Mermaid Saga

Mermaid Saga (人魚シリーズ) is a series of manga graphic novels in three volumes by Japanese mangaka 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 a thirteen-episode anime TV miniseries that ended on a cliffhanger.

History
The original manga was serialised in Shōnen Sunday, starting in 1984. The first tankōbon was Ningyo no Mori, named after the third story within it, or Rumic World: Ningyo no Mori in its OVA adaptation.

This first OVA, Mermaid Forest, was released in Japan in August 1991 and was picked up surprisingly quickly in the United States. It was distributed by Central Park Media and was 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.

Summary
According to an ancient legend mermaid flesh may grant immortality if eaten. However, there is a small chance of that happening, with a much greater chance that the consumer will die or become 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 travels across Japan and meet others whose lives have also been ruined by mermaid flesh.

Main characters

 * Yuta (湧太)
 * Mermaid Forest OVA (English)
 * Mermaid's Scar OVA (English)
 * As the main character of the series, Yuta is a 500-year-old immortal, born in 1480. 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. Kind-hearted and helpful, Yuta has befriended many people who are affiliated with the mermaid's flesh over 500 years, and tried to help them from its curse.

 * Mana (真魚)
 * Mermaid Forest OVA (English)
 * Mermaid's Scar OVA (English)
 * 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). Born in 1965, she is fifteen in 1980, when she gains immortality/longevity and accelerated healing at the beginning of the series.
 * She may have been the model for the undead Priestess Kikyo of InuYasha.

Other Characters

 * Masato (真人)
 * Mermaid Scar OVA Voiced by: 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, 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, Mana and Yuta 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 monster, and Masato turned his sights on Mana.
 * However, after seeing how Mana was devoted to Yuta and brutally attacked Masato for it, the eight hundred years 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 to use his own 500 years to intimidate Masato.

 * Misa (美沙)
 * Mermaid Scar OVA (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).

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.

 * Big Eyes (大眼)
 * 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 imortality. 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.

Using a mermaid's liver for Hangon not only brought Natsume back to life, but also granted her immortality. However, it also caused her to eat the livers of animals and even humans. Many decades later, Yuta meets Natsume while he is questing to find a mermaid. He also meets the monk who has decided to return Natsume to bones. When Yuta meets the monk, he agrees that he'll try to help the situation, but Natsume befriends Yuta and asks if she can come with Yuta on his journey. But her father became angry at this and tries to kill Yuta to prevent Natsume from leaving him. 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.
