Rose Oriana/Chronology

Early Life
Rose was born as the daughter of King Raphael Oriana and Queen Reina Oriana. During her childhood, Rose accompanied her father to the Midgar Kingdom, sneaking out of her inn to play with the other children. But due to her extravagant clothes, she caught the eye of bandits who kidnapped her for ransom when the bandit realized her identity. But before they could take action, Cid, under the guise of the "Fancy Bandit Slayer," appeared and killed them all, saving the distressed princess in the process. Witnessing the fight, Rose became enamored by the sight of the mysterious figure's swordsmanship, spurring her to develop an ideal swordsmanship built around the basics without any wasted moments.

Due to the traditions within Oriana royalty, she was required to take up an art form. Despite her country's negative opinion on the subject, Rose still chose swordsmanship as her art form to specialize in and strived to prove her country wrong in believing that swordsmanship was uncivilized. Becoming a teenager, Rose entered the Midgar Spellsword Academy as an exchange student, where she would later become Student Council President and a powerful swordswoman surpassing Iris Midgar.

Midgar Academy Terrorist Attack
Entering the Bushin Festival tournament, she first encountered Cid Kagenou in the preliminaries and dominated the duel with her vastly superior skills, overpowering the boy. However, he refused to yield and impressed Rose with his seemingly unyielding willpower. When she chose to finish the fight in one final attack, the referee stepped in before she could launch her attack and concluded the duel. Despite her triumph, the event left her developing respect for Cid.

Following the tournament, the Midgar Academy was besieged by figures clad in black, claiming to be Shadow Garden. In an attempt to defend herself, Rose stood up to the assailants but failed to notice the disappearance of her magic, prompting Cid to intervene to protect her. Seemingly sacrificing his life to save her, Rose was astonished by his actions, interpreting them as his unwavering 'love' towards her, and mourned over his death as she vowed to avenge him.

Rose later discovered Cid survived and found him unconscious in a bed at the school infirmary with his sleeping friends nearby. Happy by this, she thanks him for saving her and says he has earned her love.

Sanctuary Infiltration
While at the train station, she bumped into Cid and discovered he was going to the Holy Ground as well, eagerly suggesting that they go together. On the train ride, Rose held onto Cid's hand while voicing her affections for him, saying that they would overcome the adversity that their "relationship" would bring, though Cid is clearly dismayed by this and tried to shake her off to no avail.

At night, she tried to sneak into his quarters to sleep with him but was disappointed he was absent, when really he was hiding on the ceiling asleep. When they arrived in Lindwurm, Rose gave a tour for Cid before bringing him to a spot book signing by her favorite author Natsume Kafka. After getting a copied signed, she was puzzled by the uniquely signed copy Cid received, but concluded it was of interest to him.

Come the day of the "Goddess's Trial", Rose was in VIP seating with Alexia and Natsume beside Acting Archbishop Jack Nelson. When Cid was called upon, Rose was aghast when Shadow appeared instead, and witnessed his battle with Aurora in anticipation. When he claimed victory against the "ancient warriors", Rose saw Shadow Garden arrive and take control of the portal into the Sanctuary, taking Natsume hostage. However, as Alexia refused to sit idly by, Rose followed the Midgar princess out of concern and joined her and Natsume inside the Sanctuary.

Inside, Alpha guided the princesses as she revealed the Cult's origins along with the truth of the ancient hero, Olivier. When Nelson revealed his immortality and true allegiances, Rose was stunned to see him battle Delta next but soon grew pitying the villain, fighting a berserker with no technique. Once Shadow Garden attained all the intel they sought, Alpha opened an exit and allowed Rose to leave with Alexia and Natsume.

Outside, the three saw Shadow's magic annihilate the Sanctuary and flood the Lindwurm. Concluding they were ignorant to the true battle, the three women swore friendship and a sharing of resources to learn what they could.

Bushin Festival Tournament
Rose had received word of her father will visiting her with the presumed intention of taking her home for an arranged marriage. Although she attempted to convince her father to allow her an engagement with Cid, unfortunately, things took a downward spiral upon uncovering the truth of her father being brainwashed by her fiancé, Perv Asshat, and that he planned to use her father and her to take over the kingdom. She tried and failed to stop his machinations, but was forced to escape after it failed.

As her symptoms from Demonic Possession worsened, she escaped into an underground tunnel where she heard the melody of "Moonlight Sonata." Following the tune, she reached a ruined cathedral and found Shadow playing the piece, who offered his power as if he knew the difficulties she was experiencing. Accepting his proposal, the man disappeared with her pursuers closing on her tail. Rose defeated her pursuers with her newfound power, before her friends Alexia and Natsume emerged to question her actions upon discovering her in the ruined cathedral. Met with no choice, Rose fought against the obstructive Alexia, overwhelming her friend with her now superior strength and magic.

