"Omae wa...nani o shiou to shite iru? Doko e ikou to iu no da?"
"You...what are you trying to do? Where are you trying to go?"

"Anata wa...dare?"
"Who...are you?"

"Utsurowazarumono."
"The One Who Destroys"(lit. The one who changes (the world) to nothing)

"Shinjitemashita yo...saishou kara."
"I've believed in you...ever since the beginning."

"Souda to iu no ka!? Chigau! Hito wa...hito wa sonna ni yogoretewa inai!"
"So is that what it is? You're wrong! Humans...humans aren't so evil!"
