Before auditioning for this character, please understand that you may be doing two voices for him.

Nox is a very straightforward individual that likes to tease people. He is very confident and is very much aware that he is good-looking. Due to his confidence, Nox is very flirtatious and knows how to impress or get his way with a lady. 

Nox Noir and Rex Blanc are rivals, and their dislike for one another is not hidden. Nox is an alumni from Gedonelune Royal Magic Academy, and owns a small magical shop in Gedonelune. While at the academy, Nox was a Night Class Prefect that had earned the respect and admiration from his peers. He was mostly like an older brother to many of the students.

As the Phantom Thief, Nox's goal is to collect all of the magical items that his father created in order to destroy them. Nox knows a secret about his father's tools that could potentially be dangerous enough to start a war. In order to prevent this from happening, he seeks to destroy all traces of his father, family, and creations. 

Voice: Mid-high to mid-deep range, flirtatious and possibly confident

Phantom Thief Voice: The voice he uses for the Phantom Thief is his same, regular voice. However, it should be a bit higher and more flamboyant or elegant sounding.
