The battle for the Mud Whale becomes a deadly rout as the Marked fight to protect their home and their comrades from the invading apátheia soldiers. Meanwhile, Chakuro and the rest of the boarding party have made it safely onto the imperial battleship Skyros, but their mission turns bloody when they reach the thymia-proof chamber at the heart of the ship. How will they destroy the enemy Nous and save the Mud Whale without access to their powers? -- VIZ Media

Chakuro is the archivist for the Mud Whale, diligently chronicling the lives and deaths of his people. As one of the short-lived thymia wielders, 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... -- VIZ Media

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 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 emperor and the great Nous Ánthropos have arrived on the shores of Kívotos! Chakuro tries to stand against the emperor and his terrible plan, but the show of resistance only gets him and Lykos pulled to the bottom of the Sea of Sand. Everyone knows that nothing survives sinking under the sands, but death isn’t what awaits them in them depths—it’s knowledge. -- VIZ Media

Chakuro, Suou and Shuan ventured to the battleship Karcharías to convince Orca to release Ouni and Lykos. But instead of rescuing their friends, they are now caught up in Orca’s plan to destroy the Mud Whale and all its residents! He claims this will unleash an apocalypse and overthrow the Nouses, creating a parallel world where humans will never again feel pain or sadness, but Chakuro and his friends aren’t interested in that kind of future. When words prove useless against Orca’s sophistry, will the team from the Mud Whale be forced into violence?! -- VIZ Media
