To Your Eternity
To Your Eternity is a Japanese manga series written and illustrated by Yoshitoki Ōima. It was serialized in Kodansha's manga magazine Weekly Shōnen Magazine from November 2016 to June 2025, with its chapters collected in 25 volumes. 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 produced by Brain's Base aired from April to August 2021. A second season produced by Drive aired from October 2022 to March 2023. A third season produced by Drive and Studio Massket premiered in October 2025.
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
A mysterious being, the Beholder, creates a white orb later named Fushi by a spirited girl. Initially a rock, Fushi takes the form of a dying arctic wolf and meets a lonely boy who mistakes him for his lost pet. After the boy's death, Fushi adopts his form and travels to Ninannah, where he encounters March, a girl destined as a sacrifice to a monstrous bear, Oniguma. March teaches him language and names him. Upon defeating Oniguma, Fushi, March, her protector Parona, and the elder Pioran are captured by the warrior Hayase. Though they escape, March dies shielding Parona, her spirit lingering. Fushi flees Ninannah, evading Hayase's pursuit.With Pioran, Fushi learns speech. En route to Takunaha, they battle a Nokker—a parasitic entity that steals his forms—but reclaim what was lost. There, he befriends Gugu, a disfigured boy who sacrifices himself for Rean, who then becomes a spirit. For four years, Fushi lives as a human until Gugu's death forces him to leave. Hayase manipulates Tonari into luring Fushi onto a prison ship bound for Jananda Island. In gladiatorial combat, Hayase reveals she murdered Parona and impersonated her, infuriating Fushi. Overpowered, Fushi is saved by Tonari's intervention. When Nokkers attack, killing Tonari's allies, Fushi destroys them and abandons Hayase at sea. Reuniting with Pioran, he retreats to an island where her dementia worsens. Before dying, she asks the Beholder to reincarnate as something useful—returning as a horse.
For forty years, Fushi isolates himself until Nokkers target humans again. He meets Hisame, Hayase's reincarnated granddaughter, whose arm harbors a Nokker. After clashing with the now-adult Tonari, Hisame flees. Tonari dies, joining Fushi's spirits. Over centuries, he avoids humanity, but Hayase's descendants—like Kahaku—pursue him, forming the Guardian Force, a cult opposing Nokkers.
Captured by Prince Bonchien, Fushi is coerced into demonstrating resurrection. After escaping, he and Bon prepare for a Nokker assault on Renril. Disguised as Booze Man, Fushi reshapes the city, reviving March accidentally. Three allies die, but Bon reveals they can be restored. When Kahaku's Nokker overwhelms Fushi, Bon sacrifices himself, allowing Fushi to regain strength. Reviving his allies, Fushi secures victory. Kahaku later takes his own life, confessing his devotion.
Part Two
Fushi vows to create a peaceful world and resurrect his fallen companions before entering a centuries-long slumber, his essence spreading across the planet to suppress the Nokkers. Unbeknownst to him, the Nokkers survive by evolving into microscopic parasites, hiding within human hosts. The one that once possessed Kahaku now lurks within Mizuha, the eighteenth reincarnation of Hayase, secretly rallying the remaining Nokkers for Fushi's eventual return.Awakening in the modern era, Fushi revives his eleven spirit companions—March, Gugu, Tonari, Bonchien, and others. The Beholder appears as a boy named Satoru, while Fushi crosses paths with a teenager, Yuki, and Mizuha, who—as Hayase's latest incarnation—becomes obsessed with him. When Mizuha kills her mother, only for the woman to inexplicably revive, Fushi realizes the Nokkers never vanished—they have integrated into humanity. Torn between eradication and coexistence, his hesitation allows Hayase's Nokker to retaliate, attacking Yuki's school.
Though Fushi destroys Hayase's Nokker and dismantles its network, others remain hidden in society. Satoru offers him omnipotence, but Fushi refuses. Before erasing his own memories, Satoru reveals he created the world out of boredom, longing to perish within it—and now entrusts Fushi as its eternal guardian.
Six decades later, with Nokkers widely known and Yuki gone, Fushi leaves with his resurrected friends, continuing his timeless watch.

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", 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 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 was the notion of growing into adulthood.In casting the actors, Reiji Kawashima's voice quality was befitting for Fushifrom 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 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 artworkespecially 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 and nominated for Best Fantasy at the 6th Crunchyroll Anime Awards; it was nominated again in Best Drama for its second season at the eighth edition in 2024. The series was also 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.
