Aja Mask

"I don't intend on being a warrior like Wamuu, nor am I an idle dreamer. I don't care what method I have to use, victory justifies any means."

- Kars, user of the Aja Mask Aja Mask (アジャマスク) is a powerful artifact featured in the second part of JoJo's Bizarre Adventure, Battle Tendency. The mask was introduced as a combination of Red Stone of Aja and the Stone Mask. It is a mask that Kars used to become the Ultimate Lifeform and have immunity to sunlight, making him no longer a Pillar Man.

He modified the Stone Mask, so that the Red Stone of Aja could be used to activate it's powers.

Appearance
It takes the appearance of a usual Stone Mask but Kars's modification had let the Red Stone of Aja sit in the hole right where the forehead is.

Background
The Aja mask was made by Kars so that it could work on a Pillar Man, due to the fact that the regular Stone Mask couldn't function on a Pillar Man. During his search for the Aja Stone, Kars kept the mask until he succeeded in finding the stone. The mask broke once Kars used it.
