Third season of Mushoku Tensei: Isekai Ittara Honki Dasu.

After the mysterious mana calamity, Rudeus Greyrat and his fierce student Eris Boreas Greyrat are teleported to the Demon Continent. There, they team up with their newfound companion Ruijerd Supardia—the former leader of the Superd's Warrior group—to form Dead End, a successful adventurer party. Making a name for themselves, the trio journeys across the continent to make their way back home to Fittoa. Following the advice he received from the faceless god Hitogami, Rudeus saves Kishirika Kishirisu, the Great Emperor of the Demon World, who rewards him by granting him a strange power. Now, as Rudeus masters the powerful ability that offers a number of new opportunities, it might prove to be more than what he bargained for when unexpected dangers threaten to hinder their travels.

After his relationship with Eris Boreas Greyrat reaches new heights, Rudeus Greyrat is ecstatic. Unfortunately, his joy is short-lived, as Eris suddenly abandons him to embark on her own journey. Believing that Eris has lost all interest in him, a heartbroken and depressed Rudeus sets forth to the Northern Territories. With his sole goal being to locate his mother on the vast continent, Rudeus wonders if persisting through daily life is worth the pain, falling into a robotic routine as he endlessly ruminates on his lost love. However, the dangers of the North soon prove that one cannot survive with a dulled mind. While on a quest with the party Counter Arrow, with whom he recently became acquainted, Rudeus has a brush with death—an experience that forces him to finally snap out of his despair. With his newfound teammates, Rudeus rediscovers the pleasure of daily adventuring and moves forward with his original goal of living his second lease on life to the fullest.

Since childhood, Hana Haruyama has been enthralled by the art of storytelling. After watching a child her age perform on television with mesmerizing grace, Hana decides to try it herself. She practices by reciting tales to Tonaki Island's children, who are always enthusiastic about her performances. However, growing up in such a small community, Hana remains unaware of the possibilities beyond her world, satisfied with how things are. Entering Sumomogaoka High School as a first-year student, Hana catches the attention of Mizuki Usurai, the president of the broadcasting club, with her skills. Despite Hana's hesitation and anxiety about the road ahead, Mizuki successfully convinces her to join the club, nurture her gift, and perhaps one day reach the top—the nationals of the NHK Broadcasting Competition.
