Usagi Yasuhiro is very calm and collected but also excitable and bright, just like her many paintings. Her watercolor pieces stun and bring joy to critics and the casual fan alike, and create words when she herself cannot. Being mute doesn't stop her creativity and she hopes to bring joy to everyone around the world. After all, art is a field that can be enjoyed no matter the language.

Since Usagi is mute, the 'voice' that she gives is through her sign language, so the words should be spoken as if it's being translated through her signing. As such it's more of a focus on the style of voice rather than the actual sound of voice, but if I had to give an actual vocal range, it'd be higher but soft in tone.
