The next stop for the Children of the Whales anime—which adapts the manga by Abi Umeda and first premiered on TV in Japan back in October—is Netflix. While it was previously just listed for a 2018 launch, the official website has since narrowed that date down to a worldwide debut on March 13.

But the steady pace of their isolated existence on the Mud Whale is abruptly shattered when a scouting party discovers a mysterious young girl who seems to know more about their home than they do…
