KEY REVELATIONS

Nezuko, turned into a demon, fights her own hunger to shield Tanjiro. Whatever Muzan's blood did to her, part of her held.

Sabito and Makomo, the masked children who trained Tanjiro all winter, are the spirits of Urokodaki's students, all killed at Final Selection.

Tanjiro's Nichirin blade turns black, a color so rare that nobody can say what it means for its bearer.

Muzan Kibutsuji, the first demon and the one who slaughtered the Kamado family, hides in plain sight in Asakusa as a husband and father.

A scratch of Muzan's blood is enough to turn a passing stranger into a demon on the spot.

Tamayo defied Muzan and lived. She asks for Nezuko's blood to research a cure for demonhood.

Saying Muzan's name is death: the curse woven into demon blood destroys Susamaru from the inside.

Kyogai was excommunicated from the Twelve Kizuki when his Blood Demon Art stopped evolving. Demons are discarded the moment they stop being useful to Muzan.

The Hinokami Kagura dance the Kamado family performed every New Year doubles as a breathing style older than any taught in the Corps.

Giyu blocks Shinobu's blade to protect Nezuko, breaking Corps rules on the strength of what he saw two years earlier.

Urokodaki's letter stakes three lives on Nezuko: if she ever eats a human, he, Giyu, and Tanjiro will answer for it with their own.

Stabbed three times by Sanemi and starved for two years, Nezuko turns her face away from human blood in front of the assembled Hashira.

Muzan dissolves the Lower Ranks in a single night. Enmu alone leaves the Infinity Castle, carrying fresh blood and orders to kill a Hashira.

Enmu has fused himself with the entire Mugen Train. All two hundred passengers are hostages, and the train itself is the demon.

The oiran Warabihime who has ruled the Kyogoku House for years is Upper Rank Six of the Twelve Kizuki.

Daki does not die when beheaded because Upper Six is two demons: her brother Gyutaro shares the rank and the body.

Gyutaro's death is the first Upper Rank defeat in a hundred years, and it drags the remaining Upper Ranks in front of Muzan for the first time in a century.

The Yoriichi Type Zero doll needs six arms to imitate the swordsman it was modeled on three hundred years ago.

A sword from over three hundred years ago sleeps inside the broken doll, rusted but forged by a master.

Muichiro's lost memories return: his twin brother Yuichiro, the attack that killed him, and the reason 'Mu' means infinity.

Nezuko stands in the morning sun and does not burn. She is the first demon to conquer the sun, and her words begin to return.

Muzan's target changes: if he devours Nezuko, the sun stops being his cage. The Corps answers with joint Hashira Training.

Giyu never passed Final Selection. Sabito saved him and died doing it, and Giyu has never believed he deserved the Water Hashira title.

Gyomei's past surfaces: the temple children he sheltered, the demon that killed them, and the murder charge pinned on the man who fought it bare-handed.

Kagaya and Muzan come from the same bloodline. The Ubuyashiki family's curse and the Corps' thousand-year hunt share one origin.

Kagaya trades the Ubuyashiki Mansion and his own life for the opening blow, and Tamayo's Blood Demon Art pins Muzan long enough for the Hashira to converge.
