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...

um dich zu beschützen?

a este mundo a protegerte.
Dijiste que vine

Você disse que eu vim para
este mundo protegê-lo?
Ты сказал, я прибыла сюда, 
дабы защитить тебя?
