Mermaid Saga (人魚シリーズ Ningyo Shirīzu?) is a series of manga graphic novels in three volumes by Rumiko Takahashi. Two of the stories from the series, Mermaid Forest and Mermaid's Scar, have been adapted as anime OVAs, and all of the tales, except one, were later produced as an anime TV series.
The original manga was serialised in Shōnen Sunday, starting in 1984. In total there are 14 episodes.
The first tankōbon was Ningyo no Mori, named after the third story within it (or Rumic World: Ningyo no Mori in its OVA adaptation.) The second tankōbon, Ningyo no Kizu was then released in Japan, leaving out two stories: "Yasha no Hitomi" and "Saigo no Kao". These stories were not available then the book came out. The serie was re-released in Shinsoban format in 2003. Now in three volumes and with the two episodes "Yasha no Hitomi" and "Saigo no Kao". Later a new edition, in four volumes, with the same 14 episodes were released.
In US the manga was first released in three volumes, called Mermaid Forest, Mermaid's Scar and Mermaid's Gaze. Later in four books, named volume 1-4.
The first OVA, Mermaid Forest, was released in Japan in August 1991 and was distributed by Central Park Media in the United States, there marketed as one of the "Rumik World" anime (along with Maris the Chojo, Fire Tripper, and Laughing Target).
Mermaid's Scar, released in September 1993 has the distinction of being one of the two titles which launched VIZ Media's anime line, VIZ Video. Along with Ranma ½, Mermaid's Scar broke ground for VIZ and set them along the path as one of the leading anime producers in America. Mermaid's Scar is available dubbed only.
In 2003 the animation company Tokyo Movie Shinsha produced a 13 episodes TV series based on Takahashi's short stories as part of the Takahashi Rumiko Gekijō series. All but Mermaid's Gaze were animated. While closely following the story of the original manga (more so than the OVA versions), many of the violent aspects of the stories were toned down. Only eleven episodes were shown on Japanese TV, with the final two episodes (Mermaid's Scar) released direct to video, allegedly because this particular story was too violent for TV. It was released in North America by Geneon.
According to an ancient Japanese legend, mermaid flesh may grant immortality if eaten. However, there is a much greater chance that consumption will lead to death or transformation into a damned creature known as a Lost Soul (or Deformed Ones in the English dub). Mermaid Saga tells the tale of Yuta, an immortal who has been alive for five hundred years. Throughout the series, he wanders across Japan searching for a cure and meets others whose lives have also been ruined by mermaid flesh.

|October 4, 2003|
|In a mountain village, inhabited half by identical young women and half by identical old women, live two unique individuals, Mana, a girl who has just turned fifteen, and Baba (Nanny in the English dub), the old woman who pampers Mana while keeping her shackled in bed. The secret the women keep, even from Mana, is that all the identical women are mermaids and that aged mermaids need to eat young immortal women to regain their youth. Yuta, an immortal human who is now 500 years-old arrives and attempts to find a mermaid. After Baba feeds the flesh of one of the mermaids to Mana, Yuta learns about their ultimate plan for Mana and tells her about it. While trying to stop Yuta and Mana from escaping, the women revert to their mermaid form and are unable to take human form again. Baba, also an immortal human, stays behind as Yuta and Mana leave. Yuta tells Mana that life as an immortal isn't all bad, but he still hopes to become mortal again.|

|In a flashback, Yuta remembers Rin, the daughter of the pirate chief of Toba island, and the ruthless rival pirates of Sakagami island. Isago, the wife of the Sakagami chief, convinces the chief to use his men to hunt mermaids. She also hires Yuta and some other men in a nearby port for the hunt. On Toba, Rin's father is gravely ill, so Rin leads the raiding parties on passing ships, demanding a tenth of their cargo as a toll, but killing no one. Yuta, drowned in a violent storm while mermaid hunting for Isago, washes up on Toba. As Rin places flowers on Yuta's grave the next day, he revives. For a time, Yuta lives and works with the Toba islanders. One day, Isago sees Yuta and Rin in port. Surprised to see Yuta alive, Isago realizes he is immortal and believes he kept the mermaid she hired him to find. She follows them back to Toba and stabs Rin's father, telling Rin that only mermaid flesh can stop him from dying. In retaliation, Rin kills Isago.|

Isago reveals that she has been pregnant for three years by her previous husband, whom the Sakagami islanders killed, and that she needs mermaid flesh so she can finally give birth. A revived Yuta arrives to save Rin. The chief and his men alternately fight Yuta and Rin and eat mermaid flesh. Those who don't die from the mermaid flesh, including the chief, become Deformed Ones. She also tells the chief that she too is a mermaid. Isago runs away and jumps off a cliff into the ocean. Yuta and Rin think Isago did it in desperation, but Isago, now in mermaid form, swims away trailed by two smaller forms. On Toba, Rin's father recovers on his own, without mermaid flesh. Back in the present, Mana asks Yuta how far the ocean goes.|

