Yuu☆Yuu☆Hakusho EP29 - Flowers of Blood

Both Kuwabara and Rinku display the ability to control their spirit energies using their spirit sword and yo-yos, respectively. They both are pushed outside of the ring, yet Rinku manages to defeat Kuwabara. Kurama battles Roto, one who can morph his finger into a sickle, who threatens to have his brother kill Kurama's human mother. However, Kurama deceives Roto by conversing with him until a seed Kurama planted in Roto at the start of the round blooms, killing Roto from the inside.
