Here’s a little Kazumi of the Crystal Clan, Draconik Major’s late lead singer. Her element was ice. She was also able to control wind. The Crystal Clan is somewhat related to the Storm Clan (as the Crystal Clan can create cold storms), so Kaz and Nariko were particularly bonded. She taught Nariko, Ryuu, and Teddy the art of music, but she groomed Nariko specifically in refining their voice.
She had a calm yet commanding personality. Little is known about the circumstances of her death other than her body was found in the wilds beyond the city. It’s assumed a Feral attacked her, but Kaz was a powerful elder dragon, so this theory is suspect
