The third season of the anime series ‘Mushoku Tensei: Jobless Reincarnation III’ is set to broadcast its 13th episode, titled ‘Diary,’ on September 20, 2026. This episode marks a significant and intense narrative shift as it adapts the contents of the diary left by an older version of the protagonist, Rudeus Greyrat.

The episode depicts a series of tragic events, beginning with Roxy Migurdia contracting the fatal ‘Magic Stone Disease.’ The narrative follows Rudeus’s desperate attempts to save her, which lead to further loss, including the death of Cliff and the eventual passing of Roxy. The story further explores Rudeus’s descent into despair and alcoholism, as well as the tragic fates of other key characters like Sylphiette and Nanahoshi.

Viewers have reacted strongly to the upcoming episode, noting the heavy emotional weight and the ‘cruel’ nature of the plot developments. The episode will be available on TOKYO MX, BS11, and streaming services such as ABEMA and d Anime Store.
