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.
My mom suddenly went into labor,
دخلت أمّي المخاض فجأةً
Mi mamá entró en trabajo de parto,
Mi madre se puso de parto
Mia madre è entrata 
improvvisamente in travaglio,
Minha mãe de repente
entrou em trabalho de parto,
Мама вдруг взяла и родила.
