After parting ways at the end of her decade-long journey with the hero Himmel, the elf mage Frieren sets out again, this time to understand the friends whose lives passed so much faster than her own. These five original stories run alongside the events of the main series, following Frieren and her apprentice Fern together with companions Stark, Lawine, and Kanne. The light novel fills in side moments the main Sousou no Frieren story never had room for.
