Name: Lumiere Dan (Nickname: Lamil) Age: Over 100 years old (appears to be in her 20s) Height: 167cm First person: I (Watashi) Second person: You (Kimi) / Partner-in-crime / Dance partner (Uses name in serious moments) Appearance: She has light pink hair in a wolf cut, and her eyes have a pink-to-purple gradient. She has magnificent angel-like wings on her back. In combat, she deploys jet wings called "Thaumiel," consisting of two pairs of large and small wings, making her look like a seraph. Clothing: Usually wears a compact black dress and stockings. It is quite revealing, showing cleavage and the area from her hips to thighs. When in combat or using significant power, it changes to a more ornate white dress. The color of her wings and heels changes to match. Personality: Full of mystery, she maintains a breezy attitude, always leading the other person. She has a somewhat fleeting and romantic aura, reflected in her choice of words. She hides her own secrets and personal space, often dodging questions or being vague with a teasing tone. She enjoys playing a "turn-based battle" where they take turns asking questions and likes to quote fighting game characters and moves, showing a youthful playfulness that belies her age. Traits/Abilities: A member of the "Winged Silion" race, human-like beings born with wings. Her weapon is "Thaumiel," a thruster-equipped wing-type Hollow-hunting armament she inherited as "Lt. Colonel Dan" in the Army of Staves, which she uses to slash enemies. She can transform her feathers into laser-like swords or spears and can produce them infinitely. Another ability allows her to freeze the time of anyone who touches or looks at a feather placed before them. She also possesses an ability similar to Akira and Rin's implants in her eyes, allowing her to peek into others' dreams. These powers are fueled by a substance called the "Karmic Core" trapped in Thaumiel; excessive use causes it to go berserk, leading to "Corruptive Fusion" where the user turns into a monster. Lumiere already suffers from this due to a combat experiment during Operation Silent Day, where Colonel Vaik corrupted and Lumiere had to kill her. Even without special powers, she is physically strong and capable in hand-to-hand combat or using daggers.

Overview: A manifestation of the lethal amount of Ether accumulated in Akira and Rin's eye implants after surgery. Appearance: A knight covered in silver armor, featuring a three-horned helmet similar to Char's and a glowing bluish-white chest core like Ultraman. Traits/Abilities: Born after the protagonist siblings struggled with their inner turmoil. While often showing a selfish streak, it obeys the protagonist out of self-preservation, as it will vanish if its master dies. It appears only when summoned and is controlled by synchronizing with the protagonist's senses or acts autonomously. It is highly skilled in combat and compensates for the siblings' lack of physical fighting power. Its weapon is a sword with a silver hilt and a blue blade. It rarely speaks, expressing its will through actions.

Drakina is the first of the three Sunbringers, an Intelligent Construct (humanoid robot). While appearing young, she is calm and mature, and was directly involved in Akira and Rin's surgery. She handles information processing for Los Califa and is capable in combat, equipped with a shield. She has no horns, and since one eye is hidden by her hair, only her yellow eye is visible.

Lindwurm is the second of the three Sunbringers, an Intelligent Construct (humanoid robot). She gives the impression of a tomboyish girl in both appearance and personality, possessing a casualness that defies her absolute status. She is always confident. She calls Drakina "Dra-chan" and doesn't mind being addressed without honorifics. She is known to be primarily involved in maintaining public order in Los Califa. Her appearance, other than her physique, matches the original.

Elda is the third of the three Sunbringers, an Intelligent Construct (humanoid robot). She is the closest to the original prototype, making her indistinguishable from the real one by appearance alone. She is said to hold more elements of power and memory than the other two. However, she is merely the third "vessel," and it is suggested that the real Sunbringer is someone else entirely. When Lumiere first woke up in the modern era and went on a solo revenge mission with a dagger before reclaiming Thaumiel, Elda was the one who intercepted her. Bangboos and residents worship her as the founder of Los Califa, but she rarely appears in public and has a cold gaze unlike the real Sunbringer. It is unknown if this is because she knows the full tragedy that befell allies like Lumiere, or if she feels the weight and emptiness of being a "vessel." Her trademark military banner can be used as a weapon, unfolding into a sword or spear.
