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...
Now, am I walking into a 
demon nest or a snake pit?
هل أدخل وكر شيطان أو حفرة أفاعٍ الآن؟
Ob wohl ein Gespenst
oder ein Teufel auftaucht?
Bueno, ¿es la cueva del lobo
o un pozo de los mil demonios?
Bueno, ¿es la cueva del lobo
o un pozo de los mil demonios?
Qu’est-ce qui m’attend
dans cette baraque miteuse ?
Allora, sto entrando 
in un covo di demoni o in una tana di serpenti?
E então, estou entrando em um 
ninho de cobras ou demônios?
И кто тут, демоны, гадюки?
