The boy Yotsuya saved in the Chinese restaurant, Torii Keita, turns out to be the fifth player. They're sent to the alternate world again, and after receiving the fifth quest, they head for Cortonel to track down some leads. There they find Kahvel, who is now a mother. The party is shocked to learn that 15 years have passed since their fourth quest, but that isn't the only thing that's changed in this world.

from it that I survived Hell.
أظنّ امتلاكي لتلك الذكريات هو

Ich glaube, dass ich
Si pude sobrevivir al infierno
fue gracias a todos esos recuerdos.
Si pude sobrevivir al infierno
fue gracias a todos esos recuerdos.
Je pense avoir pu survivre à l’enfer
grâce à ces souvenirs.
Credo sia merito dei ricordi di quell'esperienza 
se sono riuscita a sopravvivere all'inferno.
Acho que é por ter essas lembranças
que sobrevivi ao inferno.
Думаю, благодаря тем воспоминаниям
я и смогла пережить ад.
