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.
Then he was more interested in protecting 
his heart than protecting you!
!هذا يعني أنّه كان مهتمًّا بحماية قبله أكثر منك
So hätte er damals weniger Euch …
Tal vez le interesase más proteger 
su corazón que protegerlo a usted.
¡Entonces, le interesaba más 
 proteger su corazón que protegerlo a usted!
Et donc, la dernière fois,
In tal caso, non avrebbe protetto lei, Signorino,
 ma il suo stesso cuore.
Então ele estava mais interessado em
 proteger o coração dele do que você!
