Daki no Obi no Oni

The obi displays a cruel, obedient, and confident personality reflecting Daki's own temperament. It considers humans prey and shows no concern for the people imprisoned within its fabric.

It obeys Daki's instructions and operates independently while separated from her body. Its ability to converse and make immediate decisions gives it the appearance of an individual subordinate even though it remains part of Daki's Blood Demon Art.

The obi becomes increasingly aggressive when Demon Slayers interfere with its underground storehouse.

The obi is composed of living demonic fabric and can alter its shape, length, and direction. Its edges can slash through targets, while its flexibility lets it attack from multiple angles or travel through spaces unsuitable for a human-shaped body.

It can absorb humans into its fabric and preserve them as two-dimensional-looking figures within the sash. Daki uses this ability to store people she intends to consume later.

Because the obi is part of Daki, destroying or damaging it does not operate like killing an independent demon. Its strength also increases when its power is returned to Daki's main body.

The obi operates beneath Yoshiwara while Daki maintains her human disguise as an oiran. It stores numerous abducted people in an underground chamber, allowing Daki to conceal her victims.

Inosuke Hashibira discovers the underground chamber while investigating disappearances in the Entertainment District. He attacks the sash and begins freeing its prisoners.

Makio, Suma, and Zenitsu Agatsuma are among the captives held by Daki's obi. The confrontation helps expose the scale of Daki's activity beneath Yoshiwara.

Daki creates and controls the obi through her Blood Demon Art. The sash functions as an extension of her body and carries out tasks while separated from her.

Inosuke Hashibira discovers the obi's underground storehouse and fights it while freeing its captives.

Makio and Suma are captured while investigating the Entertainment District.

Zenitsu Agatsuma is among the people stored within the obi after disappearing during the mission.
