As stated last chapter, They managed to evacuate almost if not all the civilians before the attack so not having time isn't a valid excuse. The fact that being guild member they got know earlier about the attack and didn't take emergency measures to get her to safety means that they kept Asuka with them in purpose. They're aware of the danger yet are endangering their dughther in purpose!
