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'll go in first. You stay outside 
and keep watch.
سأدخلُ قبلكِ، ابقي في الخارج وراقبي
Ich geh zuerst hinein,
pass hier draußen auf.
Iré primero. Vigila aquí afuera.
Iré delante. Vigila aquí afuera.
Je rentre en premier,
monte la garde.
Entro prima io.
Tu stai qui e fai la guardia.
Vou entrar primeiro. 
Espere aqui fora e fique de vigia.
Я пойду первым, а ты постой настороже.
