Chapter 45

New York's Joseph Joestar (1), originally New York's JoJo in the WSJ release, is the forty-fifth chapter of the JoJo's Bizarre Adventure manga. It is also the very first chapter of Battle Tendency. Additionally, unlike in the tankoubon release, this chapter is included in the JoJonium release of Battle Tendency rather than in the last volume of the previous part, Phantom Blood.

Summary
Battle Tendency is set in 1938, 49 years after the events of Phantom Blood. Speedwagon has become a rich oil tycoon and Straizo succeeded Tonpetty as master of the Ripple.

Speedwagon and Straizo travel to Mexico to investigate a mysterious underground cavern. Inside, they discover a large stone pillar decorated with stone masks similar to the one they had gone to great pains to destroy forty-nine years ago. Embedded in the pillar is also the body of a strange man.

Meanwhile, in New York, Jonathan's grandson, Joseph Joestar (also nicknamed "JoJo"), saves a young African-American pick-pocket named Smokey Brown from a couple of corrupt policemen using the Ripple, which he had unknowingly inherited from his grandfather.
