Tengen Uzui is a major supporting character of Demon Slayer: Kimetsu no Yaiba and a major character in the Entertainment District Arc. He was a former member of the Demon Slayer Corps, standing as the previous Sound Hashira.

Fighting Style

As a Hashira of the Demon Slayer Corps, Tengen is one of the most powerful and skilled swordsman in the entire organization. Unlike most Demon Slayers, Tengen chooses to utilize a dual-wielding swordsmanship style with his Nichirin Cleavers, making use of a nunchucks-esque sword wielding style. Tengen displays his unique and extraordinary swordsmanship skills during his battle against Gyutaro, managing to adapt to the Upper Rank's "mantis-like" fighting style and go toe-to-toe with him for an extended period of time despite the Upper Rank having over a century of combat experience. Tengen can also use his sword wielding expertise in conjunction with his anti-demon bombs with great synergy, making him all the more dangerous. He also showed the ability to wield his Nichirin Cleavers with only one arm. In addition to traditional slashes and swings, Tengen has also been shown to spin his blades by their chain; the whirling motion allowing him to block blows and quickly attack in retaliation, with the blades in constant rapid motion.

Breathing Style

Sound Breathing: A Breathing Style that Tengen created himself. Sound Breathing seemingly combines Tengen's heightened sense of hearing, his Musical Score technique, his shinobi expertise as well as his dual Nichirin cleavers and his anti-demon bombs.

Techniques

• First Form: Roar - The user lifts their twin swords above their head and slams them down with great force whilst simultaneously creating an explosion with his bombs to deal massive physical damage, causing a loud sound resembling thunder as a result.
• Fourth Form: Constant Resounding Slashes - The user holds their swords apart and spins them rapidly in conjunction with releasing his bombs, creating massive explosions while defending themselves from attacks.
• Fifth Form: String Performance - The user holds one of their swords with a reverse grip and spins the other using the chain that connects them. They couple this by also releasing numerous bombs to detonate, causing great explosions that deal massive physical damage.

Dual Nichirin Cleavers: Befitting Tengen's flamboyant personality, he carries an equally flamboyant set of weaponry. As his main weapons, he uses two gigantic Nichirin cleavers that are amber in color, which each have a notch in the sharp ends of their blades and are held together at the hilt by a metal chain, making it very reminiscent to nunchucks. His swords are said to have large amounts of explosive power, and it is stated that, until Tengen's fight with Upper Rank 6, no one had ever survived a blow from them. His hilt is circular shaped with 4 slight indentations and gold in color, there's a maroon ring that connects to the center; it has an outer green border. His blades are engraved with the phrase Destroyer of Demons. Due to his sword's huge size, Tengen doesn't use a sword sheath and instead carries them on his back, having them wrapped in cloth.

Explosive Beads: Tengen carries dozens of black beads that create large explosions with the slightest impact that are capable of harming the bodies of Upper Rank demons.

Standard Kunai: Like his three wives, Tengen carries around dozens of standard black kunai, which he used to threaten Omitsu's husband to reveal information about Zenko's and Hinatsuru's disappearance and to destroy the Obi sash that captured Hinatsuru.
