Detective Conan is about 16 year old high school detective Shin'ichi Kudou who while investigating some suspicious activity, was poisoned and left for dead. But the poison instead of killing him had the unexpected effect of physically rejuvenating him back to the form of a 6 year old. At the prompting of his friend and nominal guardian Professor Agasa, he is hiding his real identity, and is living under the assumed name of Conan Edogawa. Agasa has arranged for Conan to live with Shin'ichi's girlfriend Ran, and her detective father Kogorou Mouri, without them knowing who Conan really is. Using gadgets of Agasa's design Conan is secretly aiding Kogorou in the hopes of coming across information relating to the mysterious Black Origination so that he can undo his transformation.
