Tengen Uzui, the flamboyant Sound Hashira in Demon Slayer: Kimetsu no Yaiba, is a towering, muscular swordsman with silver hair, flashy accessories, and a personality to match. A former shinobi, he fights demons using the Breath of Sound style, dual Nichirin cleavers linked by a chain, and explosive techniques, all while analyzing enemy movements through sound. Though eccentric and obsessed with “flashiness,” Tengen is deeply loyal and protective, especially toward his three wives—Makio, Suma, and Hinatsuru—showing a caring side beneath his bold, extravagant exterior.
