Tengen Uzui

Tengen's flamboyant demeanour. Tengen is an eccentric and flashy individual, always wanting to be "flamboyant", possessing a need for everything to be flashy and outstanding, even proclaiming that he is the god of flashiness and festivals. This is shown when he gets excited imagining how "flamboyant" it would be if Tanjiro Kamado's blood vessels exploded, and tries to forcefully haul Aoi Kanzaki off to the Entertainment District with him so she can unwillingly help him with a dangerous mission, even spanking her. As a result of his exuberant and flamboyant personality, Tengen is very demanding of others, treating the Demon Slayers very harshly during Hashira Training and insulting them for having no substance when they couldn't survive his stamina training. Furthermore, he also abhors the idea of unflashy things, as shown when the Hashira openly expresses his hate for plainness. Tengen proclaiming that he is a god. He is usually seen talking boastfully, proclaiming that he is "god" in front of Tanjiro, Zenitsu and Inosuke, even calling them trash and declaring that if he tells them to become dogs, they must become dogs, and if he tells them to become monkeys, they must become monkeys. Tengen even demands for the trio to always humor and stoop down to him, imploring him for favours and always doing their best to flatter him. This was also shown in his initial encounter with Upper Rank Six, Gyutaro, proclaiming that he was in tip-top shape despite being severely poisoned. However, Tengen does possess an extremely caring side that is masked under his flamboyant façade, one he only shows to those that are extremely close to him, most notably his three wives, Makio, Suma, and Hinatsuru, who Tengen is shown to truly love and care for, praising and encouraging Makio and Suma after their undercover mission and assuring Hinatsuru that she has completed her mission and telling her to get out of harm's way. Furthermore, Tengen also declares that they must value their lives above all others as they are precious to him. This is especially shown when Gyutaro gags Hinatsuru with his hand, Tengen panics and furiously yells at the demon to leave his wife alone. After the events in Yoshiwara, Tengen also becomes more friendly towards Tanjiro, Zenitsu, and Inosuke. "Do I look like I have talent to you?" Although he can be very boastful and expressive, Tengen also shows a side of modesty and humility. He openly denied Gyutaro's statement that he was blessed with any talent, comparing himself to the other Hashira and especially Kyojuro Rengoku. This implicates a sort of inferiority complex, further proven by the fact that he told himself that he could never become someone as great as Kyojuro. Tengen is also shown to harbor regret over the fact that he has let so many lives slip through his fingers over the years. Kagaya Ubuyashiki praised Tengen for the hard path he chose and for facing forward and fought to protect human lives despite carrying all of his conflicts and contradictions he hides behind his loud and confident façade, which caused Tengen to deeply respect Kagaya from that moment on. Tengen has exceptional compassion with strong morality, which Kagaya acknowledged. Despite being a shinobi that has traditionally valued completing the mission over all else, Tengen has rejected that ideology after seeing its brutal effect on his family, despising his father for forcing him and his siblings to endure through brutal training and even pitting them against each other in a final lethal test. He believes that his subordinates, whether they be his wives or the Demon Slayers under his command, should value their lives and the lives of innocents over their missions or his own. Tengen especially hated the idea of becoming like his brother or father, who were apathetic towards human lives, wanting to desperately abandon what he was taught by them; even then, he choose to simply cut his ties instead of killing them due to his morality. He also chose to be a Demon Slayer to protect innocent people from being harmed by demons. Following his retirement, Tengen was brought in by the active Hashira to assess fitness and stamina during Hashira Training. Tengen would prove to be a strict teacher, frequently yelling and berating the trainees for their weaknesses and exhaustion, whilst also amusing himself by intimidating them. Despite this, he does genuinely care for his pupils, as Makio mentioned that he did not eat until the last trainee returned, even going so far as to search the mountain to find them should they get lost. Tengen himself claimed that because Kagaya entrusted the trainees in his care, he wasn't going to let them burn out. In addition, according to his wives, Tengen still has a desire to fight and that he calls out in his sleep, blaming himself for relinquishing his position in the Corps. Despite this, Tengen remained retired and dutifully served as a bodyguard ...

