Asherah is a Semitic mother goddess who was the wife of the chief god El. She is commonly referred to as the 'Queen of Heaven', whose worship, in the Old Testament, was vehemently opposed by the prophet Jeremiah.
"A Semitic goddess who was the one to bring fertility to the Babylonian lands. She is known as the mother of the gods. It is believed that in Phoenicia, she became Astarte."
—Shin Megami Tensei: Strange Journey Compendium
Asherah appears in Sector Fornax as the last of the revived Demon Kings that rise again to kill the protagonist. Early in the level, Asura, her earlier form, appears as an invisible demon which cannot be detected by the Demonica; after the events of Jack's Squad HQ (and by proxy, the defeat of Moloch, Orcus and Mithras), the three forma necessary to upgrade the Demonica's Enemy Search System are gathered, allowing the protagonist to strike back and force Asura to the lower levels of Fornax to continue the battle.
However, Asura crashes down from the ceiling and releases his true shape as Asherah. Her battle strategies are very similar though very much strengthened; she still will use Asura Rage, now dubbed Asura Roga, and other moves designed to inflict the Rage ailment. After her defeat, she will cry in shame to Mother Tiamat as she succumbs to death. After which, she can be obtained by using a Special Fusion between Asura and Valkyrie.
Asherah is faced in the New Game Plus Challenge Quest, Ishtar, Goddess of Harvest. Found southeast in the Tokyo - Bay Area, she is one of the demons whose soul originates from Ishtar. Minako obtains her soul upon Asherah's defeat.
