Children of the Sea

海獣の子供

Cut off from her summer plans after falling out with her mother and her handball teammates, junior-high student Ruka drifts to the aquarium where her father works. There she meets Umi and Sora, two boys said to have been raised by dugongs and kept under observation for the strange affinity they share with the sea. As marine life around the world begins gathering toward Japan and a light falls into the ocean, Ruka is pulled into the mystery surrounding the brothers and the events tying them to the water.
