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...
How we met when I picked 
you up off the floor...
Wie wir uns trafen,
als ich dich vom Boden auflas …
Como nos conocimos
cuando te recogí del suelo…
Cómo nos conocimos
cuando te recogí del suelo…
Quand je t’ai ramassé
sur le plancher, notre rencontre !
Come ci siamo incontrati,
quando ti ho raccolto da terra...
Como quando nos encontramos e
eu peguei você no chão!
Нашу первую встречу, я поднял тебя с пола!
