Joseph Joestar of New York (1) (ニューヨークのジョセフ・ジョースター その① Nyū Yōku no Josefu Jōsutā Sono 1?), originally New York's JoJo (ニューヨークのジョジョ Nyū Yōku no 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 tankōbon release, this chapter is included in the JoJonium release of Battle Tendency rather than in the last volume of the previous part, Phantom Blood.
Battle Tendency is set in 1938, 49 years after the events of Phantom Blood. Friends of Jonathan, Speedwagon and Straizo meet once again. Speedwagon has become a rich oil tycoon and Straizo has 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 dozens of 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 large, strange man.
Meanwhile, in New York, a young British man has his wallet stolen by a young African-American pick-pocket named Smokey Brown, before saving him from two corrupt policemen using the Ripple. The man reveals himself to be named Joseph "JoJo" Joestar, and tells his newfound friend that he had unknowingly inherited the strange technique from his grandfather, Jonathan.
