~Tengen Uzui~ 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.
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.
