To Your Eternity (Seasons 1–3)

To Your Eternity (不滅のあなたへ, 2021) is a Japanese fantasy anime series you can watch online on iFILM. Produced by Brain's Base for NHK, the show ran for three seasons and 62 episodes before reaching a complete ending — no cliffhangers left dangling.

The story follows a nameless immortal entity dropped onto Earth with no memory and no purpose. It can copy the shape of anything it touches: first a rock, then a wolf, then a lonely boy living alone in a frozen wilderness. Each transformation comes at a cost. The being — eventually called Fushi, voiced by Reiji Kawashima — begins to understand that living forever means watching everyone else die. Kenjiro Tsuda voices the mysterious Beholder who set Fushi's journey in motion. The narrative spans centuries and dozens of lives, cycling through war, friendship, and grief without ever letting Fushi simply move on.

Based on the manga by Yoshitoki Oima, creator of A Silent Voice, the anime moves at an unusual pace — each arc is nearly a self-contained story, but the connective tissue is emotional rather than plot-driven. Stream all seasons of To Your Eternity online on iFILM.
