Daki

Character Description: Daki

1. Backstory

Daki is one of the Upper Moon demons in Demon Slayer: Kimetsu no Yaiba, holding the rank of Upper Moon Six alongside her brother, Gyutaro.

Before becoming a demon, she was a human named Ume, a young girl who lived in the red-light district of Yoshiwara during the Edo period.

As a human, Ume was known for her extraordinary beauty. However, her life was harsh—she grew up in poverty with her sickly brother, who was looked down upon by society. Due to her beauty, she became an oiran (high-class courtesan), but she was also cruel and arrogant from a young age.

One day, she stabbed a samurai in the eye after he insulted her, and in retaliation, she was burned alive. As she lay dying, Gyutaro found her and was on the verge of despair until an Upper Moon demon (Doma) offered them the chance to become demons. From that moment, they shared a body and became ruthless hunters of humans, enjoying their eternal life in the darkness.
