Raphael originally intended to insist on chasing Dragon God away somewhere else, but he could also see that she would never agree to it. So that's why he gave her a 'way out' that was barely good enough to invite her to back down.
"You can find them and fight as many times as you want. Fight until you're about to die, then stop. Consider it a kind of trampling or torture if you want. Of course, if you don't agree, then I'll have no choice but to kill you."
He pointed the tip of his sword at her. It was clearly a deliberate compromise, but he acted as if he were the one with the most decision-making power here.
He didn't know how many of her subordinates were at the demigod level, but there must be at least three such existences for her to be that confident. So Raphael also didn't want to escalate the tension with her too much.
Moreover, in some strange way, he believed that if she just beat up Leo a few more times, the relationship between the two sides would become close.
