Sousou no Frieren › Season 1

Chapter 13 — Episode 13

The episode begins 29 years after the death of Himmel the Hero, in the Alt Woods of the northern lands, where Frieren's party encounters Sein, a village priest. Sein reveals that as a child he dreamed of becoming an adventurer alongside a close friend, but declined the invitation when it came and has regretted it for ten years. He was in the forest gathering wild herbs for his village's upcoming harvest festival when he crossed paths with the group. Then, during the harvest festival, Stark participates in a gambling game and loses all his belongings to the village chief, leaving him stripped down to his underwear. Frieren approaches Sein and invites him to join the party, but he refuses, claiming it is too late for him. In a key parallel moment, a flashback reveals that Frieren herself once told Himmel it was "too late" for her to join his quest to defeat the Demon King — mirroring Sein's own hesitation. Frieren tells Sein bluntly that she dislikes him precisely because he reminds her of her past self. Finally, rather than backing down, Frieren's declaration of dislike only strengthens her resolve to recruit Sein, and she insists he will join the party regardless. Sein ultimately agrees to travel with the group partway, revealing that his true goal is to find his old friend who became an adventurer. The episode ends with Sein officially joining the party and departing the village as the children bid him farewell, with Sein asking where the group is headed — and Frieren answering simply: "Heaven."
