JoJo's Bizarre Adventure season 1

The first season of the 2012 anime television series JoJo's Bizarre Adventure (ジョジョの奇妙な冒険) by David Production, also known as JoJo's Bizarre Adventure: The Animation, adapted the first two arcs of Hirohiko Araki's manga of the same name: Phantom Blood (ファントムブラッド) and Battle Tendency (戦闘潮流). The Phantom Blood arc, which aired on Tokyo MX between October 6 and December 1, 2012, revolves around the mysterious adventures of the Joestar family, beginning with an encounter involving Jonathan Joestar, his adoptive brother Dio Brando, and a Stone Mask that transforms people into vampires. The Battle Tendency arc, which aired on Tokyo MX between December 8, 2012, and April 6, 2013, focuses on Jonathan's grandson, Joseph Joestar, and his fight against the Pillar Men, ancient humanoids which created the Stone Mask.

The series was released on a series of nine DVDs and Blu-rays between January 30 and September 27, 2013, with the Blu-ray releases having the option of English subtitles. Crunchyroll began streaming the series in April 2014. The English DVD was released by Warner Home Video on September 22, 2015, with both English and Japanese audio with closed captioning for the English dub only. Viz Media released an English Blu-ray set on July 25, 2017, that includes English and Japanese audio with new subtitles for the Japanese. A second season, JoJo's Bizarre Adventure: Stardust Crusaders, based on the series' third arc, began airing from April 5, 2014.

Plot
The first season was split into two parts: part 1 comprised episodes 1–9 covering the Phantom Blood manga arc, and part 2 comprised episodes 10–26 covering the Battle Tendency arc.

The first part, Phantom Blood, is set in the early-to-late 1880s in England. George Joestar takes in the orphan Dio Brando to pay off a debt to Dio's late father Dario. Dio's attempts to become the sole heir to the Joestar fortune are thwarted and he resorts to using an ancient Stone Mask which transforms him into a vampire with his sights now set on world domination. With Will A. Zeppeli, a master of a supernatural ability called Hamon, and former street thug Robert E.O. Speedwagon at his side, George's son Jonathan trains in Hamon and stops Dio who is left aboard an exploding ship after he mortally wounds Jonathan. However, Jonathan's wife Erina is pregnant with a child and escapes, continuing the Joestar name.

The second part, Battle Tendency, takes place in 1939. Jonathan's grandson Joseph teams up with Will's grandson Caesar Zeppeli to battle ancient humanoids called the Pillar Men, but are overwhelmed by the Pillar Man Wamuu. Joseph and Caesar have a month to defeat the Pillar Men Esidisi and Wamuu to obtain the antidotes for the poisoned rings in Joseph's windpipe and aorta, while also preventing them from gaining a powerful stone called the Red Stone of Aja. The two are trained in controlling Hamon by the Hamon coach Lisa Lisa. Joseph defeats Esidisi and Wamuu, but Kars obtains the Red Stone of Aja, becoming more powerful. Aided by the German soldier Rudol von Stroheim, Joseph uses the Red Stone of Aja against Kars to defeat him. In the epilogue set in the 1980s, a "treasure chest" engraved with the name "Dio" is salvaged from the sea, while an older Joseph is set to meet his daughter in Japan.

Music
The first season of JoJo's Bizarre Adventure uses three pieces of theme music, two opening themes and one ending theme.
