Camille's younger brother, Stivan, was born too weak to take on this responsibility. Her parents, especially her father, were immensely proud to see Camille replace Stewan as chief agent. As Stewan saw that his sister had received more instruction and training, jealousy began to grow. Camille becomes increasingly adept at fighting, stealth, and interrogation. Her favorite fighting techniques are fighting with the leg blades from Shanzan, using classical inquiring techniques to gain information, and practicing rappelling with hooked ropes from a dilapidated bell tower, a suit from the western Python Islands.

When Camille was twenty-five years old, she and her father were attacked by a gang of gangsters who had undergone augmentation surgery. These people want to make their way through the underworld of Zu'an, and they feel that the secrets of the Philos family are profitable. Camille and her father were both wounded. Although she eventually recovered, her father died. Camille's mother could not bear the grief that would upend the family, and soon followed him. The position of head of the house eventually passed to Stivan. He was young, eager for quick success, and determined to prove that he was a powerful leader of the family, so he doubled down on research into the enhancement of human Hex's technology.

After a full year of mourning, the Philos family put on the lights and ushered in another day of evolution for the interview ceremony. Stivan personally chose Hakim Nedri as the head mechanic in the house. This promising young man was a crystallographer from Bergunn, a small coastal town of Shurima.

Camille has always felt guilty for not protecting her father, so she asks Hakim to perform a hex-augmentation operation on her to push the limits of what a human cannot overcome. When Hakim first met Camille, he was already in love with her. Hakim was determined to bring Camille out of the shadow left by the death of both his parents. The two worked together and shared folk tales from the Shurima Desert at night, and their friendship grew stronger. After months of intimate work, Camille finally had to admit her feelings. As the date of the surgery approached, their relationship became more and more inseparable, as both knew very well that the completion of the surgery would mean their separation. Hakim will move on to other family projects, and Camille will once again devote himself to his duties as an agent. In addition to this, Hakim was more worried that when he cut Camille's heart, he might cut too deep and destroy her humanity as well.

A few days before Camille underwent surgery, Hakim finally couldn't take it anymore. He proposes to Camille and begs her to elope with him. He depicts a future in which the two of them walk on the sunny sands of Bergunne, excavate the ruins of ancient Shurima together, and raise their children together...... The family responsibility that bound Camille will no longer exist. For the first time in her life, Camille was shaken.

Stevan's position as head of the family largely depended on Camille's ability to execute. When he heard about the secret proposal, he realized that his chief agent could leave at any moment, and his power in the family would be lost. Stewan devised a ploy to remind Camille of the vows she had made in front of her father. When he learned that at one point Camille was going to meet Hakim, he arranged an attack against him. Although his weak body made it difficult for him to achieve his ambitions, as Stivan struggled in front of his sister with a blur of flesh and blood, the helplessness and dark memories of his inability to protect his father all came to Camille's mind. Camille couldn't turn a blind eye to the blood on her hands—that's what happens when an agent gets distracted.

Hakim begged Camille, but she was not blessed. The responsibility of the secret agent is passed down from generation to generation, and if she is always vigilant, her father's life and her brother's safety will not be lost. Camille insisted on surgery and eventually severed ties with Hakim.

Hakim still loves Camille, and he knows that no one but himself can get the operation done properly. In order to prevent his lover from dying on the operating table, he agreed to Camille's request and gouged out her heart with his own hands. Once he was sure that the new mechanism would work on its own, Hakim left the Philos house. When Camille awoke, she saw that the lab where she and Hakim had worked together had long since been empty.

Camille threw herself into her work, strengthening her blades, hooks, and other devices. With each improvement, it is not only the limits of Camille, but also the frontier of technology. This makes many people wonder how much human part is left in this young lady. As the Philos family grew in wealth and power, so did Camille's mission for Stivan.

Thanks to Hextech's artificial heart, Camille is immortalized with no trace of the passage of time, and Hakeem Nedri quickly becomes a distant memory. However, time was not so lenient with her brother. Stewan's body grew weaker, but he held on to the position of head of the house more and more firmly.

During a recent mission, Camille breaks the doomed marriage of a naïve Leather City girl, but a series of twists and turns reveal Stevan's betrayal. The lie that had driven Hakim away now threatens the fate of Camille and the entire family. She finally saw his greed and scheming. This utterly selfish soul has long since put the interests of the entire family behind. At that moment, she finally let go of the last trace of her feelings for her brother and completely controlled the authority of the Philos family.

Now, Camille has her favorite great-niece as the head of the house, and behind her back, she directs how to deal with public affairs. This allowed Camille to continue her more secretive activities and protect her family in the shadows. Camille sees herself as an expert at solving tough problems, so she doesn't mind physical makeovers and sharp criticisms. The energy of the Hexcrystal surged through her veins, and she was never satisfied with being at home. Instead, she enjoys orchestrated espionage operations, freshly brewed tea, and long walks through the haze.

The first sound I heard was the sharp scraping of metal against the stone. I was dazed, still immersed in the hazy darkness, but deep in my consciousness I recognized the voice: it was a blade cutting through a damp pebble. It's exactly the same as the file of my stonemason making quarrying marks on the cliffs. I was so nervous that the roots of my teeth trembled. I struggled to break free from the rope around my wrist as the fog cleared and the only thought left became clearer:
