Also known as: 静·乔斯达, 静・ジョースター, 透明婴儿
A baby girl who developed the Stand "Achtung Baby" (but wasn't able to control it) that rendered her invisible. She was discovered by Joseph Joestar (Old) (after her parents apparently lost her, possibly due to her invisibility) and adopted her as Shizuka Joestar into the Joestar family.
