Pandora

Japanese name:

パンドラ

The woman forever destined to unleash evil on Earth. Pandora is the guardian of Hades' soul and his flesh sister in the 20th century. At a young age, she opened the forbidden box that was sealed by Athena and released Hypnos and Thanatos. She was told that Hades would become her brother and she must protect him until the advent of the final battle. In exchange, they would grant her eternal life. She commands the first wave of Specters to attack the Sanctuary in the name of Hades in the final arc of the manga. She was given a necklace that allows her to travel through different realms, and she has a complex relationship with Ikki due to their past regarding Shun. As Hades's sister, she was his slave and was unable to see fully in color but, after seeing Ikki's iron will, she regained her sense of color and her lost memories. Because she gave Ikki the necklace, she was deemed a traitor and killed by Thanatos.
Pandora also appears during her 18th century incarnation fulfilling the role given to her as destiny.
