Faitfore is generally not very expressive and usually only Dust is able to tell when her mood changes. She is very blunt and will often comment on how others smell. She is generally quiet and usually only talks to Dust. She can become noticeably more emotional in matter involving Dust; she cries when she accidentally hurts him, and she growls at people who insult him (particularly Lean). Her eyes start turning red as she becomes angry, and she has a tendency to bite people when she's upset. Faitfore's most notable personality quirk is her massive appetite: despite taking the form of a young girl, she still eats the same as when she is a house size dragon. She's easily bought off with food, though the sheer amount that she eats leaves Dust in poverty even when he takes on lucrative jobs.
