"I wouldn't be surprised if you'd already slept with a few girls in Beacon. I hear Huntresses are always the most beautiful women." That might as well have been true, though few realised just why that was. Two simple words, aura and lifestyle. Hunters were fit, well-trained and lithe - but also had aura to protect them from injuries and heal wounds.

It was a lesser known fact that aura also boosted all natural regeneration too, which meant any small wounds but also included things like your skin naturally replacing itself. Which was why Hunters and Huntresses never quite looked as old as they might be, or ended up looking unusually ageless like Ozpin and Miss Goodwitch. Simply put, their skin remained healthy and strong, even as they reached old age.
