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...
Don't come in until I say it's all right, Satella.
لا تدخلي حتّى أقول أن الأمور
على ما يُرام يا ساتيلا
Komm nicht rein,
bevor ich Bescheid gebe, Satela.
No entres si no digo
que está bien, Satella.
No entres si no digo
que puedes, Satella.
Entre pas sans mon signal, Satela.
Non entrare finché non ti do
il via libera, Satella.
Não entre até eu dizer que
 está tudo bem, Satella.
Сателла, не заходи, 
пока я тебя не позову.
