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.
