- The twin successors of the Nishin Fūraiken (二神風雷拳, "Dual Gods Wind Thunder Fist") style. They are guardians for the Cassandra gate, but are only reluctantly working for Uighur because he was holding their younger brother Mitsu as a hostage and regret killing numerous times. Kenshiro spared their lives since Kenshiro noticed that their eyes are "full of sadness". In the TV series, they are labeled traitors for not killing Kenshiro, as a result his brother is executed in front of them. They help Ken and the others into the Cassandra prison. But are killed by Qasim and Zarqa of the Ken-oh Royal Guard in the manga (Bulg in the TV series).
