Testarossa

Testarossa (テスタロッサ), also known as Blanc (原初の白). She is one of the Primordials that joined Tempest after Diablo recruited them.

Appearance
She is an alluring lady with white hair and crimson red eyes. She usually wears a black military uniform with baggy pants. Her formal attire is a teal-colored dress. Out of the 3 Primordials recruited by Diablo, she is the tallest.

Personality
She is gentle but also cruel. She is very egocentric and gets mad easily.

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.

Chronology
She was recruited by Diablo who was looking for subordinates to help out with chores. At first, Rimuru thought she wasn't strong but Raphael quickly corrected him. She was excited to meet Rimuru and hoped he would accept her. After changing locations the unnamed Testarossa gained a physical body by fusing together with an Emulated Soul and inhabiting one of the many bodies in the growth capsules prepared by Rimuru. He modified Testarossa's skeleton and mixed gold into it, further improving the body. After she gained the body, Rimuru named her along with 2 of her servants and 200 soldiers. The 2 servants were named Cien and Moss. Testarossa and Moss evolved into Demon peers from being named while Cien evolved into an Arch Demon.

A bit later Testarossa was assigned with being the Military Attaché, a representative for the Western States Council. Testarossa accepted it with a gentle smile promising there would be no problems.

While Rimuru was in Ruberios a Western States Council meeting took place. The meeting was in a huge crisis due to the main defense force of the Sidel border region disappearing. The demons from Guy's territory could easily run down Ingracia like this. The emergency force to defend the country would be handled by Testarossa which was an unanonimous decision but there were still complaints. Testarossa calmed everyone and asked Moss to report the situation to everyone in the meeting. After this the council members begun arguing which Testarossa listened to quietly. During this she eavesdropped on Johann Rosteia, the duke of the Rosteia Kingdom, who was using Magic Communication to give orders to disrupt the barrier around the city. She confronted Johann but was interrupted by the Apostles of Vert who summoned the Green Primordial, Mizari. After Mizari arrived she confronted Testarossa but in the end retreated and said she would fight Testarossa the next time they meet. With this everyone in the council learned Testarossa's true identity as the White Primordial but she also conquered the Western States Council and became highly influential in it.
