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.
I still haven't gone on a 
journey as long as that one.
رحلةً بطول تلك الرحلة
Ich habe mich seitdem nie wieder
auf so eine lange Reise begeben.
Nunca había emprendido
un viaje tan largo en toda mi vida.
Nunca había emprendido
un viaje tan largo en toda mi vida.
Je n’ai jamais entrepris
de voyage aussi long par la suite.
resta il più lungo 
che abbia mai fatto in tutta la mia vita.
ainda não fiz uma viagem
tão longa como aquela.
За всю мою жизнь это было
самое продолжительное путешествие.
