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...
It's just a thoughtful arrangement we made

J’ai été assez sympa
pour te réconforter
È stata solo una premura per metterti a tuo agio.
Finché non ti fossi svegliato, almeno.
Foi apenas um plano que tivemos,
Мы просто решили: 
пусть порадуется, пока не придёт в себя.
