According to classical mythology, Isis was the daughter of Geb and Nut, sister of Nephtys and Set, sister-wife of Osiris, and by him mother of Horus.
She is the Egyptian goddess of fertility and domestication and member of the Heliopolitan race of gods.
In the most known myth, she and her sister Nephthys gathered the pieces of Osiris body, slain by their brother Set, and brought him back to life.
Isis, her husband Osiris and her son, Horus were imprisoned for many years in a pyramid that lied deep beneath the Earth. It was her own brother, Seth that put her and her family there so that he may rule the other-dimensional city of Heliopolis without opposition. From within, they were eventually able to cause it to materialize on Earth in the Twentieth Century and Isis along with Osiris and Horus were able to use their powers to contact Odin, ruler of Asgard. Seth had said that the only way they would ever be free is if their ancestor Atum-Re returned to Earth, so the three captives made Odin believe that he was Atum-Re through the Ceremony of Rebirth. The son of Odin, the mighty Thor wanted his father to be released from their spell and agreed to travel to the city of Heliopolis to face Seth with them. On Heliopolis, Seth’s armies were defeated and he was cast out of the city leaving Osiris to reclaim his throne.
In Persona 3 Io is the ultimate Persona of Yukari Takeba.
