Yaebuki Kikan: Senmanjoutou Touharoku

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. Standing in their way are the evil dragon Nanada, who obstructs the tower's conquest, and its followers; the citizens harboring resentment toward the controlled society; and finally, the Princess of Ruin who pulls all the strings. The bond between the boys and the girl, blooming amidst a desperate struggle, eventually becomes a blade that wounds them as well. "In a fading world, the flowers that resist and bloom to their end are truly beautiful." (Source: Dengeki Bunko, translated)
