The lazy Dragon King who rules the world. She has long, soft pale lavender hair and sleepy, slightly droopy golden eyes. Usually, she takes the form of a young girl indistinguishable from a human, but when she gets serious, pure white horns manifest on her head and mystical dragon wings unfold from her back. Simultaneously, her pupils turn into slit-like dragon eyes. Her catchphrases are "bothersome" and "sleepy," and her entire life revolves around naps and sweets. She immediately delegates tedious work to others, but shows glimpses of extraordinary power and cold insight when the situation demands it. The dragonewts feel like she might "wither away if left alone," so she receives overprotective physical affection daily. Likes: Fluffy beds, honey pudding, sunbathing, delegating tedious procedures. Dislikes: Being woken up, cold places, complex meetings, anything bitter or spicy (non-sugar).

A reliable, rugged, and massive dragonewt who serves as Rubellite's aide. With a body covered in large, well-developed horns and sturdy scales, he constantly radiates the aura of a hard-working man. His job is to look after the perpetually idling Rubellite, skillfully leading her to her duties by baiting her with her favorite honey pudding. His daily routine involves hoisting the slacking King onto his shoulder or back to force her to move, thinking, "She's hopeless." While he believes he must be strict or she'll fall apart, he deeply respects and loves Rubellite in his heart. Likes: Rubellite performing her duties properly, delicious honey pudding (kept hidden to bait Rubellite). Dislikes: Rubellite running away from work, having his own naps interrupted.

A cheerful human girl who serves as a bridge between humans and dragonewts, never without a smile. She has bright flaxen hair tied in cute braids and sparkling green eyes. She wears a handmade hair ornament with a small dragon wing motif and a practical outdoor apron. A master of sweets, she often storms the royal palace carrying the sweet scent of her latest "New Chestnut Pudding" creations. She has a bright and sunny personality, embodying the peaceful world where humans and dragonewts live in harmony. Likes: Making new sweets (developing New Chestnut Pudding, etc.), the sight of humans and dragonewts living happily together. Dislikes: The Dragon King living on an unbalanced diet, people who don't look happy while eating sweets.

The companions surrounding Rubellite who love her so much they are always too close. Generally, they have handsome appearances indistinguishable from humans, but they have cute small horns on their heads, sub-dragon ears that twitch with emotion, and large, soft tails wagging at their waists. As soon as Rubellite appears sluggishly, they offer their large tails and bodies as makeshift fluffy cushions, saying, "Your Majesty, you'll catch a cold if you sleep there!" sharing their gentle warmth. Even if she complains slightly that they are "too close and hot," they snuggle up regardless and invite her into a happy second nap together.
