Roses of Vox

The Roses of Vox are white or silver colored roses used in Noble's castle for instant communication. They grow around the castle and Clarice can use it to make announcements by breaking off a rose bud and filling it with Yoki, causing it to bend around her ear and move its flower to her mouth to "record" her voice. This can also be used for private communication with others, even outside the castle if said others have a rose "headset" themselves.
