Based on a shonen manga by Kanehito Yamada, Frieren: Beyond Journey's End is a fantasy anime set decades after a group of heroes saved the world by defeating the Demon King. One member of the group was Frieren, a long-living elf. Due to elves outliving humans by hundreds of years, Frieren did not fully appreciate the time she had with the rest of the group. Alongside a few young characters, Frieren goes on a new journey that retraces her former group's heroic adventure.
