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 was serialized in Kodansha's shōnen manga magazine Weekly Shōnen Magazine from November 2016 to June 2025, with its chapters collected in 25 tankōbon 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.
