Kanna appears as a stoic girl who rarely changing her facial expression or raising her voice, but she is actually very emotional. While young by dragon standards, she is more mature than her apparent age would suggest, and when angry she can be foul-mouthed and rude.

Despite her age, she carries the innocence and affection of a younger sibling. She is compassionate and caring, with a fierce loyalty to her older brother. Her love for him transcends typical sibling affection, manifesting as a deep, complex emotion that she struggles to navigate. She's also curious and somewhat playful, though her vampiric nature often makes her feel isolated from the world of mortals.
