The progress of all four party members is halted by heavy snow as time continues to tick away. What's worse, if anyone freezes to death, they can't come back to life until the weather they revive in becomes survivable again. The party grows desperate. Yotsuya gets lost in an underground dungeon that he unexpectedly fell into, Shindou walks across a frozen lake without realizing how thin the ice beneath her feet is, and Hakozaki is unable to progress any further. As the party members lose their lives one by one, Tokitate, the last one alive, is ready to give up...
And what if the decision was an action 
taken by your parents twenty years ago?
وماذا لو كان القرار تصرّفاً من أبويك
قبل عشرين عاماً؟
Und was, wenn diese Entscheidung
vor 20 Jahren von euren Eltern gefällt worden wäre?
¿Y si la decisión en cuestión fue algo
que hicieron sus padres hace 20 años?
¿Y si la decisión fue tomada
por vuestros padres hace 20 años?
Et si cela était arrivé à vos parents,

E se la decisione fosse un'azione compiuta
dai tuoi genitori vent'anni fa?
E se a decisão foi uma ação tomada
por seus pais, vinte anos an?
А что, если решение было поступком
родителей двадцатилетней давности?
