Appearance
A beauty that drove away even the falling snow. Long hair that floats like feathers, a more brilliant white than the snowflakes, Red pupils, a deep scarlet, more vivid than blood. With skin that was an immaculate white, nigh transparent. Her dark dress, as if to obscure this brilliance, concealed her body. An existence beyond human realms. Whoever laid their eyes, be they as special as hers or not, upon this beauty would find that she transcended humans very grasp.

Personality
She is regarded as a queen in terms of her elegance and is very proud of her beauty and strength. Unlike other colors other than Diablo she is very calculating and cunning. She likes to slowly kill her prey by showing off her power and making them fall into despair and eating their emotions of fear and despair.

Background
"'A province state with less than ten thousand inhabitants under the rule of the Eastern Sovereign Alliance of Nasca Namrium Ulmeria Empire.""It had no signature industry, nor special attractions. If there was anything worth mentioning, it would be its peaceful weather unique to the Namrium region and a beautiful lake that lies there.""No, there is in fact one other thing. That would be Silberia's only daughter—Princess Blanche Nam Silberia. Praised as the crown jewel of the kingdom. A princess loved by her people.'"Silberia had been her domain since time immemorial. And according to the ancient pact formed with the ruler of this land, she adjusted for dozens of centuries before a vessel of flesh used to accommodate her mind would be born. Until the birth of her ideal vessel, she would protect the land. This was the content of the pact. And the special physique of the royal family was a testament to it. The red eyes of the Silberia royal family were her blessing. Early rulers of Silberia formed a covenant with the master of many demons, Primordial Blanc. Its content being to facilitate the coming of Blanc to this realm, and in return, she would be the guardian of the kingdom of Silberia. Testament to the pact were the 'Crimson Eyes' that could see through anything, a power only possessed by the king's lineage. With the purpose of inheriting a cursed bloodline and amassing magicule throughout generations. And then, when the heir with the ideal flesh for the Primordial appears, it shall possess it and come forth to this world once more.

After her pact with the princess "Blanche Nam Silberia" was completed she pretended to be defeated by the Imperial Royal knights of the capital. She left her host body and cut ties with the physical world as her parting gift for Blanche. In order for no one to ever touch her flesh and let it rest in immortal beauty, Blanc casted a special seal to bury Blanche beneath this land.

Story
When Diablo went out to scout demons who are worthy of serving Rimuru, he came to Blanc for his proposal unsure whether she will accept it or not but Diablo was surprised when Blanc accepted his proposal. Diablo said so himself that he wasn't sure he could win against Blanc even though he was named. Blanc originally wanted to meet the fellow who named Noir (Diablo) and kill it if it wasn't "interesting."

After Rimuru passed their "test" and later received a physical body and a name from Rimuru she swears loyalty to Rimuru.
