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...
And our underwear is our life.
Die Unterwäsche bedeutet unser Leben.
Y la ropa interior es nuestra vida.
Y la ropa interior es nuestra vida.
Et la culotte, c’est notre vie !
E le nostre mutande sono vitali.
E sua roupa de baixo é sua vida.
А нижнее бельё — наше всё!
