To Your Eternity is a Japanese manga series written and illustrated by Yoshitoki Ōima. It ran in Kodansha’s shōnen manga magazine Weekly Shōnen Magazine starting in November 2016 and concluding in June 2025, with its chapters compiled into 25 tankōbon volumes. The narrative centers on an eternal entity named Fushi, capable of assuming various shapes and harnessing the innate powers of each form at will—such as those of a forsaken boy with white hair and his loyal white wolf—as it grows and matures by discovering the essence of humanity across vast spans of time.
Drawing from the profound loss of her grandmother, Ōima sought to explore themes of endurance and resilience through Fushi, who begins as a blank, unfeeling orb of stone and slowly acquires identity and emotions via connections with people. Unlike her earlier series, A Silent Voice, this work shifts emphasis away from the characters’ histories and toward the possibilities that lie ahead.
In North America, Kodansha USA holds the license for both digital and physical English editions of the manga. The story received an anime TV adaptation, with the initial season crafted by Brain’s Base and broadcast on Japan’s NHK Educational TV from April through August 2021; the follow-up season, helmed by Drive, ran from October 2022 until March 2023.
