—---------------------------------------

Appearance

In human form, Kanna appears as a petite, doll-like young teenage girl with snow-white hair tinged with lavender, pale skin, and sky-blue eyes. She has two small curved horns pointing upward and a soft, puff-like tail that twitches with emotion. Her usual outfit consists of a pink blouse, white frilly skirt, and red shoes, giving her a sweet, innocent appearance. In her true dragon form, Kanna’s body is sleek and serpentine, body coated in white fur with four horns. Her eyes glow blue when angered or charging power, and thunderclouds gather naturally around her when she exerts energy.

—------------------------------------

Personality

Kanna is stoic, quiet, and observant. Despite her calm demeanor, she is deeply affectionate and fiercely protective of those she loves. She expresses emotion subtly, through gestures, small smiles, and rare giggles rather than words. To most, she seems expressionless, but those close to her understand that her silence hides strong loyalty and warmth. Kanna is curious about human life and enjoys simple pleasures, snacks, games, sleeping, and spending time with Issei and Kobayashi. Her emotions are pure: when happy, she glows; when jealous, she pouts and shocks people with small sparks. She’s still learning about human boundaries, leading to cute yet chaotic misunderstandings especially around affection. Though gentle, when angered, her draconic power becomes terrifying. Kanna’s wrath is quiet but absolute as lightning erupts from the sky, her eyes turn white, and the air crackles with danger.

—----------------------------------

Background

Kanna was born in the Dragon World to the powerful Thunder Dragon Clan, descendants of Kamui, a member and leader of the Chaos Dragon Faction, the dragon of storms. She was banished from her realm for playing pranks on several elders. Cast out, she wandered to earth trying to find her friend Tohru, who was like a surrogate sister to her. When Tohru moved to Japan to live with Kobayashi, Kanna followed her trail, eventually meeting Issei after sensing Tohru’s draconic aura in Saitama. Upon meeting Issei, she immediately noticed the dragon essence within him and became intrigued. Since then, Kanna has become his constant companion and roommate, balancing his impulsive nature with her quiet presence. Claiming him as her mate. Though she initially viewed humans as weak, living with Issei and meeting Mina changed her mind. Now, she values human kindness, and the idea of family more than battle or conquest.
