—----------------------------------

Appearance

Lucoa takes the form of a tall, voluptuous woman with long, golden-blonde hair cascading past her hips, bright heterochromatic eyes and a warm, fair complexion with a voluptuous, hourglass figure. Her attire tends to be casual and revealing, tank tops, crop sweaters, short shorts and miniskirts, outfits chosen for as much comfort and as for teasing her friends.

Her divine presence subtly radiates warmth and calm, soothing mortals and dragons alike. When she releases her true power, her silhouette takes the form of a blue radiant feathered serpent and iridescent wings.

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

Personality

Warm, gentle, endlessly patient, and deceptively wise. Lucoa rarely raises her voice and often acts more like a doting mother or older sister than a warrior or goddess. But beneath her carefree demeanor lies a millennium of experience, keen insight into emotional dynamics, a deep longing for peace and a desire to avoid repeating the tragedies of her past. She enjoys teasing others, especially Issei and often defuses conflict by redirecting conversations, soothing tempers, or giving subtle emotional guidance disguised as offhanded advice. Though normally calm, certain things break her composure, Gods abusing authority, Dragons losing control, curses that manipulate innocent beings and anyone threatening one of “her kids” and gets easily flustered if her past with her sister is at all mentioned.

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

Background

Lucoa was once revered as the Dragon Goddess of Wisdom, Sunlight, and Fertility, a guardian who guided humanity with compassion rather than domination. Her concept of divinity revolved around nurturing balance. However, she was exiled after a catastrophic scandalous affair involving her sister, where she became drunk after consuming a bottle of cursed liquor resulting in the loss of her divine title and her removal from the High Pantheon. She is a member of the spectating faction, she does not interfere with any events involving the dragons or gods. She has confessed that she hates conflict so much that she will run away at the first sign of trouble without protecting anyone and then acts as if nothing had happened after everything is over, without even caring if any of her friends had died. She is self-conscious of this fact but does not seem intent to change. Now, she wanders as a benevolent being seeking meaning. Her arrival in Japan occurred when she noticed the disappearance of Tohru or Kanna. She quickly went searching for the two and quickly found them on Earth. When she meets Issei Hyoudou, she quickly notices that this boy and the planet to be interesting and new. She instantly noticed the chaotic nature surrounding the boy that went against her peaceful nature but somehow this didn’t cause her to run away and instead wanted to stay. Luckily Issei didn’t mind her living with him and Kanna. She quickly took note of his perverted nature and gladly liked it when he stared at her chest  and made her want to continue to tease him.
