Fight to the death
Azrael is at the point where he can't contain his anger toward his hallucinations. This hints at the inevitable return of Bruce Wayne as Batman.
As Azrael fights, his thoughts turn to St. Dumas while his anger turns to criminals. He is no longer Batman, but an assassin. He is as impulsive as ever, killing people he considers "enemies of the order"
Batman is in a dilemma of his own. As the Tengu, Bruce cannot complete his training until he kills the Aikido master.
Azrael must decide whether to kill an unnamed Cable (X-men) lookalike, and Bruce must decide whether to kill the sensai or not.
Azrael choses death, while Bruce choses pretend to kill the sensai rather decide whether to actually kill him or fail his training (true to form)
