To Your Eternity, 24

The doll's true identity is revealed. She set herself a goal, even if it meant becoming a doll: to destroy Kaibara's headquarters in the sky, and to do it for Adee. How will her suicide mission end? While Inmo and the doll learn the history of the laboratory, the rest of their immortal companions are attacked by Kaibara. To save them and end their fateful confrontation with the Beaters, Inmo sets out to find the "omnipotent sphere," the Watcher's legacy that he once refused. The Beaters' plan is revealed, along with the Watcher's entrusted will to Inmo and the fate that awaits humanity.
