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.
Bihmsberg wouldn't have died if 
it hadn't been for me, either.
لم يكن بيمزبيرغ-سان ليموت
لو لم أقحمه
Und auch Bihmsberg
Anche Bihmsberg non sarebbe morto 
se non fosse stato per me.
O Bihmsberg-san também estaria vivo
se não estivesse comigo.
А ещё, если бы не я, то Бимсберг
был бы по-прежнему жив.
