High school freshman Daimon Kaito is a genius when it comes to solving puzzles. One day he received a strange device along with an invitation from a person named Minotaur to solve a puzzle in a ruin. He was accompanied by friend Itou Nonoha who, although not as good with puzzles like Kaito, managed to help him in dangerous situations. At the center of the maze, Kaito found a bangle which helped him solve the problem within a short time. The bangle is known as Orpheus which glows whenever Kaito is forced to solve an impossible puzzle. The group behind the life-threatening puzzles is known as POG. Kaito, now a Solver, teams up with fellow puzzle geniuses to solve POG's puzzles and find out the group's purpose in creating such problems.
