"Aya, matured into a grown woman. Runs a clinic with Maria out in the mountains." - Mad Father Game Description.

Aya Drevis is the main protagonist and playable character of the game. She is the only daughter of Alfred Drevis and Monika Drevis who lives with in a large mansion that makes up the setting for the majority of the game. In the true ending, she is now an adult who has chin-length short hair and she no longer wears a ribbon. She wears a white apron over a light blue dress. In the True Ending, her true nature is revealed as she continued her father's occupation of making dolls (though she opts for patients with terminal illnesses and uses sedatives so they wouldn't feel any pain, unlike her father). However, the remake heavily implies that this is simply her way of keeping her promise to her mother; that she would "always support [her] father," as opposed to simply her devolving into madness.

Her voice would be mid-ranged to deep, being very calm and relaxed. She doesn't show much emotion at all, which is reflected in the game.
