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...
But this world is set up so that I'll be strong!
لكن هذا العالم مُهيّأ لأكون قوياً
Also bin ich in dieser Welt
doch ’n Kraftpaket!
¡Parece que esto está hecho
para que sea muy fuerte!
¡Parece que esto está hecho
para que sea muy fuerte!
Mais j’avais raison,
je dépote, dans ce monde !
Ma questo mondo è strutturato 
per rendermi forte!
Mas este mundo foi formado
 para que eu fosse forte!
Но в этом мире я всё-таки силён!
