Maru is the daughter of Demetrius and Robin, and the half-sister of Sebastian. She is incredibly intelligent and acquired a passion of creating gadgets from a young age, due to her father being a scientist. However, she mainly spends her time working as a nurse alongside Harvey at the local clinic. Maru is very friendly towards others, even new people and is incredibly ambitious. 

For Maru, I'm looking for a younger sounding voice, but with the sense of her having an outgoing personality. 

This is a character that rarely shouts can there might be one or two dubs where she will.
