Appearance
Tengen Uzui is a tall muscular young man with white hair though he is usually seen wearing a headwrap featuring a plate covered with jewels of various sizes. He wears a sleeveless version of the standard demon hunter uniform. After his retirement due to injuries sustained during his fight with Gyuutaro(He lost an eye and an arm), he is seen during the Pillar Training Arc wearing a patterned yukata with a black haori while replacing his headwrap with a black eyepatch featuring jewels of various size. He held his swords on his back prior to his retirement.

Natagumo Mountain Arc
Tengen was present with his fellow Pillars when Kamado Tanjirou awoke.

Functional Recovery Training Arc
Kochou Shinobu noted that Tanjirou was on trial, but Tengen simply stated that he would cut Kamado Nezuko's head off "flamboyantly", agreeing with and repeating this latter word when Himejima Gyoumei suggests they kill her. When Tanjirou reiterated his belief that Nezuko will not harm any humans, the Sound Pillar told him not to give them lip service, but rather a more complete explanation. He then remained silent when Kanroji Mitsuri asked if they should be dealing with their subordinate's trial without Oyakata-sama's input. After Tanjirou headbutted Shinazugawa Sanemi, Tengen looked at Mitsuri when she laughed with a neutral expression.

Swordsmanship
Breath of Sound (の): A Breath unique only to Uzui. The Sound Breath is branched out from the Lighting Breath. The Breath's developed a battle strategy a Score, which involves Uzui reading his opponents movements and deconstructing them into sound, by analysing the rhythm of their movements like this he is able to take advantage of their openings to much greater effect, being able to strike at their openings similar to making the beat to a song. In conjunction with this he uses small but powerful anti-demon bombs, made with a special gunpowder, which proved capable of overpowering an Upper Moon Demon briefly.
 * 1) First Style: Thunder (ノ) - Uzui lifts his twin swords above his head and slams them down with great force creating an explosion with his bombs, causing a loud sound resembling thunder.
 * 2) Fourth Style: Death Knells of Avīci - Uzui holds his swords apart and spins them rapidly in conjunction with releasing his bombs, making this technique a combination of offense and defense.
 * 3) Fifth Style: Symphony of Shrill Strings - Uzui holds one of his swords with a reverse grip, and spins the other using the chain that connects them. He couples this by also releasing numerous bombs to detonate. This technique was able to overpower an Upper Moon demon.
