Real Reason

Leonel didn't react immediately. Technically speaking, this wasn't his home, and he also wasn't 100% certain of the ongoing situation. Plus, he and Aina had come here wearing masks, so their intentions to stay out of the spotlight were both clear and obvious. 

He didn't want to get into any trouble if he didn't have to. 

Although he hadn't checked the rules of the city, this was the greater world where the power of an average person could probably level a home without too much effort. In this sort of situation, one couldn't expect the rules to be the same as Earth. 

That was to say that Leonel didn't believe that they had come here because of the fighting, especially since everything had taken place on private property. It was likely that they had already planned on coming to this home from the very beginning for whatever reason, and just so happened to run into this situation.
