In a desperate and courageous move, Ubuyashiki uses himself as bait to lure Muzan into a trap, setting the stage for an epic confrontation.

Tamayo and Himejima join the battle against Muzan, adding to the stakes.

Muzan and Ubuyashiki’s Revealed Connection

The finale begins where the previous episode left off, with Muzan Kibutsuji infiltrating the Ubuyashiki mansion and coming face-to-face with Kagaya Ubuyashiki for the first time.

Muzan declares his intent to end Ubuyashiki’s dream of defeating him, to which Ubuyashiki reveals their shared bloodline. Indifferent, Muzan questions the implication of this revelation.

Ubuyashiki explains that their family, having birthed a monster like Muzan, was cursed, leading to frail children who die young.

In a bid to break this curse, they dedicated themselves to defeating Muzan, marrying into priest families to slightly alleviate the curse, but no family member has lived beyond 30 years.

Muzan mocks this story, doubting its truth, given his unpunished reign of terror for over 1,000 years. Ubuyashiki counters, asking Muzan about his dream.
