engen Uzui is the Sound Hashira (one of the nine highest-ranking Demon Slayers) in Demon Slayer: Kimetsu no Yaiba.
He's a tall, extremely muscular, flamboyant, and very confident shinobi-style swordsman known for his distinctive appearance:
Personality-wise, Tengen is loud, bombastic, and constantly emphasizes being "flamboyant" (he uses the word obsessively). He views flashiness and style as extremely important and looks down on anything he considers plain or boring. Despite his eccentric and somewhat arrogant demeanor, he's highly capable, loyal to his fellow Hashira, and deeply protective of the three beautiful kunoichi wives he travels and fights with (Makio, Suma, and Hinatsuru).
His fighting style revolves around Sound Breathing, which incorporates his enhanced hearing, explosive sound-based attacks, and dual Nichirin cleavers connected by chains, allowing him to create devastating shockwaves and aerial maneuvers.
He's one of the most memorable and over-the-top characters in the series, especially during the Entertainment District Arc where he plays a central role.
