Dani is optimistic and more socially secure than her brother. She is very confident and considers those around her to be her friends. Dani is normally happy and kind for she sees the bright side of everything and everyone. Despite this certainty, Dani is deeply worried by the lack of control and skill she has in her magic compared to Dorian.

After the incident where she almost got burned at the stake for being a witch, she was unsure where she stood between witches and non-magical people. The events on floating rock furthered this confusion, causing her to abandon her witch roots and attempt to become a "normal" person. However, after the disaster of the castle party and Alex's death, she realizes that witches aren't just inherently bad, making her her even more unable to choose a side. After she witnesses what she believes to be her twin's death, though, she no longer seems to care about sides and is content as an empty shell.

During the 3 year time skip in the story, she becomes cold, distant, and easily manipulatable due to cursing herself, allowing her to forget the pain of losing her loved ones who were lost, due to the witch conflict. However, she later returns to her joyful past self once the spell is broken.
