In England during the 1880s, Jonathan, only son of the aristocratic family Joestar, strives to become the perfect gentleman. But when his family adopts a mysterious young man of a similar age, his life takes a new turn. This adoption is a result of an old promise between their two fathers: Dario Brando had saved George Joestar s life in their youth, and on his deathbed, asks that Joestar take care of his son.

But Dio is sneaky, ambitious and unscrupulous: he would do anything to get a hold of the Joestar fortune and destroy Jonathan s life.

Their fratricidal struggle will lead them down a dark and dangerous path, and follow them from generation to generation like a curse.
