A tourism‑promoting anime set in Ogaki City, Gifu Prefecture, draws from the novel Oam Monogatari. The story follows Oam, daughter of Yamada Kyoreki—a retainer of warlord Ishida Mitsunari—who matures amid the Sengoku period. It provides a rare glimpse into the life of a noble young woman during wartime.
The series alternates between past and present, revealing Oam"s hardships at Ogaki Castle—later the flashpoint of the Battle of Sekigahara that founded Tokugawa rule—and her nocturnal escape with her mother. The narrative also delves into the political intrigue surrounding Ishida Mitsunari"s faction and the looming threat of Tokugawa Ieyasu, while chronicling Oam's inner struggle between loyalty and longing.
