Third season of .

Kazuma Satou, former NEET and current reincarnated adventurer, finally returns home after the incident at the Crimson Demon village. He is joined by his ever-reliable companions: self-absorbed goddess Aqua, one-trick pony arch-wizard Megumin, and masochistic crusader Lalatina Ford "Darkness" Dustiness. Following their recent exploits, the party is one step closer to vanquishing the Demon King and his armies—a terrifying task that Kazuma is eager to ignore for as long as possible. Things, however, are not going as smoothly as the group would like; they are constantly racking up debt, getting sidetracked during missions, and falling into traps due to their recklessness and eccentricities. As the party struggles with their perennial issues, they receive an invitation from a princess interested in hearing tales of the group's "heroic" deeds. Darkness' pleas to refuse the invitation only fire the others up to accept it, marking the start of yet another uncanny adventure with unforeseen consequences.

Adaptation of the Hashira Training Arc. The Hashira, the Demon Slayer Corps' highest ranking swordsmen and members. The Hashira Training has begun in order to face the forthcoming battle against Muzan Kibutsuji. Each with their own thoughts and hopes held in their hearts, a new story for Tanjiro and the Hashira begins.

Trying to move on in his life, former professional golfer Kazuyoshi Igarashi arrives at Hinoshima Island for a job at its development center. Expecting the island to be a very rural area with nothing much to offer, Kazuyoshi cannot hide his amazement when he discovers a complete golf course made by the island's inhabitants. Using the seaside terrain to their advantage, the people there have adopted golfing as their hobby. To add to his surprise, Kazuyoshi meets a young girl named Tonbo Ooi, who has been playing golf using only a 3-iron—a notoriously difficult-to-use club. As the former pro gets more involved with Tonbo and witnesses her seemingly impossible shots, he begins to see golf in a whole new light, rediscovering how fun the sport can actually be.
