Likes: Basking the sun in the Virtual World
Dislikes: Having to do customer service for Luca

Luca's mind guardian. She refers to herself as her "agent". Because Luca is a Dive Therapist and her "customers" come into the world where Goro lives, she has to take care of them. Because of her cute appearance and contrasting voice, most customers remember her name.
In that sense, she is a celebrity, whether she likes it or not. She's normally a smiling, cheerful, and cute girl, just like Luca. You can see Luca's strong desires in the big gem that she always rides on.
