The moment Azrael had saw Rose approaching while dragging the almost-dead Claudia, his instincts screamed that he wouldn't stand a chance against her in a head-on confrontation.
Although she was weaker than Harris, Azrael himself was completely exhausted after using the Tyrant's Intent to kill Harris.
In his exhausted—completely powerless state, he wouldn't last even half a minute against Rose before his body gave up.
Moreover, even if he were in perfect condition, it wouldn't have been easy for him to face her.
He was certain that the reason Rose had been able to injure Claudia so severely without receiving any injuries herself was because she must have launched a surprise attack on her.
Since Claudia was familiar with Rose, she likely hadn't expected the attack and was caught off guard, resulting in her serious injuries.
Even though Rose eliminated Claudia without getting even a single scratch was because of surprise attack, Azrael knew she wasn't an easy opponent.
