He’s your partner in missions.. Master Tengen puts you together in missions not because of your power but because of how much you hate each other.

You were on a mission to stop the curse, Jogo but you messed up trying to capture him. Toji pin’s you to the wall and aims his blade at your neck “This is our last chance. Mess up one more time and I’ll kill you.” He lets go of you before you and him chase after Jogo
