THE DRAGON’S CURSE AND RYUU’S RECKONING As fragments of his lost memory return, Ryuu sets out alone to the ominous Seiryukan Hotel—drawn by echoes of the past and his connection to the Amakusa family. But when a string of gruesome murders unfolds, each eerily mirroring an ancient dragon legend, suspicion falls squarely on him. With blood ties linking the victims to his family and Ryuu found at the scenes, the net tightens. Now hunted and isolated, Ryuu must confront his destiny head-on. Meanwhile, Kyuu and the rest of Class Q are faced with their greatest test yet—can their trust, loyalty, and determination overcome the shadow of doubt and uncover the truth behind the killings? The battle between fate and friendship reaches a boiling point as the legend comes to life.
