### Summary
Based on the source material provided, here is a summary from an expert manga analyst. \#\#\# \*\*Overall Synopsis\*\* In a post-apocalyptic world submerged by a 70-year monsoon, humanity survives in floating cities while contending with monstrous, mutated sea creatures known as “leviathans.” The narrative follows siblings Bota and Lita Ma, who embark on a desperate journey after Lita contracts a mutating disease from a powerful sea demon. Guided by their guardian, the skilled harpooner Kana, their quest for a cure is perpetually derailed by the violent legacy of their late father, the legendary harpooner Teon Ma, forcing them to confront threats that are both monstrous and deeply human. \#\#\# \*\*Key Characters\*\* \* \*\*Bota Ma:\*\* The younger sibling who begins the story as a vulnerable child. Following the traumatic murder of his father and a significant multi-year time skip, he matures into a capable young warrior who mirrors his father in appearance and skill, eventually wielding his sword. \* \*\*Lita Ma:\*\* The older sibling whose infection with a mutating disease serves as the catalyst for the central plot. Her cure is the primary objective, though the mission is consistently sidelined by other conflicts. \* \*\*Kana:\*\* A highly skilled harpooner who lost her own parents to a sea demon. She acts as the guardian and mentor to Bota and Lita, having raised and trained them for years. Her character design is noted as a source of recurring "fanservice" controversy among readers, creating a tonal clash with the story's grim atmosphere. \* \*\*Teon Ma:\*\* The deceased father of Bota and Lita, a legendary harpooner whose past actions and heroic sacrifice cast a long shadow over the present. Conflicts frequently arise from antagonists seeking vengeance against him by targeting his children, and his legacy is a central driving force of the narrative. \#\#\# \*\*Narrative Progression and Major Arcs\*\* The story arc begins with the siblings' quest for a cure being violently interrupted by the murder…
