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're the version of my mother 
from the great disaster,
،أنتِ نسخة والدتي من الكارثة العظيمة
Du bist die Version meiner Mutter
von der großen Katastrophe,
Eres la versión de mi mamá
del gran desastre,
Eres la versión del gran desastre
de mi madre,
Tu sei la versione di mia madre 
risalente al Grande Disastro,
você é a versão da minha mãe,
do dia do grande desastre.
Ты мама, какой она была
в момент катастрофы.
