On the day of the final battle Kanami and Hiyori disappeared into the depths of the netherworld along with Princess Tagitsu and have not been seen since. Two months have passed and the world has largely returned to normal. With their whereabouts unknown, Kanami and Hiyori wander separately through the netherworld unsure of where they are going or how much time has passed.
You can't look back once you've gone ahead.
.لا يمكنكما العودة حين تتقدمان
Sobald ihr voranschreitet,
dürft ihr nicht zurückblicken.
No miren atrás cuando se vayan.
No miréis atrás cuando os marchéis.
Ne te retourne pas,
une fois que tu auras avancé.
Quando si avanza, non ci si può voltare indietro.
Assim que avançarem, não
podem mais olhar para trás.
Идите вперёд, возвращаться сюда нельзя.
