Should Have Been

The twenty-ninth episode follows the slayers through the dreams Enmu has woven for them. The demon's young accomplices use ropes formed from his Blood Demon Art to enter those dreams and hunt the cores that anchor each victim's life. The focus stays on Tanjiro, who slowly realizes his happy reunion is an illusion and steels himself to leave it behind in order to keep fighting.

Dreams of comfort

Zenitsu imagines Nezuko as his sweetheart, Inosuke leads a cave expedition with his comrades as followers, and Kyojuro relives a cold exchange with his disapproving father before resolving to keep making his brother Senjuro proud. The children sent into the dreams try to reach the spiritual cores hidden beyond each dream's edge. The girl who enters Kyojuro's mind is seized by the throat even as he sleeps, his instincts crippling her where she stands.

Letting go

Strange slips of the tongue tip Tanjiro off that something is wrong, and a warning from his own reflection drags him toward the truth. On the train, Nezuko spills from her box, headbutts her brother, and triggers her Blood Demon Art, its flames helping rouse him. Tanjiro tells his dream family that he wishes none of it had happened, then walks away from them, accepting that they are gone. With his father's spirit urging him to take up his blade, he understands what he must do and drives the sword toward his own neck to break free.

The eyecatchers recreate two chapter covers from the source. Several small moments are anime-only, such as Tanjiro carrying logs and murmuring to Nezuko. The discovery of Nezuko's box also differs: the manga places it in his backyard, while the anime sets it by the river where he goes for water, and the family confrontation shifts from a forest to a snowy field.
