Tsukina is summoned to another world and is told by a talking orb who introduces itself as a god that she is to be the savior of another world and that she is to balance it with her high magical power, whatever that means. Being already in her thirties, she refuses at first and tells the orb to leave it to those that are younger. Though there are already others that have been summoned to that world, it insists that she go, telling her that it'll grant her any wish in return. In response, she asks to have the strongest protection magic and requests for a function that allows her to summon any item as long as she googles for it. Thus begins her leisurely life in another world as she sets up a quiet and remote book café
