Daphne is very quirky and energetic. She goes long lengths to get her products sold. Daphne often jumps around the room and comes across as highly enthusiastic. When Gray shows up, she speaks to him as if she is his master, and she drops the energetic facade. She has no qualms or morals. She will do anything to complete her research, toying with lives if necessary, seeing how her own town used Hidden to hide from her only for her to punish her town by making the citizens unable to dispel the spell in response. She goes to such extents to made her own Lizardmen destroy each other as punishment for not being able to find the townspeople. Her sadistic nature is best seen when she claimed that she could not possibly imagine the fun she would have in destroying Magnolia. She is also a true narcissist, believing herself a genius and mocking her opponents at each chance possible.
At some point in her childhood, Daphne saw a Dragon flying through the sky. After she saw the Dragon, she attempted to tell her fellow villagers about it, but none of them believed her. After this event, she became obsessed with Dragons and started her own project of creating artificial dragons.
