This is the story of the hero who must kill the princess. In this world, the dead are sent to their final resting places by the Immortal Undertakers, a race of long-living, human-like beings. Leon, a half-breed, is the youngest of them and is on his way to take his final test when his train derails. He meets a human girl in the forest, and though he doesn't know her, he somehow feels he must protect her...from the other Undertakers! (Source: Mangamo)
