Sora

Appearance
The books describe her as a girl of asian appearance with the physique of a ten years old child. She has blue hair that goes down to her neck, golden eyes, and pure white skin. In her partially transformed state, she grows two slightly curved horns, a tail, and wings.

Personality
Becoming the dragon king's familiar stopped Sora's physical and mental growth. She still keeps the ability of accumulating experience and knowledge but her personality remains that of a child.

Completely loyal to the dragon king, who for her is her master, teacher and the father that raised her. For Sora, the dragon king is the strongest and her most adored existence, she has a wish of proving herself the existence he can rely on the most and being seem and treated by him as his own child. She seems to have a dependency on the dragon king that seems to manifest in the form of a father complex, she seems to resent Lina because she is the woman who took the dragon king away from her.

History
Sora was originally a human child, when she was just about to die in a war one thousand five hundred years ago, the dragon king saved her life turning her into his familiar. After that the dragon king picked her up and raised her just like his own daughter. Sora spent the next five hundred years living alone with the dragon king and helping him with his duties and with protecting those who he decided to protect as his familiar. After the dragon king and Lina saved the Yagumo region from the army of monsters attacking it, she was asked by the dragon king, who was just about to depart alongside Lina to the Stralh region for ending the divine war, to protect the Yagumo region in his absence.

Unable to forgive the people who despite being helped by the dragon king blamed him, chased him away and forgot him, Sora decided to create the legend of Ryuo and educate the king of that time into making him spread the tale through the Yagumo region, the contents of Sora's education stay unknown, Rio decided to not to ask about them when he met Sora.

Until Rio summoned her, Sora spent the next one thousand years alone in a hut at the summit of a ten thousand meters high mountain located in the limit between the Yagumo region and the wilderness, with just fulfilling her last order and not letting the last person who really remembers the dragon king to disappear as her only reasons to live.

Now that she reunited with the dragon king reborn as Rio, Sora decided to serve him just like she served the past dragon king.

Abilities

 * Infinite magic power: Her condition of familiar gives Sora an infinite supply of magic power from her master.
 * Infinite lifespan: Her condition of familiar made Sora biologically immortal. She cannot die from illness or old age.
 * Tough body: Being the familiar of the dragon king gave Sora a body resistant to illnesses and adverse conditions.
 * Dragonification: Becoming a familiar changed Sora's race from human to dragonman, an existence that possesses at the same time a human physical body and a dragonoid spiritual body, if Sora materializes partially or totally this spiritual body she can turn partially or totally into a dragon, while dragonified Sora's skin can repel magic power.
 * Master-servant bond: No matter the distance Sora can feel her master's presence and location.
 * Summoning: If she is given consent Sora can summon her master to her location.
 * Spirit Arts: As an existence that is partially a spiritual one, Sora can use spirit arts as a matter of course.
 * Summit of the draconic species: As a dragonman that was also the dragon king's familiar Sora is instinctually feared by draconic creatures, no draconic creature will ever have the guts of attacking her.

Relationships
Rio: Her current master, she respects and loves him as much as she loved the past Dragon King. As Sora described Rio to Celia in volume 22, the Dragon King will always be the Dragon King regardless of his rebirth. When indicating Rio's personality and actions were the same as Ryuo's from a thousand years ago.

Ryuo: her master, teacher and the father who raised her.

Aishia: A companion she begrudgingly accepts and acknowledges given Aishia's origin as being created by Lina.

Lina: Sora seems to resent Lina as the woman who took the dragon king away from her, but before that their relationship seems to have been good enough for Lina to not mind teaching Sora about her authority, her research topics, letting her meet her familiars, letting her into her secret lab and entrusting them with things like the masks she gave to Rio.

Ayase Miharu: Due to Miharu being Lina's reincarnation, Sora is extremely cautious of her. While Sora does not hate her, she keeps a distance from her and doesn't allow Miharu to close that gap. In volume 22 when pretending to be a lost child introduced to the group by Celia, Miharu is the only person in Rio's mansion who Sora calls by her full name the entire time. An action that frustrates Miharu. Sora also is observed to be uneasy receiving any good will from Miharu.

Trivia

 * Sora speaks in the third person. Whether this is because she is still mentally a child or a mannerism she had previously is unclear.
