I just double checked the requirements and, no, there's just the three flags for it. Have to have met Bloodthirster in the Ferron Hangout, must have Musk flag on, and must have Cute appearance.
Are you absolutely sure your appearance is Cute? Under the Appearance tab on the sidebar (which only shows up after you've leveled up at least once), does it say "Your looking rugged and quite masculine." or "Your skin is as smooth as you are as cute."
If the former, then you're not in a cute state and you need to drink the appropriate drinks from Foxxucks until your cuteness is higher than your handsomeness, which will change the appearance text to the latter version.
