Tengen Uzui was born of shinobi. There were nine children in the family. All of them were harshly trained for them to be better shinobi. They were taught the importance of the clan and of killing innocent lives to save the clan. Three of his brothers died before they were 10 because of how intense the training are.

With the remaining six siblings, his father had him fight his siblings. They were not aware of the identity of the people they were killing as their faces were covered with masks. Tenzen, upon killing two of his brothers had discovered the trick.

When he was 15, he was married to three women. His clan practices polygamy and the sole reason for marriage is for them to bear more children. At the same age, 7 of his brothers were dead. Only he and his youngest brother were alive. The youngest brother had adopted the mindset of their father.

Tenzen left their village with his wives and started a new life. Tenzen would later teach his wives to value their lives above the mission. He anguished whether he should kill every member of the clan or not. Later he realize he could not kill his brother and father.

After leaving his village, Tenzen searched for Kagaya Ubuyashiki so he could join the Demon Slayer Corps. When he rose to the ranks of Hashira, Sanemi and Kanao are not Hashira yet. When he met Tanjiro and Nezuko, he expresses with disgust that Tanjiro was traveling with a demon.

While he got intrigued by the reason Tanjiro is traveling with Nezuko, he strongly disagrees that they should travel together. Tengen was the one who was given the assignment of infiltrating the Red Light District.

He is not supposed to be working with Tanjiro, Inosuke, and Zenitsu but when Tanjiro opposed using the unwilling demon slayers to infiltrate the District and volunteered himself, Tengen got no choice but to do his bidding. Tengen sent his three wives to infiltrate the district. The boys also went and gather information in the district while Tengen would lie low.

Tengen sensed that there is a danger when Zenitsu, who pretends to be a girl and worked at the Kyogoku House went missing. He investigated the disappearance himself and after pressing the manager, he got information that a certain Warabihime is the one causing the disappearances.

Tengen was able to save both Zenitsu and his wife Hinatsuru. When he fought Daki, he was able to immediately decapitate her and was even surprised that she is an Upper Moon.

Tengen was surprised by the presence of another demon Gyutaro. He poisoned Tengen and avoided getting decapitated. After Tengen was able to defeat the demon siblings, he lost his left arm and eye. The poison of Gyutaro started spreading inside the body of Tengen.

Nezuko used her Blood Demon Art to burn the poison out of his system and he was able to rejoice with his wives. Tengen informed Obanai that he is retiring as a demon slayer. Despite being a retired member of the Demon Slayer Corps, Tengen helped in the Hashira training.

He and his wives trained the members in the first level which is the basic stamina training. During the Infinity Castle Arc, Tengen alongside Shinjuro Renguko is on another side of the Ubuyashiki Estate when it was taken into the Infinity Castle. They stand guard outside the room of the surviving Ubuyashiki as they map out the castle to provide instruction to the demon slayers.

Physical Appearance

Tengen is a very tall man. He has a wide frame and is bulky. His white hair has uneven lengths the longest reaches his shoulders. His thin maroon eyes seem to slant upwards. He is a good-looking man and he uses his looks in missions where he would need persuasion.

As a demon slayer, he wears a turquoise sleeveless demon slayer uniform. He wraps a burgundy cloth around his calves, his tattsuke hakama pants tucked in and white strapped zori sandals.

He wears golden rings around each of his arms and another for each of his wrists. The golden rings on his wrist appear to be holding a pair of fingerless gloves secured in his middle finger. Tengen also wears a white head wrap.

Two chains of the gemstone can be seen hanging from the white headband he is wearing. He wears red eye makeup around his left eye. The make-up consists of dots of different sizes that run inwards towards his eyes.


Tengen wants everything and everyone around him to be flashy. His eccentricity and flamboyant character can make him demanding of others. He treats the demon slayers harshly and insults them for not completing his training.

He hates the idea of being plain. He would always declare that he is the god of flashiness. He deeply cares for the people he loves, his three wives. He looks up to people like Kyojuro Renguko and his fellow Hashira.


Tengen is the second strongest Hashira in the current generation. His background as a shinobi makes him a skilled combatant who has immense stamina, reflexes, and strength. He is an expert in stealth as he learned this when he was a shinobi. He is capable of fighting two Upper Moon at the same time.

Although he was heavily injured and almost died, Tengen was able to match their skills. His tactical skills and sharp sense are a few of the skills he learned as a shinobi that were proven useful when he became a demon slayer. Using echolocation he can easily detect underground battles. He also converts the enemy’s attacks into the musical score so he can easily read it.

Tengen uses dual-wielding Nichirin cleavers that he can wield using only one hand. Being one of the most powerful swordsmen in the entire generation, he was able to easily adapt to Gyutaro’s mantis-style fighting. He also uses anti-demon bombs. He invented Sound Breathing. There are three known forms and he masters it all.
