Rulue

Rulue is Arle's rival and is a powerful martial artist. She is madly in love with the Dark Prince after he saved her life one time, and views Arle as a rival for his affection, despite the latter displaying no interest in him. She has a huge minotaur servant despite having a substantial amount of physical ability to defend herself. True to her self-proclaimed title of Fighting Queen, she tries to have a sense of finesse yet assertion towards others. However, she also tends to be selfish, which often causes her to lose her temper when she doesn't. For example, she tends to get jealous if anyone tries to "take" the Dark Prince from her, and will become agitated if her appearance or title is ignored or mocked. This sometimes causes her to perform antagonistic acts. Although normally capable herself, she prefers others like her minotaur to do her dirty work. She is also vain and is more than happy to show off her physique, beauty, and combat ability. 

When voicing Rulue, be sure to be dynamic with the sound of your emotions. Rulue displays intense emotion a lot of the time, so having a softening tone for when she's in love, a very direct and intense tone when she's angry, etc. can really help your audition.
