Saori’s quest for survival suddenly begins when she is transported to a different world along with her entire convenience store. She encounters demons, the mysteries of lifelines, and the shop ordering system as well as the existence of gods, heroes, demon lords, fairies, and angels. Saori grew up in a foreign land where various strange things are commonplace, and through various encounters with Randolph the knight and Elliot the treasure hunter. With an angel by her side and an angel quill in her hand, Saori seemed to have found a way to live in this world, but soon… She was involved in the existence of Demon Lord Alan, the “Demon Lord One Year Rule” in this world.
