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...
I won't be back too late, but you 
can have dinner without me.
لن أتأخّر في العودة، لكن يمكنُكِ
أن تتناولي العشاء من دوني
Ich komm zwar nicht zu spät heim,
aber iss ruhig schon zu Abend.
No volveré muy tarde.
Puedes cenar sin mí.
No volveré muy tarde.
Puedes cenar sin mí.
J’en aurai pas pour longtemps,
mais mange seule si tu veux.
Non farò tardi, 
ma cena pure senza di me.
Eu não vou demorar muito,
 mas pode jantar sem mim.
Это ненадолго, 
но можешь поужинать без меня.
