A decade ago, a fairy named Daisy appeared and asked the child Eiji Hoshimiya what his single, ultimate wish was. While the content of his wish remains unknown, the aftermath was devastating. During an incident known as the "Great Destruction," the world began to crumble as everything collapsed, resulting in countless deaths. Eiji is now a high school student whose primary concern is his ill sister. He has no recollection of what he wished for; he only remembers that his wish triggered the Great Destruction. Since that event, thousands of others have acquired the ability to fulfill their heart's desires. These individuals, referred to as "Orders," are widely regarded as evil and despised by the public. Nevertheless, some Orders are hunting Eiji for revenge regarding those he killed. Will Eiji manage to survive the many assassination attempts? And the greatest mystery of all: what did he wish for, and what were his intentions in making a wish that caused such widespread desolation?
