In short: Rumiko Takahashi’s Mermaid Saga explores the dark consequences of seeking eternal life. While legend suggests mermaid meat can grant immortality, it more often results in death or a grotesque transformation into a Lost Soul. The series follows Yuta, an immortal wanderer searching for a way to become human again.

The Mermaid Saga, a manga series published between 1984 and 1994, centers on the grim reality of those who consume mermaid flesh. According to ancient Japanese tradition, this act carries a slim chance of achieving eternal life. However, the outcome is frequently fatal or leads to the creation of a Deformed One, a wretched creature known as a Lost Soul. Yuta, the protagonist, has lived for 500 years after eating the flesh, an experience that killed or mutated his companions while leaving him unchanged. Having grown weary of his endless existence, he travels across Japan in hopes of finding a mermaid who can restore his mortality.

During his journey, Yuta encounters Mana, a young woman who was held captive by mermaids. They had bestowed immortality upon her at age fifteen, intending to eventually consume her to rejuvenate their own aging bodies. Yuta rescues her, and the two form a deep, protective bond. Their travels bring them into contact with various individuals whose lives have been ruined by the pursuit of mermaid-derived longevity. These stories often reveal how the desire for eternal life corrupts human relationships, driving characters to commit acts of kidnapping, murder, and obsession in attempts to replace lost loved ones or reverse their own physical decay.

The series, which received the 20th Seiun Award for Best Comic in 1989, uses these supernatural elements to examine the heavy toll of immortality. Whether it is the 800-year-old Masato manipulating caregivers to act as surrogate mothers or the tragic fate of sisters like Towa and Sawa, the narrative consistently portrays mermaid flesh as a cursed relic. These tales illustrate that circumventing natural death does not preserve happiness; instead, it often traps individuals in cycles of trauma and isolation. By the time the stories conclude, the characters frequently discover that the quest to escape mortality only serves to highlight the fragility of the human connections they desperately try to maintain.
