Description
Eco is the primary female protagonist of the narrative and a unique being, known as a Dragonar. She is a dragon who was born in the form of a human girl, a phenomenon unprecedented within the world's established order. Her most distinguishing physical features are a pair of small horns on her head, which mark her as a dragon, and her long pink hair. She typically wears the uniform of Ansullivan Dragonar Academy, which consists of a white coat with red decorations. In her true form, she is a colossal dragon of immense power, possessing three horns, large white feathered wings, and pink fur, a form so massive it could step on a large battleship with ease.

Eco is characterized by a very strong-willed and often stubborn personality. She is known for being prideful, selfish, and at times, gluttonous, showing a particular fondness for meat and crepes, as well as a love for sleeping in. Her demeanor is frequently marked by a sense of superiority, especially in her early interactions with her partner, Ash Blake. She constantly refers to him as her "dog" while asserting herself as his master. This verbal dominance is a manifestation of her pride and a defense mechanism; she is fully aware that she is technically the pet and Ash is the master, but she fears that accepting this role would reduce their bond to that of a mere tamed animal, which is not the kind of love she desires from him. Despite her outwardly abrasive nature, she cares deeply for Ash, and this is evidenced by her frequent displays of jealousy whenever he interacts with other females. Her behavior can also be childish at times, a reflection of her young age as a newly born dragon.

Motivation and Role in the Story
Eco's existence is central to the story's primary conflict and mystery. She was created by the Mother Dragon for a specific purpose: to mate with her partner, Ash Blake, in order to preserve the dragon race from extinction. This goal serves as her core motivation, even if she does not fully understand or openly acknowledge it initially. Her role in the narrative is not only that of Ash's partner and main love interest but also as a potential savior of her kind. As the story unfolds, it is revealed that she holds a prestigious position as the Imperial Princess within the Emperor Family of the Avalon's Holy Dragons, granting her significant authority over other dragons. The plot often revolves around the attempts of various factions to either protect her, control her, or use her for their own ends, including those who would wish to see her dissected and studied because of her unique nature.

Key Relationships
The most significant relationship in Eco's life is with Ash Blake, her designated partner and master. Their dynamic is central to the series, starting from a point of bickering and her asserting dominance, but gradually evolving into a profound bond of mutual trust and affection. She is extremely protective of him and becomes jealous when he receives attention from other women, such as the proud Princess Silvia and the student council president, Rebecca. Although she calls him a dog, she is, in fact, fiercely loyal to him. Another key relationship exists with a being called Navi. Because Eco is young, her complete access to the Dragweiss, the collective memory of the dragon race, is limited; therefore, this knowledge manifested as a separate personality known as Navi to guide her. It is implied that Eco will eventually absorb Navi to gain her full power and knowledge.

Development
Throughout the series, Eco shows considerable development from a newly born, arrogant creature into a more mature and self-aware individual. Initially lacking a full grasp of human concepts like modesty, she begins to understand and exhibit these traits as her relationship with Ash deepens and her own feelings for him become clearer. Her journey involves learning to control her immense power. After her first awakening in her true dragon form, during which she had almost no control, she was given a special bracelet by the Mother Dragon to prevent unwanted transformations. However, in time, she develops the ability to control her dragon form at will. Similarly, her understanding of her own feelings and her role as both a partner to Ash and a princess of the dragons matures as the narrative progresses.

Notable Abilities
Eco possesses a wide array of extraordinary abilities that set her apart from ordinary dragons. Even in her human form, she has superhuman strength and stamina, capable of easily defeating seasoned warriors. Her sneezes, for example, are powerful enough to send people flying. As a dragon, she can access the Dragweiss, the collective memory of the entire dragon race, and because of her royal lineage, she appears to be the only dragon with complete potential access to this information. She can create powerful magical weapons and armor, known as Arks, for Ash to use in combat and is able to produce a high-level magical substance called Uranos. In her true dragon form, she is acknowledged as the most powerful known dragon, capable of destroying massive flying battleships with a single step. As the Imperial Princess, she holds authority over other dragons, compelling them to obey her commands even against those of their own partners. She also has the unique ability to bestow some of her magic upon another dragon, causing it to evolve into a powerful Holy Dragon Maestro.
