Children of the Whales #1

This first volume of Abi Umeda's dark fantasy manga introduces readers to the Mud Whale, a massive island drifting through a sea of sand. Its inhabitants, a community of psychic users called Marked, live under the shadow of a deadly secret—their powers shorten their lifespans. When a young archivist named Chakuro encounters a mysterious girl from outside their world, it sets in motion events that challenge everything they know about their isolated existence.
