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...
Just so you know, I can't 
do anything to thank you.
لمعلوماتك، لا أستطيعُ فعل أي شيء لشكرِك
Para que sepas, no puedo agradecerte.
Que sepas que no podré agradecértelo.
N’attends rien en retour.
Ti avverto che non potrei ricambiare.
Só para que saiba, não posso 
fazer nada para te agradecer.
Говорю сразу: 
мне нечем отплатить.
