Children of the Sea / Daisuke Igarashi

Ruka’s summer isn’t off to a great start. She’s been kicked off the school handball team, she’s not getting along with her parents, and she’s got nothing to do all day. That is, until she meets a mysterious boy named Umi with a natural affinity for the ocean. According to the accounts of others, Umi and his brother Sora were raised at sea by dugongs, making them more accustomed to water than land. At the same time, Ruka’s father, who works at an aquarium, is investigating the sudden disappearances of fish around the world. Things only get stranger when whales, sharks, and other creatures of the deep start showing up in places they shouldn’t be. Could Ruka’s new friends be the cause of these unusual phenomena?
