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...
You can either come with 
me, or die by my blade!
Entweder du kommst mit mir
oder stirbst durch meine Klinge!
¡Puedes venir conmigo
o morir por mi espada!
¡Puedes venir conmigo
o morir por mi espada!
Venir avec moi,
ou vous frotter à mon sabre !
Potete morire sotto la mia lama,
Venha comigo ou morra
para a minha lâmina.
или пойдёшь со мной, 
или же падёшь от моего меча!
