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...
That's just some crap that stupid 
Hikaru picked up from a light novel!
Das ist doch nur so ’n geistiger Dünnpfiff,
den Hikaru aus einer Light Novel hat!
¡Son las estupideces que Hikaru
sacó de una novela!
¡Son las estupideces que Hikaru
sacó de una novela!
Avec lui, ça peut être
qu’une histoire de light novel !
Quelle sono solo delle sciocchezze che
Hikaru ha pescato in un romanzetto!
Aquilo é só uma bobagem que
o Hikaru leu numa light novel!
Дурачина Хикару из своих ранобэ
 всякий бред понарассказывал!
