Synopsis
Kaito Daimon seems like an ordinary high school student, but he possesses an extraordinary talent for solving puzzles—so much so that he's known as a "demon" at it. When he is invited to take some "special" tests meant to assess his unique ability, he quickly becomes suspicious that the test itself is a riddle to be cracked. Soon, Kaito finds himself entangled in a deadly Philosopher's Puzzle created by the sinister organization POG, a lethal maze filled with traps where failing to solve the secret correctly means death. Fortunately, his skills prove sufficient for the first challenge, saving both himself and his childhood friend Nanoha, who is also trapped in the deadly scheme. However, once Kaito is designated as a Solver, he is thrust into a new life, traveling the world alongside other Solvers to unravel the latest lethal conundrums left by POG. Every corner hides a fresh puzzle, and every deception could lead to death—but once a riddle is posed, Kaito can be counted on to unfold, unravel, and unlock it.
