Thanks for the chapter!
Betcha dollars to doughnuts that the dragon girl is the next waifu for the MC to contract with. Be interesting to see how she fights and how the duo beat her. As for the tightlipped victims most likely they're keeping their mouths shut because embarrassed to have been beaten by a young girl even if she is dragon kin. Would be a hoot if she turned out to be the top ranked dragon's daughter or a princess or something and MC's face finding out the hard way when daddy comes by hearing his daughter got taken away by a man.
