Yuda (also romanized as "Juda") is the successor of Nanto Kōkaku Ken (South Dipper Crimson Crane Fist) style and one of the Nanto Rokusei Ken, bearing the destiny of the "Star of Enchantment or Beauty" which is also referred to as the "Star of Betrayal".

Known as the infamous traitor of the Nanto Rokusei Ken, Yuda betrayed them in order to ally himself with Raoh, along with 27 subordinate branches of Nanto Sei Ken. It was later revealed that Yuda was manipulated by Souther into doing so, and consequently plunged the Nanto Rokusei Ken into chaos. In his vain and treacherous nature, Yuda keeps a harem of concubines who are forced to worship his beauty, and he is more than willing to sacrifice his underlings for his own gain.

In the past, Yuda kidnapped Mamiya on her 20th birthday, murdering her parents before her eyes and making her part of his harem, until she eventually escaped. When Rei discovered this, he challenged Yuda to avenge Mamiya's honor. Yuda was hiding a deep envy of Rei prior to the apocalypse, feeling that Rei's beautiful Nanto Suicho Ken had surpassed his Kokaku Ken style. After Yuda is defeated by Rei, he embraces the feelings of respect and admiration towards his enemy and kills himself with Rei's hands. In death, he concedes that Rei was the more beautiful fighter.