Reaching the tournament grounds, Rose confronted her father and apologized to him before assassinating him, ensuring that her kingdom will not become a puppet state for the Cult of Diablos. At that moment, she accepted her fate and attempted suicide, but Shadow intervened and saved her once again, allowing her to escape. When she found herself alone in a forest, she was discovered by Alpha, Shadow Garden's second-in-command, who presented Rose with two choices: fight alone or join them. Reminiscing Shadow's determination to thwart evil, she decided to trust him and join the organization.

In the anime following the light novel, she was taken to Alexandria and immediately renamed to Number 666. In the manga, she just joined at the end of the Bushin Festival arc, and already become a Number by the Red Moon Incident.

Red Moon Incident
Rose continued in Shadow Garden under the codename No. 666, was assigned her first in-the-field mission to research Demonic Possession and Progenitor's blood utilizing the vast library beneath the Crimson Tower, under Beta's command accompanied by her squad leader No. 664 and teammate No. 665. In the underground library, she met Cid's sister, Claire, and the Ancient Vampire Hunter, Mary. Discovering from Claire that her brother was 'kidnapped,' she instantly erupted in questioning to confirm Cid's safety, despite orders to stand down. After they departed with the duo, Rose was immediately chastised by Beta and her squad members for her outburst.

Afterward, she participated in the battle against the Vampire Progenitor, the Blood Queen Elisabeth. No. 666 and her squad tried their hardest to fight against the revived progenitor, but they were all powerless in the presence of the immortal vampire and were subsequently knocked unconscious. Awakened by Beta later, Rose noticed that all her wounds were healed and that the Crimson Tower was annihilated to mere rubble. Following Beta's orders, she returned with her squad back to their headquarters.

Great Trading Company Conflict
Under Alpha and Gamma's orders to investigate the origin of counterfeit bills, 666 joined 664 and 665 for the mission, with squad leader 664 chiding 666 for needing to keep her focus as she had been distracted. Upon arriving at the warehouse where the counterfeits were distributed from, 666 was the first to notice the magic steel threads and warned her teammates to halt.

It was then they encountered John Smith and 666 was immediately subdued by steel threads she didn't noticed until it was too late. After 664 and 665 also failed to do anything against their masked enemy, the trio were completely immobilized and at his mercy. With a long pause and no action against them, John Smith let them go and ordered that they deliver a message to their leaders to not trifle with him. With no further recourse, 664 ordered the group withdraw and they gave their report to Alpha, who did not punish them for the failure and instead dismissed them from her office.

Oriana's "Black Rose" Civil War Wedding Incident
Rose's team's next assignment was to travel to Rose's kingdom, Oriana, and aided No. 559 to the recover the "Ring" which is the key to the Black Rose which was hidden within Fort First. Upon arriving at the fort, Rose was shocked to see her mother amongst the Cult of Diablos's members. Before she could comprehend, Victoria leapt in and started slaughtering the enemy mercilessly. Just as Victoria was about to cut down Reina, Rose protected her mother from the attack. Rose and Reina were taken away by several cult members.

With her mother now a hostage of Perv Asshat, Rose was forced to take part in a marriage ceremony between her and the evil man. Suddenly, Rose encountered Cid Kagenō at her room. Believing that Cid had came for her, Rose lied to him that she was going to marry Perv and tearfully begged him to leave. For a while, Cid reluctantly complied. Later, Rose received an unexpected visit from Shadow who took Rose to see her mother. At the room where her mother should be in, Rose discovered the truth that her mother was a traitor and had been in league with Perv the whole time. Rose collapsed in shock before Shadow brought her back to her room.

Having no allies to save her kingdom and rendering her father's sacrifice for nothing, Rose succumbed to despair. Suddenly, Rose heard the piano playing and found Cid once more. Rose contemplated in begging Cid to take her away and the two could hide and start a family together. Cid inspired her to find what she cherished most and sacrificed everything for it. After Cid left, Rose found a 'ring' which she believed Cid wanted to use to propose to her. Now realizing what she loved most was Cid, Rose knew what she had to do.

When the wedding ceremony began, Rose declared in front of the masses that she refused to marry Perv. Rose revealed the ring which activated and unveiled a recording of King Oriana who exposed Perv's crimes and entrusted leadership of the the Oriana kingdom to his daughter. Rose then clashed against Perv and easily defeated him but this victory didn't last when Mordred arrived, killing Perv and Reina Oriana much to Rose's horror.

Rose would defend her kingdom from the magical beasts summoned by Mordred through the "Black Rose" and to her surprise and relief, Shadow Garden arrived to turn the tide in Oriana's favor.

Rose watched Shadow and Beta enter the Black Rose before finding the ring Cid gave her, now broken.
