The official Twitter account of Abi Umeda’s Children of the Whales manga has announced that the series will end its serialization in its next chapter, which will launch in the February 2023 issue of Akita Shoten’s Monthly Mystery Bonita magazine on January 6, 2023.
The manga is described as:
In an endless sea of sand drifts the Mud Whale, a floating island city of clay and magic. In its chambers a small community clings to survival, most dying young from the very powers that sustain them.
Chakuro is the Archivist for the Mud Whale, diligently chronicling the lives and deaths of his people. As one of the saimia wielders, whose life spans are cut short by their own magic, he knows his time is limited and is determined to leave a better record than his predecessors. 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.
Umeda launched the Children of the Whales manga in Monthly Mystery Bonita in 2013. VIZ Media is publishing the manga in English.
