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...
My family motto is "Give up your life, 
but not your underwear!"

"Perdi la vita, ma non le tue mutande!"
O lema da minha vida é:
"Dê a vida, mas não as cuecas!"
