Jonathan Joestar (Ogre Street) vs. Robert E. O. Speedwagon (Hat), Tattoo Guy, and Kempo Fighter
Unlock Criteria: Clear Chapter 04Dio breaks into Jonathan's desk and reads Jonathan's notes on the
Stone Mask. Dio decides to kill Jonathan by using the mask to pierce his brain, figuring that the police would assume Jonathan had accidentally killed himself during his research. Meanwhile, in London, Jonathan's carriage driver refuses to drive any further: the carriage has entered a particularly dangerous area of the city known as
Ogre Street. Jonathan decides to continue alone, intending to find the source of Dio's poison and obtain an antidote at any cost. Walking through the maze-like Ogre Street, Jonathan is attacked by three men. Sending his
two lackeys ahead of him, the leader of the group shows off the hidden blades within his bowler hat.
Jonathan defeats his attackers, but a mob of thugs surround him. Suddenly, the group's leader tells the mob to not harm Jonathan. Introducing himself as
Robert E. O. Speedwagon, the leader asks Jonathan why he held back while fighting him. Jonathan responds that he only seeks a way to help his father, and did not want to cause Speedwagon's family any distress. Amused by Jonathan's naivety and nobility, Speedwagon offers to take Jonathan to
Wang Chan, the poison seller he is looking for.
Meanwhile, in a port town near the Joestar mansion, Dio is distressed by Jonathan's uncertain fate. Though he expects Jonathan to die miserably on Ogre Street, he worries that his foe may have found an antidote to the poison, against all odds. As a result of his distressed state, Dio has taken to drink just as his late father did; the thought of following in his father's footsteps enrages him. Dio bumps into two older men on the street, who taunt him for being out so late at night. Dio, amused by the men's confidence, smashes his bottle into one of the men's faces. As the other man pulls out a knife to attack, Dio decides to use the opportunity to test his murder weapon.
Dio forces the Stone Mask onto his attacker's face and stabs the man's partner with his knife. The blood from the wound activates the mask, causing it to emit a strange, glowing light. The Stone Mask's human test subject appears to fall dead, only to get back up and attack him from behind. The newly-revived man approaches Dio and grabs him by the throat, sucking his blood through his fingers. As the man's face begins to de-age, Dio realizes that the mask has created a
Vampire. Luckily for Dio, the rising sun turns the Vampire into dust, leaving Dio to contemplate his options.
