Seems like Krusche being this cute is slowly making everyone fall for her, men or women no matter, the power of cuteness and her delicious ass is over 9000! If left alone to her devices Krusche could be an harem protagonist herself, since she has to ability to make everyone fall for her.
Also I'm glad Lucas wasn't going to let the noble off the hook, after the dragon burned their magic cloaks and was preparing a second fire attack Lucas simply hid behind Aria to protect himself meanwhile watched as the noble asshole his two goons were defenseless and were going to be burnt alive by dragon and Lucas wouldn't move a finger to save them.
He only took action after Krusche selflessly decided to shield the three assholes and even then tried to punish them, only halting because he respected Krusche's wishes to not punish them, instead he gave them a ultimate warning: "If you ever go after our group again, there won't be a next time".
