He possesses the supernatural ability to “dive” into the world of the past by touching left-behind items called “mementos.” Two years ago, Young’s wife was killed by an unknown assailant. In her last breath, she told him to “Look for D.” From that moment on, the search for 'D' became Young's whole life – nothing more, nothing less. Suddenly, he receives a case that might be related to 'D.'
