Ushiromiya Kinzo

Season 1
Kinzo Ushiromiya, Grandfather of Battler Ushiromiya, appeared in the finale of TFR Season 1, having enough of his grandson's jobbing, came in and gave him an ultimatum.

Either win against him in a match and become the Lord of Rokkenjima, proving to Kinzo that he has to power to keep wrestling, or lose and to go back to The Golden Land.

With this against him, Battler realized the, that Kinzo Ushiromiya was already dead, and proceeded to beat the seven shades of shit out of his grandfather, earning the love of the audience and the title of Golden Sorcerer.

Season 2
On Season 2, he somehow appeared in the King of Jobbers Title Championship. It is unknown if this is the real Kinzo, it may be in fact, Battler disguised as Kinzo in order to keep the illusion alive or some scheme to prove witches aren't real.
