Amaterasu is the Japanese sun goddess who rules over the High Plain of Heaven. Her name means "she who illuminates the heavens." She was born from Izanagi's left eye. The most famous myth involving her took place when her brother Susano-o attacked her temple in a drunken rage and killed several of her priestesses. Distressed by this, Amaterasu fled into a cave and darkness fell on the world. Ultimately, the other gods lured her out of her hiding place by placing a mirror next to the cave entrance and began to cheer and yell due to the antics of Ame no Uzume. When Amaterasu peeked out to see what the commotion was, she was told there was a new god and was directed to look at the mirror. Having never seen her own reflection before, she was fascinated by what she saw and was lured out of the cave, returning light to the world. Amaterasu is also known as the ancestor of the Imperial lineage.
In Kojiki, her name is unified to be "Amaterasu-Omikami" (天照大御神). In Nihon Shoki, she is more often addressed by her full title of "Amaterasu-Sume-Okami" (天照皇大神), or alternatively "Sume-Omikami" (皇大御神), which literally means the "Great Imperial Deity." In the medieval period, Amaterasu was often called "Tenshô Daijin," its on'yomi reading.
Amaterasu is the highest leveled Gaean demon and appears exclusively in the PC release of the game. Amaterasu can be fused with Missionary and Crusader in order to create Dainichi Nyorai.
