Gyutaro
Along with Daki, Gyutaro also held the title of Upper Rank 6 within the Twelve Kizuki. His Blood Demon Art might seem simple, but it's pretty effective when used properly — something that Gyotaro showcases during his fight with the Sound Hashira and Tanjiro.
However, given that he and Daki held the position of the lowest Upper-Rank demon, there was always a fighting chance against these foes. A combination of Tanjiro's developing aptitude with the Hinokami Kagura and Tengen's experience as a Hashira ultimately spelled his demise.
