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.

Dann werde ich mit ganzer Kraft kämpfen.

Então eu vou lutar com todas as forças!
Тогда я... буду драться в полную силу!