When they were young, Sawa had given Towa medicine made of mermaid blood to save her from a terminal illness, making her ageless, but Deforming her arm and making her hair turn white.

|Sawa reveals the mermaid's location to Towa to save Mana. Mana revives as they approach the mermaid tomb. Yuta arrives at the tomb and tells Towa that eating mermaid flesh will only complete her transformation into a Deformed One. He also says being immortal was lonely before he found Mana. Towa says immortality or transformation makes no difference and forces a piece of mermaid flesh on Sawa, explaining that Sawa had desired immortality. Too afraid to try it herself, Sawa had experimented on Towa, her identical twin. Then, while Towa had lived in confinement, Sawa had lived a full life. Towa wants Sawa to be immortal, as an old woman or as a monster. Sawa then dies of a heart attack, denying Towa her revenge. Towa tells the others to burn the tomb, the house, and everything in them, including Towa. As they watch the fire burn, Shiina says that he had tried to convince Towa to elope with him when he was young. Towa had refused, saying she had to stay to get her revenge.

The village holds a funeral for her, even though there's no body. Over the decades, Eijiro, Nae's former fiance, buys the village land. In the present, Mana finds one of Eijiro's men beating a girl named Nae. Nae kills the man, but two other men kill Mana. Eijiro, who keeps Nae confined on his estate, realizes Mana is immortal when she revives. Meanwhile, Sokichi, having met up with Yuta, tells Yuta that Nae is still alive unchanged and leads him to Eijiro's house, where Eijiro's men capture them.

He cannot find it, however, because Nae hid the remaining ash to keep her father from finding out that she used it to make the Red Valley. Eijiro looks for the ashes for decades and finally finds it, using it to revive Nae's still pristine corpse in the Red Valley. In the present, Yuta and Sokichi escape Eijiro's men.

- As a main character of the series, Yuta is a 500-year-old immortal. He ate the flesh of a mermaid out of curiosity when his fellow fishermen had captured one, but out of all the fishermen who ate a piece, only Yuta survived. His comrades had either been poisoned or turned into Lost Souls. Yuta was afraid that he would meet the same fate, after nothing happens to him, forgets about ever eating the mermaid's flesh. He takes a wife and lives normally until he discovers that while she grew older as the years went by, he hadn't aged physically since the day he ate the flesh. He hears that a mermaid will be able to help him turn normal again, so he begins his endless travel in search of a way to become mortal. Along his travels, he meets a girl named Mana, another immortal. He rescues Mana from mermaids who were planning to devour her, and she joins him as a traveling companion.

- The female protagonist of the series, she is an immortal and Yuta's companion. She was raised by a group of old women who kept her captive and incapacitated in a hut. In reality, they were mermaids who sought to eat her once she reached adolescence and consumed human flesh in order to regain their youth. She travels with Yuta after he rescues her, and possesses a large sense of loyalty and feelings towards him, but due to her somewhat naïve and spoiled nature, she doesn't seem to truly realize her emotions towards him may be love, or even simple affection (even where Yuta stated she might have been jealous, she doesn't understand what that word means, mistaking the pronunciation for jellosy and asks if it tastes good). She is fifteen when she gains immortality at the beginning of the series.
- Masato (真人 Masato?)
- Voiced by: Makiko Ohmoto (Japanese), Erika Weinstein (English)
- Mermaid's Scar OVA Voiced by: Yuuichi Harada (Japanese), Chris Turner (English)
- A young boy who has been immortal for eight hundred years. He has a face of an angel, but the soul of a devil. Despite his childlike appearance, eight hundred years of loneliness and wandering have turned Masato into a cruel and heartless monster. His first victim to whom he fed mermaid flesh was his original mother eight hundred years ago, who became a Lost Soul. After one hundred years of being adopted by various people and losing them to famine, disease, and war, the boy decides to end this cycle of loneliness and try mermaid flesh again. For the next seven hundred years to come, he would patiently give mermaid flesh to a woman, and have her pose as his mother until she was deemed useless, not caring if they turn into monsters or die from poison, and knowing that he would one day find a true immortal companion. He also managed to take a Nambu pistol from a war and hid it, which he used in his battle against Yuta. In the OVA, it is revealed that his latest mother figure, Misa, gave him the name Masato. He found her during World War II after she had lost her real son in an air-raid. Sixty years later, Yuta and Mana came across Misa and Masato, and after Misa began losing her regenerative powers, Masato set his sights on making his nanny, Yukie, as his new mother-figure. Unfortunately, Yukie turned into a Lost Soul, and Masato turned his sights on Mana. However, after seeing how Mana was devoted to Yuta and brutally attacked Masato for it, the 800-year-old boy gave her up for being a "horrible girl", and set the mansion on fire in an attempt to burn the two to death. He took Misa's car and fled, but plowed right into a truck (off a cliff in the OVA), and was thought to have perished. However, since his corpse was not found, it was implied that he was still out there searching for another mother. Masato is the only character in the entire series known to have lived longer than Yuta, a fact that shocked and horrified Yuta when he tried (unsuccessfully) to use his own 500 years to intimidate Masato.

