The Great Terrene Empire consists of a thousand worlds in the known Universe. In the search for a place to call home, Humans colonised freely and many worlds even forgot they were part of the Terrene Empire.
The Ryuu Empire spans a third of Pleione, a beautiful Almost Earth world, but to a small girl on the Island Province of Tenshi, none of that means anything. Sakura is content to learn and play amongst the flowers and butterflies of her Father's Castle, worrying only about the twins sharing her mother's body.
However, when the awakening of the Ika-Zuchi-No-Kami threatens her safety, the God Inari sends his chief Kitsune, Maiya, to rescue the child and her pregnant Mother. As the Earth Demons ravage Atamasanshi, Sakura comes up with a plan to lull the demons back to sleep and save her father.
