It is year 93 of the Sand Exile, but the implications of that calendar are only now sinking in for Chakuro. Imperial soldiers from the Allied Empire have appeared out of nowhere with orders to kill all the “criminals” of the Mud Whale! The Committee of Elders knows why this is happening but still won’t explain it to the young Marked of the island. And the elders would rather see the Mud Whale sink forever to the bottom of the Sea of Sand than leave them all at the mercy of the empire. -- VIZ Media

The promised land of Amonlogia has turned out to be a nightmare for the people of the Mud Whale. Suou and the Unmarked are being held hostage, and in order to save them Ouni and Chakuro agree to become captive soldiers for the duke. A battle is inevitable as Orca’s forces draw ever closer, but the duke has a far darker mission in mind for Ouni—one that will rock the very foundations of Amonlogia! -- VIZ Media

Lykos and Ouni have been captured by Orca, but instead of organizing a rescue, Suou has ordered the Mud Whale to set sail for their new homeland.

But Orca has just declared independence from the empire, and any rescue attempt will end up right in the middle of his cataclysmic plans! -- VIZ Media

The Mud Whale is in dire trouble. In four days, the imperial apátheia soldiers will return to destroy it and its inhabitants. But the Committee of Elders would rather kill everyone on board than wait for the “mercy” of the empire, and the fighters of the island will do the elders’ bidding without a second thought. Now Chakuro and the other children are forced by circumstance to rebel against the adults in order to save their home and their lives. -- VIZ Media

The promised haven of Amonlogia is closer than ever, but the dark history of the Mud Whale still poses a terrible threat to its people. Somehow, learning the truth about the past has freed Ouni’s thymia from any constraint, and he is forced to lock himself away to avoid hurting the others. But even with that precaution, his very presence is a danger to his people as Orca mounts an expedition to capture the daímonas and kill everyone else! -- VIZ Media
