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...
You guys... Did you see I was alone 
and decide to get revenge?
أنتُم... هل رأيتموني وحيداً فقرّرتُم الانتقام؟
Das wird wohl
die Rache für vorhin.
¿Vieron que estaba solo
y vinieron a vengarse?
¿Me pilláis solo y queréis venganza?
Vous profitez d’être à 3 contre 1
pour vous venger ?
Ancora voi... Avete visto che ero solo
e avete pensato di vendicarvi?
Vocês de novo... Viram que eu estava 
sozinho e resolveram se vingar?
Что, отомстить решили, пока я один?