- Mermaid's Scar OVA Voiced by: Gara Takashima (Japanese), Janyse Jaud (English)
- She lost her husband and child during World War II, and nearly died herself when she met a little boy who offered her a strange piece of meat. The child was Masato and the meat mermaid flesh. At first Misa was happy to have a new child in her life, but she grew afraid of the fact that neither were aging, and became terrified of what Masato was capable of. After escaping from him five years ago, she was taken in by an old man whom she later married. About one month ago, the two were in a boating accident and Misa was thought dead until a week later when she appeared with no wounds. Masato tracked her down and forced her to continue to act as his mother figure. She, in turn, tried to take the mermaid flesh from him to prevent him from feeding anyone else it, but to no avail. Unfortunately, Misa failed to become a full-fledged immortal, as the mermaid flesh's effect began to wear off, and her healing powers were getting slower and weaker. Masato then simply told her that he would find a replacement. She eventually died after being attacked by a Lost Soul which was formerly Masato's nanny, Yukie. Masato shed a tear for her demise before departing.

To prevent her from leaving, Masato gives Yukie a piece of meat in which it turns out to be mermaid's flesh and then she eats it. She didn't become an immortal, however: She transformed into a Lost Soul. After Yuta kills the monster, he discovers that it is Yukie who ate the mermaid flesh by finding her ring lying on the floor. Yuta possesses Yukie's ring during his travels to help him remember Yukie as his friend (in Mermaid Scar OVA, he throws the ring to the ocean in the end).

The blood cured her illness, but her arm deformed that of a Lost Soul's and her hair turned pure white. While she didn't age on the outside, her insides continued to age at the same rate as a mortal's. When Towa's father learned of what Sawa did to her, he had Towa locked up in a cell underneath the house and never allowed her to come out. Sawa lived a normal life: She wed and had a child while Towa lived alone with no visitors except for Shiina. Her deformed arm caused her terrible pain, so she asked Dr. Shiina to cut off the arms of dead girls and re-attach them onto her. But after a few years every arm also became deformed and the pain came back. After their father died, Sawa released Towa from her cell. Towa threatens to replace her body with Mana's unless Sawa reveals where Mermaid Hill is. Once Towa found the mermaid, she tries to force Sawa to eat its flesh to fulfill her revenge, but Sawa dies of a heart attack. Robbed of her revenge, Towa joins her sister in death and asks them to burn Mermaid Hill and everything associated with it.

- Big Eyes (大眼 Ōmanako?)
- Voiced by: Daisuke Gōri (Japanese), Kyle Hebert (English)
- He was once a mortal, but he ate the flesh of a mermaid corpse he found lying on the beach in the hopes that he would gain immortality. When he woke up, he saw that his village has been destroyed and everyone - including his family - had been murdered. The flesh had transformed him into a Lost Soul, though not fully as he can speak and has human feelings. He had apparently lost control of himself after transforming and done the deed himself. The transformation had caused his eyes to swell so he was called "Big Eyes" from then on. He is without company for a long time until Mana came along. He finds her just reviving next to a dead Yuta at the bottom of a cliff they fell from. He takes her to his cave and feeds her after she wakes up. He wants Mana to stay with him for company as she is the first person to treat him kindly since his transformation. Upon finding Mana and Big Eyes, a hunter who lost his left eye to Big Eyes 40 years ago attacks him. The attack causes Big Eyes to lose control of himself and revert to his Lost Soul side. Mana tries to protect him, but Yuta and the hunter have no choice but to kill him in the end. As he lay dying, he calls out Mana's name with his last breath. Yuta tells her that this shows Big Eyes died as a human.

With her father dealing with Yuta, Natsume is now unprotected from the monk, who is able to rip out her liver. Natsume saves Yuta from getting killed, but her father jumps from a cliff with her in his arms. Her father died from the fall, but Natsume was able to live a little bit longer. She tells Yuta a good-bye and she says that she'll always be with him in his journey, and then she returns to bones.
