Traitor is the thirty-second chapter of the manga Kengan Omega.
With Tommy Strummer attaining victory against Mark Myers, Yumigahama and Jose have a spat, culminating in Yumigahama sucker punching Koga, much to Jose (and Ryuki's) ire. However Toyoda quells the situation.
Some days later, Koga tells Joji he had discerned what his finishing move would be. Elsewhere Ryuki trains in solitude, noting that he would have to break his promise to his grandpa.
