Zenitsu and Inosuke didn’t join Tanjiro on his journey to the Swordsmith Village in Season 3 of Demon Slayer, which left fans upset without their usual antics. The season focused more on other characters like the Mist and Love Hashira, providing a balanced narrative without overcrowding.
As Season 4 of Demon Slayer kicks off with the Hashira Training Arc, viewers will notice the absence of another crucial character. Episode 1 introduces several light-hearted moments, including Nezuko’s newfound ability to speak and Zenitsu’s comical reaction.
However, the episode also hints at an impending threat—Muzan’s anticipated retaliation against Nezuko’s recent achievements.
Nezuko’s absence from the Swordsmith Village arc is briefly addressed in the manga, where Tanjiro reflects on leaving her behind for her safety and recovery. Nezuko’s need to recuperate is due to her unique diet and previous expenditure of energy, making it challenging for her to regain her strength as quickly as other demons.
The decision to keep Nezuko out of the current narrative allows for the development of other characters, especially the Hashiras, whose backgrounds and ambitions need to be dealt with.
While Nezuko’s complete absence from the anime isn’t confirmed, her role in the arc is minimized to accommodate the broader storyline and character growth.
