First of all. that dragon just came down to exterminate 3 little pests? He could just have ignored them. But, okay. They do pose danger to him, as that battle nun/knight jst cut his entire wing off. She did cut through that bone, right? I could see the sky through that gaping cut. That wing was just held together by the patagium (flying membrane). Also keep talking, while that dragon struggles to get free instead of, well provoking a flamebreath attack in one direction while the other one attacks, which was all the talk about, what is kinda unnecessary as it is the most basic plan, that anyone would use without talking about it...this is not the best chapter of this serialization.
I'd wish the authors would upload their mangas here before they get printed in japan. This way they would have other people then the editors to point out flaws. 😆
