Red Stone of Aja

“

This is it... Nature's perfect miracle crystal. Without a single imperfection! The Super Aja!

”

—Lisa Lisa, Chapter 76: Ripple Teacher Lisa Lisa, Part 6

The Red Stone of Aja (エイジャの赤石, Eija no Sekiseki), more specifically the Super Aja (スーパーエイジャ, Supā Eija), is a perfect gemstone sought by the Pillar Men, and the main plot device of the second part of the JoJo's Bizarre Adventure series, Battle Tendency.

The stone can absorb and refract light one million times, causing it to emit a laser-like beam. Combined with the Stone Mask, it would unlock a Pillar Man's full potential, removing all weaknesses, including the inability to withstand sunlight and the Ripple.

History

Background

About 2,000 years ago, this perfect stone was in possession of an unnamed Roman Emperor.^[4] Kars, Esidisi, and Wamuu pursued it, and although successful in wiping out the entire Ripple clan at the time, they were ultimately unable to obtain it and went to sleep inside a stone wall.^[5] The circumstances under their failure to retrieve it are unknown. Despite the deaths of the Ripple users, they managed to keep the stone protected and somehow hid it. The Stone eventually ended up in the possession of Straizo, who gave it to Lisa Lisa before his death during the events of Battle Tendency.^[6]

Lisa Lisa reveals that there is a legend that claims destroying the stone would make it impossible to defeat the Pillar Men.^[7]

Battle Tendency

The Red Stone is first mentioned by the Pillar Men after their 2,000-year slumber. After promptly defeating both Joseph and Caesar, the three set off to begin their search for it. Caesar takes Joseph to Venice where they meet Ripple Master Lisa Lisa who auspiciously had the stone in her possession.

Esidisi manages to locate the stone and, after his initial defeat, is able to ship it to Switzerland. Before the stone can cross the border however, it is confiscated by the German Army, or more specifically Colonel Rudol von Stroheim. During his and Joseph's encounter with Kars, the red stone goes sliding off a cliff, but Joseph is able to retrieve it after some struggle. Lisa Lisa then hides the stone somewhere in Switzerland before she and Joseph confront the Pillar Men in Kars's fortress. After threatening to blow up the stone with a time bomb, Lisa Lisa forms an agreement to fight with the Pillar Men one-on-one. Joseph is sent back to the hotel where he finds the stone in Lisa Lisa's luggage and sets off to the Skeleton Heel Stone.

At the climax of Part 2, Kars was able to claim the Red Stone of Aja by tricking Lisa Lisa during their fight. He combined the Stone with his customized Stone Mask just as the heroes unleashed a barrage of UV light, enabling him to become the Ultimate Thing. Following his transformation, the Stone fell from Kars's broken mask, and Joseph Joestar grabbed it before running away. Later, Joseph instinctively holds up the Stone to intercept Kars's final attack, amplifying the villain's Ripple several times over into a beam that the Stone fired into the volcano beneath them. This causes the volcano to erupt and blast Kars into space. The whereabouts of the Stone afterwards are unknown.
