Histoire
The Senmanjoutou Touharoku is a grand ritual to save the world from its destiny of ruin. Challenging the conquest of the giant tower, woven from spiritual arts and gears that manifest every night, is the special agency under the direct control of the Imperial Family, Yaeyamabuki... commonly known as the Yaebuki Kikan. To prevent terrorism by an occult group, the twin ritualists Akane and Aohi end up joining forces with a girl from the Imperial Capital’s security force, Matsurika.
