Aida is stubborn yet anxious, refusing to change her mind unless given a good reason. She is prone to taking things literally, not understanding sarcasm or ironic humour, and cares very much about how others perceive her, though she pretends she doesn't. Despite being a vampire, she is hemophobic.

Aida likes anime and draws her OCs in her free time, which she shares online. She has many online friends but struggles to maintain relationships in the real world—school in particular—because of her anxious personality.
