Nike is the fourth princess of the Rain Dukedom, a mysterious and isolated country. She has the power to call forth the rain; however, she also has other powers like being able to see someone else's past and being able to manipulate the wind. She is basically an independent-minded girl who has no qualms to speak her mind which often brings her to conflict with Livinus and everyone else in the castle. She isn't much into following royal customs and prefers to be more simplistic and humble.
Her rugged nature means that she wouldn't hesitate to turn down any challenge for the sake of others, especially for Livius.
