For an anime based on a shonen manga, Frieren: Beyond Journey's End has been rather unorthodox so far. Nevertheless, there's been a lot of charm behind the decision to start this story at the end of an adventurers' ten-year quest to defeat the Demon King that previously plagued the land. Frieren proves that it's still full of surprises and that this adventure is far from over and truly only just getting started. Frieren's narrative follows the long life of its elf mage protagonist, Frieren, who instead provides viewers with an introspective trek. Frieren's journey is one that's filled with regret and longing memories. She not only has to say goodbye to her friends, but Frieren is also left to figure out what to do with her life during times of peace.
