Safalin is seemingly the most reserved doll. Her first appearance is on a screen in the Monitor Room, and she only emerges in person when Ranger demands it. Afterward, she roams Floor 3, practicing hospitality for "important participants" on orders from the Floor Master, Rio Ranger. Her title, "The Crying Doll", is congruous with the way she acts. She seems to have a rather submissive personality, often allowing others to bully her. She never asserts herself and is quick to apologize for any perceived misstep. On occasion, Safalin seems to be carried away by an unusually brazen and almost sadistic streak, so far only seen when she is meeting one-on-one with a participant. It is unclear whether this behavior is intended to be entirely malicious or not, and what exactly triggers this shift in her behavior. As soon as another individual enters the scene, she quickly resumes her typical behavior.

Safalin's original Japanese name, "ハンナキー, Han'nakī" is a pun on 半鳴き, 'Han naki' literally means "half-crying; verge of crying." vgperson named her Tia Safalin in the translation to make up for the pun; as in 'tears are falling.'
