Luz is Tanner's personal assistant that is often running around at his side. She is very young compared to the other cast members, around age 17. Tanner treats her like his student and adoptive daughter and often entrusts her with some of his work. Luz is also responsible for taking care of the young twins, Miyu and Para, spending time entertaining them or taking care of their day to day needs. Luz's character plays a minor supporting role in the story and is reactionary to the events around her. 

Luz is clumsy and nervous. Her speech patterns tend to stutter a bit now and then and she has a really soft voice. Those auditioning for Luz should be able to do the typical socially awkward and anxious nerdy teenager.
