Demeter (ΔHMHTHP) is one of the Twelve Machine Gods appearing in the Atlantic Lostbelt in Fate/Grand Order. Prior to the Olympian Civil War, Demeter was caring and understanding of her fellow Olympians and humanity. She held a strong maternal love for her daughter, Persephone, holding her close to her heart. However, after being forced to kill her daughter during the war, Demeter fell into madness. She became more callous and indifferent towards humanity as she was forced to live on and serve Zeus.
