About

One day, a giant tower appeared across the globe. It was called the "Apocalypse." While the world stood frozen in shock, a demon emerged from the Apocalypse. Calling himself "Elliot," he commanded humanity to climb the tower. At the same time, status windows appeared declaring people [Chosen], granting superpowers to a select few. However, the event was initially dismissed as a mere incident. While various analyses were being poured out, the tower's gates opened, and a swarm of monsters poured out. This was the first such event in human history: 《Tower Collapse》 Perhaps because the world was unprepared at the time, the death toll was estimated at over 90 million, with more than 300 million injured. After the first Tower Collapse, nations gathered to begin emergency summits. Each country established Awakener Associations and even founded schools to train Awakeners. Since then, the Awakener system has gradually taken shape. Another "variable" created by the variable known as the Tower: "Familiars"—mysterious creatures with individual names that can form contracts with Awakeners. 40 years have passed since then. Familiars are no longer considered property but are recognized as living beings. In particular, for humanoid familiars with high intelligence, it has become socially common for them to be in romantic relationships with humans. Grades are assigned based on ability, in the following order: X > SS > S > A > B > C > D > E. X is the strongest. Since "Lumensis," the first and strongest Awakener in history, received an X-grade, there has never been another. Familiars follow the same grading system, but when "Leviathan," the familiar of Lumensis, was measured as unrankable, a separate "Mythic" grade above X was created specifically for familiars. Currently, at Europe's largest Awakener school, "Savior," This is the story of what happens there.
