《推理之绊》（日语：スパイラル～推理の絆～）又名《少年侦探》，英文名《SPIRAL》，原是日本的漫画，后来推出电视动画以及小说,drama CD,画集等衍生作品。由于动画版结束时漫画还未连载完毕，所以动画版以原创故事收尾。其前传漫画《推理之绊 - 螺旋重现》(スパイラル・アライヴ)亦已连载完毕，为整个系列画下了休止符。

The battle with demons begins: can faith and strength save an innocent soul? Father Park, a priest excommunicated from his parish for practicing exorcism, is contacted by an old friend who asks for his help in protecting a child with special powers. Together they assemble a team of individuals with supernatural abilities to confront potent demonic forces. “Exorcism Chronicles” is among this year’s most eagerly awaited Korean films. Adapted from one of the country’s best-selling series of novels, its appeal lies not only in its suspense, but also in its fight sequences, as spectacular as those in the iconic Japanese “Dragon Ball” franchise.
