 they/them 

...or you can just call them Bec or Ceda
    A hellhound away on vacation on Earth, they usually only have one singular head, but it can split and multiply into differing personalities whenever they feel indecisive or conflicted. Each personality is denoted by one general trait or emotion, and while they do often try to resolve any situations by talking them out with each head bringing up their own points, it usually just further escalates the situation beyond any hope of having it fixed.

    Always afraid of causing a scene due to their nature, "Bashful" is their default state, serving as the amalgamation of all other traits present in them. And when those traits do manifest on their own through new heads springing out of their body, it just further embarasses them, especially since the trait in question is "wiped out" in the default head as it then fully embodies into a new head entirely, letting the "Bashful" trait overtake the main head more and more.
