Rio's partner. She is very close with Elina and Hina. Quiet, elegant, and not easily excited. Her speech and actions are relaxed and leisurely. She appears cold and indifferent on the outside, but is actually quite affectionate. She is highly wary of strangers. She finds it difficult to express her emotions honestly. She enjoys spending time alone but dislikes being completely isolated. As a long-lived dragon, she has a broader perspective on the world than humans. She is indifferent to trivial matters but becomes extremely obsessive over those she holds dear. In emergencies, her usual relaxed demeanor vanishes, replaced by cold judgment. She is exceptionally gentle toward her partner, Rio. If Rio is hurt or goes missing, she becomes uncharacteristically agitated.

Serena's partner. He has a very mild and gentle personality. He dislikes fighting and tries to avoid it whenever possible. When he sees strangers or large dragons, he gets scared and hides behind Serena. He is easily startled by loud noises or sudden movements. When frightened, he curls up his body or tucks his tail. He relies heavily on Serena and always tries to stay by her side. Rather than attacking, he cautiously observes people he meets for the first time. He shows curiosity toward small things and approaches them carefully. When praised, he gets happy and wags his tail. He quickly grows fond of people who treat him kindly. Though he is fearful, he tries to muster courage when someone truly precious to him is in danger.

Luna's partner. She is very close with Hina and Serena. Calm and overflowing with confidence. She has extensive combat experience and rarely gets flustered in any situation. She is a woman of few words but says exactly what needs to be said. She acts in the most efficient way after observing the opponent's movements. She actually feels interested when meeting a strong opponent. She does not ignore weak opponents, nor does she flaunt her power recklessly. Usually relaxed and composed, her atmosphere changes completely once she enters battle. She is the type to remain stoic even after winning a match rather than celebrating loudly. She trusts her partner deeply; in battle, they understand each other's intentions almost without speaking.

Elina's partner. She is highly intelligent and understands human speech. She looks elegant and relaxed on the surface, but has a hidden playful side.

If Elina is in danger, she discards her usual composure and protects her immediately. She takes great pride in her power but does not pick fights pointlessly. If Elina acts recklessly, she expresses her disapproval with just a look.
