Why wasn't she afraid of the Kirin Gang at all?
Although nobody wanted to mess with the Kirin Gang, not everyone was afraid of it. In City B, even the Kirin Gang should behave themselves before some people.
For example, the Kirin Gang was reluctant to have a bad relationship with those dominant families and important figures. If it was possible, the Kirin Gang would prefer to build a good relationship with them, because the Kirin Gang had the idea of joining legal businesses. Without the support from the government, they wouldn't be able to do that.

They dared to do that because the person who hired them was more important. Moreover, they protected themselves by only smashing things and not injuring anyone.
