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...
Do anything to her, and I'll haunt 
you and your kin forever.
إذا آذيتها فسألعنك أنت وسلالتك للأبد
Verletzt ihr sie, verfluche ich
euch und eure Nachkommen.
Si le hacen algo,
los maldeciré eternamente.
Si le hacéis algo,
os maldeciré eternamente.
Fais-lui du mal,
et je maudis toute ta lignée.
Torcetele un capello e perseguiterò voi 
e i vostri discendenti per l'eternità.
Faça algo com ela e eu vou perseguir 
você e seus descendentes para sempre.
Пальцем её тронете — 
и я прокляну весь ваш род.
