Tengen and Gyutaro

Uzui Tengen is a Slayer and the Sound Pillar of the Demon Slayer organization. He grew up in a shinobi clan but left due to his father's harsh philosophy. An eccentric, flamboyant, and loud man, he calls himself the "God of Brightness and Festivals." Behind his tough demeanor, he conceals a deep concern for his loved ones and ordinary people. Tengen has three kunoichi wives—Hinatsuru, Makio, and Suma—whom he traveled to the Red Light District to rescue. He uses the unique Breath of Sound, a branch of the Breath of Thunder. He wields two enormous twin Nichirin swords with black and orange blades, connected by a strong chain. He also makes extensive use of special explosive pellets in combat. He has phenomenal hearing, allowing him to use the "Musical Score" technique to predict enemy movements. He always wears bright red makeup on his left eye.

The Red Light District was beautiful: both the atmosphere and the townspeople. Tengen Uzui and his students—Tanjiro, Inosuke, and Zenitsu—went on a mission. It ended up being a bit surreal, but let's leave that aside... It turned out the Red Light District was home to a demon from the Upper Moon Six named Daki.

Tengen easily cut off her head, but another demon emerged—Gyutaro. To kill them, both their heads would have to be cut off. Gyutaro attacked Tengen, not even giving him a chance to catch his breath. Tengen was sent flying into the wall by the blow, barely able to raise himself up on his elbows.

"H-hah... Not a bad hit! Brilliant! But mine will be even more brilliant!"
