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 told you, finding your insignia will 
be my one good deed for the day!
قلتُ لكِ، سيكونُ العثور على شارتكِ من إحدى
أعمال الخير التي أقومُ بها كلّ يوم
Ich hab doch gesagt, ich helfe dir.
Jeden Tag eine gute Tat!
Je ferai une bonne action par jour
en t’aidant dans tes recherches.
Te l'ho detto, trovare il tuo stemma
sarà la mia buona azione della giornata!
Eu te disse, achar o seu brasão 
vai ser a minha boa ação do dia!
Моя цель — вернуть твою печать. 
Одно хорошее дело в день.
