Natsuki Subaru is summoned to a parallel world on his way home from the convenience store. He's entranced at first by the fantasy world suddenly stretching before his eyes, but the cute girl he believes summoned him is nowhere to be found, and soon enough he's utterly lost. Then a gang of punks surrounds him, but he quickly learns that he doesn't have any of the powers that he thought all people transported to a parellel world should have. Just when he's about to be beaten senseless, a girl appears...
So at night, I return to the crystal 
I was summoned from
لهذا أعود ليلاً إلى البلُّورة التي استُدعيتُ منها
Nachts ziehe ich mich
in meinen Kristall zurück …
De noche regreso al cristal
del que me invocaron
De noche regreso al cristal
del que me invocaron
La nuit,
je retourne dans mon cristal
Così di notte torno nel cristallo 
da cui sono stato evocato
Então à noite eu volto para o 
cristal do qual sou invocado
На ночь я прячусь в кристалл, из которого
меня призвали, и жду восхода солнца.
