In a world where every human is assigned a coded ability, Riku Hoshino is a “Null”—a system error with no recorded power. But when a deadly glitch invades reality, everything changes. The monsters don’t attack the strongest… they hunt only him. Taken to the elite Shadow Code Academy, Riku discovers a forbidden truth: his existence itself is a crack in the system, and something ancient is trying to erase him from reality. As powers awaken, alliances form, and the world begins to break, Riku must decide—survive as an error… or become the force that rewrites the system itself.
