Victoria/Chronology

Background
Victoria was once known as "The Saint" of the Divine Teachings Holy Church as she preached the doctrine of the Holy Church, as well as the legends of the heroes that defeated demon Diablos. Unbeknownst to her, however, the Cult of Diablos had secretly taken over the church and were preparing to use her in their plans. Unfortunately, one day she began displaying symptoms of "Demon Possession" and turned to her superiors and pray for help, only for everyone who once revered her to repudiate, humiliate and strip her of everything before imprisoning her. With the Cult concluding that they could not use her anymore, she was sentenced to be executed.

On the day of her execution, however, Cid just happened to pass by and saved her using his Shadow persona. Afterward, having become enamored with Shadow, Victoria was recruited into Shadow Garden, where she quickly rose through the ranks and gained a reputation as having abilities at, or near those of the Seven Shadows. Her ability has been increased to such an extent that she was been acknowledged by the Seven Shadows and one day she is expected to become a part of the new Seven Shadows, despite her fanaticism personality attracting too much attention toward Shadow makes her a bit of a loose cannon.

Victoria once challenged 89 to fight her, so she could have the right to challenge Numbers. Knowing that she had just joined the organization recently and the difference in numbers was over four hundred gaps, she shouldn't have a chance of winning. But, she had won an extraordinary victory against her with the power she received from her master, Shadow which gave her the right to challenge the Numbers, even a high-ranking "Named Numbers" member.

At some point, Victoria secretly join Zeta's branch faction with the objective to make her lord, Shadow immortal by reviving Demon Diablos.

Bushin Festival Tournament
In the Anime shortly after the events of the Bushin Festival, Victoria is seen sparring with another member of Shadow Garden (presumably No. 89 in her challenge) at Alexandria, the Shadow Garden base of operations which is the old capital of the Midgar Kingdom.

Oriana Civil War
Victoria took over 664's squad lead them to gather information about the Cult of Diablos' activities in Oriana. Through infiltration and investigating, they found out the Cult had sent 40 First Children to the Fort First at Oriana Kingdom, as it is now in a war torn state.

Victoria called 664, 665 and especially Rose Oriana (666) for the mission since apart from the "Seven Shadows", only Victoria and Rose were given direct power from Shadow. Victoria expressed disdain towards Rose and believed that she isn't worthy of the power she received, telling her that if she becomes a liability for her mission they will leave her behind.

During the squad's espionage in sacred ruins, Victoria sees that Rose's mother, the Queen Reina is involved with the cult. Regardless of whether she was held hostage or not, she lunged at the Queen to take the Black Rose from them, feeling that the ring is the "key" to the mission all the while massacring dozens of Cult members.

However, Rose intervened by attempting to save her mother from Victoria's onslaught. This lead to Rose and the Queen being captured and taken as hostages. The Cult tried to use the hostages as leverage from Victoria's squad but she responded that Rose is unfit to serve Shadow Garden even declared her a traitor for her brash behavior before launching herself at the remaining members group of the Cult "First Children". During that time, one of the Cult’s leaders, Kouadoi the Gale sent Rose and the Queen to Duke Doem at the capital.

In the end, the Cult group was almost eliminated. However, Victoria and her team sustained severe injures and exhaustion as a result of her onslaught. Victoria was nearly killed by Kouadoi who survived when Shadow intervened to finish him off. Shadow asked Victoria to explain what happened, to which she briefed him in a infatuating way on what had happened before telling him that 666 had betrayed them. Believing that he was seething for her betrayal, Victoria tried calming him down but in reality, Cid was confused to who exactly was 666.

Later, Victoria and her superior, Epsilon discuss about Rose's situation and the queen's involvement in a Oriana branch of Mitsugoshi. Epsilon understood her brash behavior and took partial responsibility for keeping her in the dark however, Victoria insisted that she betrayed them and that Shadow disposed her. Epsilon retorted that he did not do anything to her before they dwelled on what burden their master carries. They returned to the report to confirm the Black Rose's legitimacy and retrieval before being once again derailed by their master's sudden appearance. The two were affectionately startled by him and competed to see who they can delight him. Cid revealed that he figured out the problem and that he'll get rid of the root in a day.
