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 feel like an idiot for 
trying to cheer you up!
!أشعر أني مغفّل لأني حاولت رفع معنوياتك
Was brech ich mir hier einen ab?
¡Me siento como un idiota!
¡Me siento como un idiota!
Pourquoi je te remonte le moral ?
Ed io che mi preoccupavo per te.
Agora me sinto um 
idiota por tentar te animar!
