Summary
In 1888, seven years have passed since Dio came to the Joestar mansion and the mysterious Jack the Ripper has begun his murders. Elsewhere, the battle between Jonathan and Dio begins...

A rugby match is occurring at Hugh Hudson Academy and the hero of the team is Jonathan himself. Jonathan runs with ball in hand as many other opponents get on top of him. Jonathan just keeps dragging until a fourth player gets on him as well. With that, Jonathan passes the ball to Dio with which he's able to score and win the final match before graduation. Dio is graduating the top law student while Jonathan has written a magnificent thesis in the archaeological field. Jonathan even notices that Dio is referring to George as father instead of Lord Joestar as he used to call him. While everything seems good on the outside, Jonathan still can't feel any friendship for Dio. In reality, Dio has been acting good just to get through the years before he could be of legal age to gain the fortunes of the Joestars.

Back at the Joestar Mansion, George is shown to be sick in bed. At first it was thought to be a common cold, but it seems to be getting worse. George congratulations them on their rugby victory and is very proud of his two sons. That night, Jonathan is testing out the Stone Mask by putting a drop of his blood on it. Just like what happened seven years ago, tentacles sprout from the mask but soon go back to normal. While looking through some books, Jonathan accidentally drops a case. Inside the case is a letter from seven years ago that was sent from Dio's father, Dario, while on his death bed. To his shock, Jonathan realizes that the symptoms that Dario is describing are the same ones that George has. Jonathan goes to Dio to confront him.
