Luna asking the defenders to disclose their traits despite it being taboo among hunters showed how desperate the situation was, but just because she asked it didn't mean they would comply. Learning a hunter's trait was akin to knowing their weakness, not just that but it could also give information about their lineage to those in the know.
The defenders readied for a fight as they were willing to die to protect their secrets, but their leader stepped in and looked Luna in the eye before speaking.
"None of us have a trait that can make people fall asleep or anything related to that."
"That's not why I'm asking. I need to know exactly what kind of trait do you all have." Luna insisted.
"And you think we'll do that just because you're cute?" A bald man wearing the trademark gas mask of the defenders asked with hostility.
"Thank you." Luna said, flattered by what she took as a compliment.
