiento.
Le pondré fin a tu sufrimiento.
Je vais t’offrir le repos éternel.
Porrò fine al tuo dolore con le mie stesse mani.
Vou dar um fim ao seu 
sofrimento agora mesmo.
