In the world of The Grave Robbers' Chronicles, the Iron Triangle of Wu Xie, Zhang Qiling, and Wang Pangzi accidentally triggers an ancient mechanism related to the secret of “immortality” while continuing an exploration of the Seven-Star Lu Palace. At the same time, Shinku, a doll from Rozen Maiden, is driven into a rift in time and space by a rival doll amid the cruel competition of the Alice Game. She falls into the tomb where Wu Xie and the others are. At death’s door, Shinku uses the Rosa Mystica to make a pact with Wu Xie, whose heart is “pure,” sustaining her existence with his life force. Their bond not only lets Shinku move through another dimension, but also infuses Wu Xie’s blood with the doll’s “rose power.” He can sense the “emotions” of mechanisms and traps, and briefly awaken Shinku’s battle form in moments of danger.
As the Iron Triangle ventures deeper into the Xisha Underwater Tomb, the Qinling Sacred Tree, the Cloud Palace, and other sites, Shinku gradually discovers that the mystery of “immortality” in the world of The Grave Robbers' Chronicles is intricately connected to the “Alice Game” of Rozen Maiden. The Queen Mother of the West’s “corpse-eating beetle elixir” and the “Ultimate” behind the Bronze Gate may hold the answer to ending the dolls’ fate. And in his time with Shinku, Wu Xie moves from wariness toward a “nonhuman being” to becoming the one and only “contractor” she can trust. When the secrets of the Zhang Family Ancient Tower are revealed, Shinku must choose between returning to the world of Rozen Maiden to continue the game and staying by Wu Xie’s side to defy fate. Their pact will determine the survival of both worlds.
