Everyone around Futaba expects her to grow up and become an adult, and she's lost the ability to keep herself mentally balanced. At the bottom of her heart, her childish self is still there, and still strong. One day she wanders into another dimension, a world where the light has been lost, and darkness rules. The people there exist as babies wearing only their underpants...
It doesn't matter if you have someone 
from another world with you.
Es ist gleichgültig, ob du jemanden
aus einer anderen Welt bei dir hast.
No importa si te acompaña
alguien de otro mundo.
No importa si te acompaña
alguien de otro mundo.
Vous ne pouvez rien,
même avec cette fille.
Non importa che abbiate una persona
di un altro mondo con voi.
Não interessa se tem alguém
de outro mundo com você.
И существо из иного мира тебя не спасёт.
