Children of the Sea, Vol. 04

Jim, Dehdeh, and Ruka's mom finally track down Anglade's yacht, but neither the rouge scientist nor Umi and Ruka are on board. All that remains is a cryptic invitation to Jim. While Jim tries to figure out the game his ex-colleague is playing and Kanako dives into memories of her daughter Ruka, the strange sea-changes continue around the world.
