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.

you'll regret it the rest of your life!
wirst du das bis ans Ende deines Lebens bereuen!
lo lamentarás por siempre.
lo lamentarás para siempre.
lo rimpiangerai per il resto della vita!
vai se arrepender para o resto da vida!
и будешь сожалеть до конца своих дней!
