# To Your Eternity

To Your Eternity (Japanese: 不滅のあなたへ, Hepburn: Fumetsu no Anata e, lit. "To You, the Immortal") is a Japanese manga series written and illustrated by Yoshitoki Ōima. It has been serialized in Weekly Shōnen Magazine since November 2016, with individual chapters collected by Kodansha in 23 tankōbon volumes as of November 2024. The story is about an immortal being, Fushi, who takes on multiple forms and freely utilizes their respective natural abilities at will, including that of an abandoned white-haired boy and his white wolf, in order to further evolve and stimulate as it learns what it means to be truly human over the decades and centuries.
Ōima, inspired by her own grandmother's death, aimed to write about survival and the character Fushi, who initially is an emotionless stone but gradually develops a self and personality as a result of interacting with humans. In contrast to her previous work, A Silent Voice, To Your Eternity puts little focus on the characters' past but instead upon their future.
In North America, the manga is licensed by Kodansha USA for a digital and printed English release. An anime television series adaptation of the manga, produced by Brain's Base, aired from April to August 2021 on Japan's NHK Educational TV; a second season produced by Drive aired from October 2022 to March 2023. A third season has been announced.
To Your Eternity has received acclaim in Japan, earning many awards and generating major sales. Critical response to the series debut was very positive, based on the emotional focus on the villagers and Fushi to the point of often earning perfect scores. Fushi's continuous character arc was praised while Ōima's artistry enjoyed critical acclaim due to its detailed facial expressions and environments.

## Plot
### Part one

An otherworldly being called the Beholder creates a white orb (later named Fushi by a rambunctious young girl). Fushi takes on the form of a rock, then a dying arctic wolf. Fushi meets a white-haired boy living alone who mistakes him for his pet wolf, Joaan. After the boy dies, Fushi takes his form. He travels to the land of Ninannah, and meets a young girl called March, who was chosen as a sacrifice to a large white bear named Oniguma. March names Fushi and teaches him the rudiments of speech, and how to use his hands. Fushi defeats Oniguma, and he, March, Parona (an older sister figure to March), and the elderly woman Pioran, are taken prisoner by Hayase, to Yanome. They escape, but young March is killed protecting Parona and becomes a spirit. Fushi part ways with Parona and leaves Ninannah to escape Hayase, who is determined to control Fushi.
Accompanying Pioran, Fushi begins to speak like a child. As they travel to Takunaha, they are attacked by a plant-like being that can steal Fushi's forms and memories, a Nokker. Fushi kills it, regaining his memories. In Takunaha, Fushi meets a boy named Gugu, who was disfigured in an accident after saving Rean. Gugu saves Fushi from another Nokker, and Fushi, Gugu and Rean become friends. For four years, Fushi refrains from transforming or creating objects in order to live as a human. A Nokker attacks and Gugu was killed in the process while sacrificing himself to save Rean, who becomes a spirit like March. Fushi leaves Takunaha, paranoid of Nokker attacks, followed by Pioran.
Hayase pays a girl named Tonari to lure Fushi and Pioran onto a prison ship to Jananda island. Fushi enters the island's gladiatorial tournament. In the final round, Fushi faces Hayase, who reveals she killed Parona, assuming her form. An enraged Fushi is defeated by Hayase, who captures and attempts to rape him. Tonari and her friends come to try and save him, but at the same time, Nokkers attack the island, and three of Tonari's friends are killed. Fushi kills the Nokkers, and leaves the island with Hayase, abandoning her to die in the ocean, where she is attacked by a Nokker. Fushi reunites with Pioran and travels to an uninhabited island, but she develops dementia. Before her death, she asks the Beholder to have herself reborn as something useful to Fushi, a horse that Fushi later acquires.
Fushi remains on the island for forty years, until Nokkers begin attacking humans off the island. As he prepares to leave, he meets Hisame, the nine-year-old granddaughter and reincarnation of Hayase. Hisame's left arm contains the Nokker which had merged with Hayase. The two travel to the site of the Nokker attack, where they meet the grown Tonari and Sander. Hisame tries to kill Tonari, and is wounded herself, but escapes. Tonari dies in front of Fushi, and becomes a spirit. Fushi rescues Hisame and refrains from killing the Nokker in her arm after she agrees to leave him. For the next two centuries, Fushi avoids extensive human contact, and is regularly visited by the obsessed Hayase's reincarnations and descendants; one of which is a male named Kahaku. They establish a religious cult called the Guardian Force, worshiping Fushi and opposing the Nokkers. After rival religions begin denouncing Fushi, Kahaku removes Fushi from his solitude to further improve his image.
The two are captured by Prince Bonchien, who had been instructed by Tonari to find Fushi. Bon lends his princely approval to Fushi and the Guardians, becoming a target for those opposed to Fushi. Bon witnesses Fushi resurrect a dead princess, but hides the fact from Fushi. Fushi is arrested by another kingdom and forced to demonstrate resurrection, but fails. Both Bon and Fushi are imprisoned, with Fushi encased in solid iron. Fushi escapes and rescues Bon, faking his death. The Nokker in Kahaku's arm warns that the Nokkers will attack the large city Renril in one year. Bon and Kahaku gather allies and warn the city, while Fushi further develops his ability to create objects from nothing.
In disguise as Booze Man, Fushi destroys and recreates buildings in Renril as extensions of his body. Hundreds of Nokkers attack the city, and during the battle March is accidentally resurrected. Three of Bon's allies are killed, and Bon tells Fushi they can return to life. Fushi uses them to defend the city, resurrecting them where needed. As the battle continues, Kahaku's Nokker attacks Fushi, returning him to his original orb form. Bon kills himself near Fushi, giving him his form. Able to see the spirits of his friends, Fushi remembers them and returns them to life, and the battle is won as Fushi regains strength. Kahaku leaves the city with his Nokker, and later kills himself and his Nokker, but not before expressing his strong love for Fushi.

