To Your Eternity Watch Order: Three Seasons, No Films or OVAs
Three TV seasons and nothing else: 20, 20 and 22 episodes, with dates from ANN and what changed between them.
Watch the three seasons in order: season 1 (20 episodes), season 2 (20 episodes), season 3 (22 episodes). There are no films or OVAs to slot in. The studio changed after season 1, from Brain's Base to Drive, and season 3 added Studio Massket alongside Drive, so the change in look is expected and does not mean anything was skipped.
Everything, in order
| Order | Entry | Length | Aired in Japan |
|---|---|---|---|
| 1 | Season 1 | 20 episodes | April 12 to August 30, 2021 |
| 2 | Season 2 | 20 episodes | October 23, 2022 to March 12, 2023 |
| 3 | Season 3 | 22 episodes | From October 4, 2025 |
Season 1
Brain's Base made the first season under director Masahiko Murata. ANN's episode list runs from "The Last One" on April 12, 2021 to episode 20, "Echoes," on August 30. ANN says it premiered on NHK Educational after a delay: it was "originally slated to premiere in October 2020, but it was delayed to April 2021" because of COVID-19.
Season 2
Drive took over, with Kiyoko Sayama directing, according to ANN's encyclopedia entry. ANN's episode list runs from "Infatuation Reborn" on October 23, 2022 to "End of an Era" on March 12, 2023. ANN's report that day confirms "the second season's 20th and final episode aired in Japan on Sunday," and that the official account announced a third season continuing into the "This World" arc.
Season 3
The third season debuted on October 4, 2025 on NHK General, with Sōta Yokote directing at Drive and Studio Massket and Sayama as chief director, ANN reports. It continues the "This World" arc, which ANN says the manga began in January 2023; the manga ended in June 2025. The official story page lists synopses for 22 episodes, matching ANN's encyclopedia entry. Neither lists a fourth season, and we have not found an official statement on whether this season adapts the manga to its end, so this guide does not say.
Where to watch in English
ANN reports that Crunchyroll streamed the first two seasons, with an English dub of season 2, and is streaming season 3 with a same-day English dub. Availability varies by region and changes over time.
