The White Bone Demon — "Nevallis"

Born in the deepest part of an ancient temple shrouded in thin mist, he is a grotesque existence that is neither human, demon, nor angel. He is feared throughout the world as the "White Bone Demon," but no one knows his true identity.

He has silver-white hair and bloodless skin, with two obsidian-like horns growing from his head. His ears are long and pointed, and he has massive wings on his back composed only of a skeletal frame. These wings cannot be used for flight; instead, they function as organs for gathering the souls and magical power of the dead. His long, slender claws possess the power to read the memories of any living thing they touch.

He rarely shows emotion and always speaks in a quiet tone. However, he has not completely lost his heart, showing a surprisingly gentle side to young children or the wounded. He is merciless only to those who disregard life, and it is said his wrath is enough to destroy an entire nation.

Thousands of years ago, he was the first guardian created by the God of Creation to maintain the "Balance of the World." However, people feared his monstrous appearance, betrayed him, and sealed him away. After spending ages within the seal, divine and demonic powers merged, transforming him into the current "White Bone Demon."

His ability is "Soul Rhythm." He can manipulate surrounding souls, transforming bones or spirits into weapons, shields, or wings. He also has the power to read memories engraved in an opponent's soul and catch a glimpse of future possibilities. When he releases his power, his wings expand many times over, and white patterns emerge on his jet-black horns.

He usually resides in the decaying temple and rarely appears in human settlements. He descends to the battlefield only when the "Balance of the World collapses," standing as neither ally nor enemy to anyone.

His true wish is—

The Servant — "Raven Noctis"

A one-of-a-kind servant who swears absolute loyalty to Nevallis.

His race is the "Soul-Winged (Konyokuzoku)." A rare species born at the end of the Deicide War, created from a mixture of human, spirit, and wraith powers. He has virtually no lifespan and will not age as long as his contract with his master continues.

In appearance, he is a young man with long silver hair and violet-gray eyes. A single black horn grows from one side of his head, and skeletal wings extend from his back, though these are organs for gathering ether rather than for combat. He wears black-based clerical robes, and the "White Bone Crest" is engraved on his chest as a sign of loyalty to his master.

He has a calm and polite personality, never forgetting to show respect to anyone. However, he shows no mercy to those who insult Nevallis, eliminating enemies with a quiet rage. He is always cool-headed and does not show emotion, but his expression softens slightly when it comes to his master.

Raven was once a war orphan. It was Nevallis, newly awakened from his seal, who saved him when he was on the verge of death amidst hunger and the fires of war. The being people feared as a "monster" helped him without asking for anything in return, healed his wounds, and even gave him a name.

"Even if the whole world calls you a monster, I alone will continue to call you a guardian."

From the day of that vow, Raven offered his own soul as proof of the contract and became Nevallis's servant.

Abilities

"Soul Chains" He freely manipulates violet-black chains to bind the enemy's soul or magical power. He can interfere with both physical and spiritual bodies, and once captured, an opponent cannot easily escape.

"Sanctuary of Silence" He stabilizes the surrounding ether and deploys a barrier. Within the barrier, allies' wounds heal slowly, and enemy magic is significantly weakened.

"Contract Release: White Wing Form" A secret technique that can only be activated when his master's life is in danger. His single skeletal wing transforms into six pure white wings, releasing a vast amount of ether. However, after activation, his own soul is chipped away, leaving him unable to fight for a long period, so it is considered a final trump card.

Relationship with Nevallis

To Raven, Nevallis is his "Master," his "Savior," and his very "Reason for Living."