### Part two

Fushi tells his friends he will make the world peaceful, and resurrect them after he has done so. He sleeps and spreads his body across the planet, to stop the Nokkers from returning. Fushi's friends live their lives and all die as Fushi sleeps. After 600 years, Fushi's body encompasses the entire planet, now at a modern level of technological advancement. During his sleep, the Nokkers become microscopically small, secretly living inside of and controlling human beings. Kahaku's Nokker lives in the brain of Mizuha, the eighteenth reincarnation of Hayase, and this Nokker leads the others in preparation for Fushi's return.
After awakening five centuries into the modern era, Fushi resurrects the eleven spirits following him, including his closest friends March, Gugu, Tonari Dalton and Bonchien. The Beholder transforms himself into a twelve-year-old boy, calling himself Satoru. Fushi meets a boy named Yuki, and Mizuha, who falls in love with Fushi, being Hayase's eighteenth reincarnation. Mizuha murders her mother, but she returns to life without Fushi's involvement, alerting him to the Nokkers' return. As he learns that the Nokkers are now living peacefully among humanity, Fushi becomes confused about what to do. He attempts to fight the Nokkers on his own, but Hayase's Nokker launches an attack on Yuki's school.
Hayase's Nokker is ultimately killed, and its organization collapses, but Nokkers continue living among humans. Satoru offers Fushi omnipotence, but he refuses. Before losing his memories Satoru reveals that he created the world out of boredom, then wanted to die in his creation, leaving Fushi to watch over it. After six decades, knowledge of Nokkers has become commonplace, Yuki dies, and Fushi leaves Yuki's home with his resurrected closest friends.

## Production

Manga artist Yoshitoki Ōima conceived the title To Your Eternity after learning that her sick grandmother was going to pass away. At the outset, she was only certain of the title's nuance, but could not arrive at a decision. With the encouragement of colleagues, she eventually chose To Your Eternity. The decision to give the manga a fantasy setting was taken for the freedom it afforded, with supernatural beings offering unusual possibilities. She compares To Your Eternity to her other works, and states that, while A Silent Voice focuses on characters in the present confronting their past, To Your Eternity focuses on the future. She also mentions exploring the theme of death in Mardock Scramble, A Silent Voice and To Your Eternity. The character Fushi originated from Ōima's work in primary school, although the setting changed before the series started. Fushi was originally to be female, but a colleague suggested a male protagonist for a different appeal. Ōima wanted to make the protagonist neutral, and said she prefers neutral female characters. Each volume cover represents a character's dream such as the first one, which depicts the unnamed youth finding freedom. According to Oima, Fushi does not want to forget the people he meets on his journeys.
Characters featured in the series are based on real life personalities. For example, Pioran reminded Ōima of her deceased grandmother. She furthermore expresses some guilt for having characters die. There are approximately 13 characters that are greatly affected by Fushi and which, before the series' beginning, would lead Ōima to the title, "Ash Swords of 13 People" (『13人の灰剣』), before being replaced by "To Your Eternity". When it came to drawing, March was Ōima's favorite character due to her short stature. Furthermore, Ōima says she likes drawing children in confined places.
The overall setting is that of a main character being "a boy who knows nothing". Ōima wanted the reader to find themself, like Fushi, in this situation where they do not know anything. It is for this reason that she did not give prominence to any character other than the hero. A common theme portrayed in the manga is death and immortality. To reinforce the blank slate themes, she decided to create a white universe, which was how she obtained a snowy landscape. As characters living in this snowy region are not part of an indigenous population, she decided not to depict them as, for example, Inuit. For research, she watched several documentaries in order to learn how to make the boy look like he was living in a world of "survival", with limited resources and skills. To accomplish this, she had to think deeply about what was practical under such difficult circumstances. March was created to be talkative and balance the quiet ones. The manga presents the climate, disease and the polar bear as obstacles to the human will. Ōima elaborates that people have to live with these challenges, and it is to show how to overcome them that she included them in the scenes.

