It's the night before the Mai High Festival.  Keima and Chihiro are alone on the roof of the school.  Chihiro seems confused by Keima's behavior, but he continues with his conquest.  But as Keima makes his move, Chihiro says something unexpected.
But I can't believe there was 
a place like that inside the rock.
Pero sigo sorprendida por lo que había ahí.
Pero sigo sorprendida por 
lo que había ahí dentro.
Mas eu não acredito que tinha um
 lugar daqueles dentro da pedra.
