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...
If that happens to you again, saving you 
won't be of any benefit to me,
إن تكرّرَ حدوث ذلك، فإنّ إنقاذك لن ينفعني بشيء
Beim nächsten Mal gibt es keinen
Grund für mich, dich zu retten.
Si eso te pasa de nuevo,
no obtendré nada por salvarte,
Si te metes en líos de nuevo,
no ganaré nada ayudándote,
Je ne gagne absolument rien
en te sauvant la vie,
Se dovesse succederti di nuovo, 
salvarti non mi porterebbe alcun beneficio,
Se isso acontecer novamente, não 
verei nenhum benefício em te salvar,
В другой раз спасать тебя будем незачем,