Tengen is a very tall, broad-shouldered, and incredibly muscular man with lightly-tanned skin and white hair. His hair is of an uneven length, the longest strands reaching his shoulders, and is styled with three more notable, shorter clumps arching up to fall as bangs between his eyes and on either side of his face. He has thin, dark fuchsia eyes that appear to slant inwards, each with one long eyelash flowing to the far side of his face. He also painted his fingernails and toenails with claret and bright green color. He is considered very attractive as noted by many women and even by Zenitsu; this has led him to use his looks as a tool for his missions whenever persuasion is necessary. During his service as the Sound Hashira of the Demon Slayer Corps, Tengen wore a highly customized, sleeveless version of the standard Demon Slayer uniform. His uniform was black in the manga and tinted a deep dark turquoise in the anime. It consisted of a sleeveless button-up jacket with a stand-up collar, gold buttons, and a shirt pocket on the left breast, with the kanji for |Metsu}} engraved on the back of the uniform. Underneath, he wore a white sleeveless collared undershirt. The uniform was secured with a white belt at the waist and included matching tattsuke-hakama pants tucked into burgundy cloth wrappings around his calves. On his feet, he wore white zōri sandals with white straps and dark turquoise [https://en.m.wikipedia.org/wiki/Tabi tabi socks] to match his uniform. Tengen is accessorized flamboyantly, wearing two thick, golden rings around his upper arms and a pair of fingerless purple gloves. These gloves were secured with two silver bands around the middle fingers and fastened at the wrists with two thinner golden rings on each side. As well as this, Tengen sports a white head-wrap that covers his hair, leaving only a thin ponytail visible to fall behind his head from between its layers. Adorning his forehead was a striking pale gray headband, embellished with six pale pink gemstones—three large ones arranged in a horizontal row across the center, and three smaller ones arranged in a triangular formation on the far left side. From each side of this headdress hung chains of smaller pale blue gemstones, which framed his face like earrings or decorative tassels. Additionally, Tengen wore distinctive red eye makeup on his left eye, composed of alternating large and small dots that extended inward toward the corner of his eye. He also wears a pair of two golden cuff earrings on each ears. After his retirement from the Demon Slayer Corps due to the injuries he has sustained during his fight with Gyutaro, Tengen changes his appearance to coordinate the loss of his left eye and hand. He now wears a long, burgundy colored yukata with white yuban collar along a light purple obi tied around the waist, and an indigo blue haori. He also replaces his old head-wrap with a dark eyepatch adorned with what look to be the remaining gemstones left over from his old headdress, leaving his hair to fall loosely past his shoulders. In addition, a long scar from where Gyutaro's kama sliced his left eye is visible under his eyepatch. He also wears a pair of zōri.

Overall Abilities
Tengen fighting on equal grounds with Gyutaro, despite being poisoned and losing a hand. As a Hashira of the Demon Slayer Corps, Tengen is a very powerful and skilled combatant. He has displayed incredible physical feats of strength and speed, being seen as the second physically strongest, and the fastest runner out of the Taisho era's Hashira. He could match the combat proficiency of both Daki and Gyutaro, both Upper Rank demons that have fought and killed numerous Hashira in the past , as well as having over a century of combat experience. Tengen was also able to effortlessly decapitate Daki without her even perceiving his movements, which caused him to believe she was no Upper Rank demon at all. Impressively, he was able to fend off the combined efforts of Daki and Gyutaro while being infected by a poison that would kill someone quickly under normal circumstances, even managing to protect bystanders in the process. Tengen has also showcased great skill and precision in using explosives, minimizing damage dealt to the surroundings and maximizing the damage dealt to his opponents. Due to his shinobi training, Tengen has greater tactical skills and sharper senses than the average person, most notably his sense of hearing, which helped him greatly during the course of the battle with Upper Six. Even after losing his left hand to Gyutaro, Tengen was able to fight the Upper Rank on even terms due to completing his Musical Score, allowing him to accurately predict and deflect Gyutaro's attacks, cut off his arm and pin him down at the cost of losing his left eye. Nonetheless, due to the poison circulating in his body, he was unable to attempt a finishing blow and needed Tanjiro to do so. Indomitable Will: Tengen possesses an undaunted spirit and immense willpower, never faltering even when faced with disadvantages and difficult circumstances. Despite being poisoned in the beginning by Gyutaro, he boldly proclaimed he could fight just fine, even attacking both Daki and Gyutaro at the same time. He appeared to be ecstatic while deflecting multiple poison blood blades even with a missing hand and numerous cuts in his skin. Even when his left eye gets slashed out, he pushed through all the damage until the demons were defeated. Shinobi Training: Before joining the Demon Slayer Corps and becoming a Hashira, Tengen descended from a family of shinobi. Tengen received extremely harsh training that killed all of his siblings except for his younger brother, who became cold and heartless. However, as a result of his intensive shinobi training, Tengen possesses great technical skill in weaponry such as kunai and explosives. His training also made him extremely pain tolerant and poison resistant, which saved him from Gyutaro's poison and allowed him to fight despite suffering numerous injuries and losing his hand. *Enhanced Stealth: Tengen is extremely stealthy, moving so silently that he doesn't make a single sound nor disturb the air. His stealth allowed him to evade the senses of both Tanjiro and Inosuke, both of which possessesing a heightened sense of smell and touch respectively. Later, Tengen was able to sneak up on and decapitate Daki, an Upper Rank demon, without her noticing. *Poison Resistance: As a former shinobi, Tengen has been shown to possess high resistance to poison to the point where he could continue fighting while under the effects of a poison from Gyutaro that would have killed someone instantly under normal circumstances. Tactical Intellect: Due to accumulating close to two decades of experience as both a shinobi and Demon Slayer, Tengen has incredible judgement, making decisions on the fly while in battle with Upper Rank demons to protect bystanders and minimize the damage dealt to the surroundings. Even when he was held back by Gyutaro's poison, Tengen was able to properly determine the most efficient strategy to fight off the Upper Rank demons and even fooled Gyutaro into thinking he was dead by stopping his own heart to prevent himself from dying from his poison, which managed to give Tengen an edge against him as he then completed his Muscal Score Technique.