### Adaptation

Director Masahiko Murata [ja] expressed surprise when first reading the manga series, initially believing the young villager would be the lead character rather than Fushi. He felt that the themes Ōima was approaching were thought-provoking, which he found challenging. Murata stated that, as minor parts of the manga were changed, the anime would stay true to the original printed version. The official Twitter account of the anime series stated that the main theme presented through March (and later Fushi) was the notion of growing into adulthood.
In casting the actors, Reiji Kawashima's voice quality was befitting for Fushi—from his point of view. "The Observer", played by Kenjiro Tsuda, is a narrative role that was not all that involved in the story due to Murata's view that Tsuda's voice was "cool". The first episode only had two voice actors: Kawashima and Tsuda. The former expressed relief when working as he felt that Tsuda was a friendly person. Tsuda felt that Kawashima was a passionate actor, exemplified by his early arrival for each episode's recording session. Kawashima thought his character to be exhausting based on his varied experiences, while Tsuda felt Fushi was too mysterious. Rie Hikisaka, who plays March, enjoyed Kawashima's work and his interactions with Pioran. For the sixth episode, Kawashima expressed difficulty portraying Fushi's lines due to the fact that the character was learning how to speak. Ryoko Shiraishi commented that while she enjoyed voicing Gugu, the character's fluid personality made the work more challenging.

## Reception
### Manga

The first collected volume of the series sold 29,288 copies, ranking 17 on the weekly Oricon manga chart. Its second volume ranked 34, selling 22,565 copies in its first week, while its third debuted at 41 with 20,445 copies sold.
The manga was nominated for the 11th edition of the Manga Taishō awards in 2018 and it managed to gain a total of 47 points. In 2018, Ōima won the Daruma de la Meilleure Nouvelle Série at the Japan Expo in Paris, France for To Your Eternity. In May 2019, it won the award for Best Shōnen Manga at the 43rd annual Kodansha Manga Awards, alongside The Quintessential Quintuplets. In both 2018 and 2019, Anime News Network listed it as one of the best series for young readers. The first five volumes were listed by the American Library Association as one of the best manga series written for a young audience in 2019.
The manga's narrative and setting have been praised by critics like Otaku USA due to its multiple fantasy and drama elements. However, he felt the story provided in the first volume lacked the emotional impact from the mangaka's previous work, A Silent Voice. Two reviewers from Anime News Network (ANN) and one from UK Anime Network gave the first volume perfect reviews, impressed by the narrative's depth in exploring the multiplicity of characters as well as how the first chapters handled the lonely youth who met Fushi in an Ice Age-like area. Two other writers from ANN wondered whether the new chapters would carry forward the emotional impact of the first. Anime UK News was engaged by the manga's first chapter based on the characterization of the unnamed villager rather than by Fushi. As the manga progressed, Fushi's character arc was the subject of praise as he was closer to acting like a human in contrast to his nearly emotionless introduction. As a result, writers felt the tone of the series was still tragic, thanks to the handling of this character. Manga News furthermore enjoyed the series' time-skips as Fushi's immortality allowed him to blend in with newer, more modern scenarios.
The critical response to the artwork was mostly positive. Anime UK News praised the way Ōima drew the pages, by giving the characters detailed features and the way its settings were presented. Similarly, Manga Mexico writer Tania Ávila praised the artwork—especially in the later chapters of the first volume. Fantasy Mundo noted that the drawings helped to further detail the characters and improve their emotional value. The Fandom Post felt that the artwork "is light on textures and right with detailed backgrounds once the story moves from the snowfields to the forest" and felt that the wildlife was often drawn strangely. UK Anime Network praised the way the backgrounds were detailed and how the author built the characters' emotions.

### Anime

The anime adaptation also attracted positive reactions. IGN listed it among the best anime series of Spring 2021, directing readers to its portrayals of Earth's culture but refrained from further explaining the premise to avoid spoilers. In a Filmmarks survey, To Your Eternity was voted the ninth "Most Anticipated 2021 Spring Anime Ranking". In the website Anime Trendz, the series was often listed as one of the most popular series from 2021. In 2022, the series was awarded Best Drama at the 6th Crunchyroll Anime Awards, and was nominated in the Kids: Animation category at the 50th International Emmy Awards.
Three ANN writers gave the anime's premiere a perfect score, based on the emotional storytelling involving Fushi and the nameless youth, most notably when the latter, initially cheerful and talkative, quickly becomes filled with despair, as he cannot find any other people in the region. Similarly, The Fandom Post gave the series' premiere a perfect score despite having read the manga years before, based on the cast's performances and Utada Hikaru's theme song "Pink Blood" which helped to convey a moving story. James Beckett, from the same site, continued reviewing the anime and while still enjoying the anime, was afraid of it becoming too melodramatic. Comic Book Resources felt the adaptation series was well done and given an appealing soundtrack as the emotional scenes became stronger thanks to the music provided. Critics praised the bonding involving Fushi, March and Parona, noting how heroic they were for each other while providing opportunity for more entertaining scenes. However, March's death in the fifth episode was found to be heartbreaking. Fushi's increasing display of humanity was praised, with the sixth episode giving him enough screentime to become the sole main character. Fushi's fight with Oniguma was also listed as the seventh best anime fight from 2021 by Crunchyroll.
The prison arc, however, was panned by Anime News Network for lacking the appeal of previous arcs as well as the animation being poorly done.
