Caster's True Name is Circe (キルケー, Kirukē?) . She is the daughter of the sun god, Helios, and is also the aunt of Medea. She appears in the epic poem of Homer - the "Odysseia". A famous witch from the mythology of Aeaea Island. A demigod that presides over the moon and love, related to the genealogy of the goddess Hecate. A rikejo that has the mixing of a magic drug that brings about various effects and mutations as her forte. Although she would show a warm welcome to the human men that visited her island with by entertaining them with a feast, she turned them into lions, wolves and pigs upon growing bored on them. Her older brother is Aeetes (the King of Colchis・father of Medea). Her younger sister is Pasiphae (wife of Minos, King of Crete・mother of Asterios). When the Sea God Glaucus sought a love advice from her, she grew jealous after being rejected by Glaucus once they had an illicit affair and ended up turning his beloved maiden Scylla into a monster. Said Scylla would later devour six of Odysseus’ subordinates. The hero Odysseus stopped by Aeaea Island on his way back to his homeland and was offered a poisoned wheat porridge by Circe, but she took a liking of him in the end as a result of breaking her magic with the divine protection of Hermes. When Odysseus departed, she gave him useful advice for avoiding hardships in his travel.

Fate/Grand Order (Game)
Fate/Grand Order is an online, free-to-play role-playing mobile game developed by Delightworks using Unity, and published by Aniplex. The game is based on Type-Moon's Fate/stay night franchise, and was released in Japan on July 29, 2015 for Android, and on August 12, 2015 for iOS. The game is centered around turn-based combat where the player, who takes on the role of a "Master", summons and commands powerful familiars known as "Servants" to battle enemies. The story narrative is presented in a visual novel format, and each Servant has their own scenario which the player can explore. In 2015, the Chaldea Security Organization draws on experts of both the magical and mundane fields to observe the future of mankind for possible extinction events. Humanity's survival seems assured for the next century—until the verdict suddenly changes, and now eradication of the species awaits at the end of 2016. The cause is unknown, but appears to be linked with the Japanese town of Fuyuki and the events of 2004 during the Fifth Holy Grail War. In response, Chaldea harnesses an experimental means of time travel, the Rayshift technology. With it, Ritsuka Fujimaru (a young man or woman, depending on the player's choice of gender) was newly recruited to the organization, and a mysterious girl named Mash Kyrielight, can travel back to 2004 and discover how to save humanity. A grand order to fight fate has been declared—an order to change the past and restore the future.[12] Following the events in Fuyuki, Ritsuka Fujimaru and Mash Kyrielight must restore the Foundation of Humanity by retrieving powerful Holy Grails.
