Claire Kagenou/Chronology

Early Life/ Training and Youth
The eldest child of the Kagenō Baron family, Claire is the daughter of Mr. and Mrs. Kagenō and had always wanted a little brother. At the age of 2, she got her wish when Cid was born and was escatic to see her new baby brother. Around age 3, she got herself into trouble on occasions as Cid pulled her back when she once almost accidently knocked a pot of boiling water on herself, when a stray dog nearly bite her, when she was about to fall out of a window, and cried when she got lost in a forest. Cid despite being a year old at the time, saved and protected her on several of these occasions without knowing consciously it was him who saved her. She wanted everyone to acknowledge his abilities but due to his age and unassuming nature, no one believed her. At some point in time, during her childhood, Claire began to refer her father as "Baldy" after hearing her mother saying it.

At the age of 6, Claire was trained as a Knight to continue on the family name and surpassed her brother in performance and academics 2 years later. Unbeknownst to her and family, he hid his true powers and pretended to be weak in order to train in secret and fulfil his dream of becoming an "Eminence of Shadow". However dispite Cid's unassuming nature, because Claire deeply loved and cared for her younger brother, she always trained with him and was very stirct towards him as she wanted the best for him.

Around the age of 8, she won a youth tournament. One day at home, she dragged Cid into a nearby forest for special training as a way to toughen him up while avoiding their mother's detection. After she concluded their training, the two Kagenō siblings encountered the Scarface Gang. Wanting to protect her brother, she begged him to flee while she fought off dozens Scarface members. However, much to her horror; she saw him come to her defense and was apparently killed. Before losing consciousness from fighting off the gang, she saw Cid stood up. She later woke up to find her brother unharmed and over joyfully hugged him to see that he was safe but realized that members gang they fought were missing. She was told that a band of hunters chase them away but however, she did not realize that it was Cid that killed all the Scarface members.

At age 12, Claire often trained with Cid outside their manor. She was ultimately disappointed by his performance and berated him for it before she decided to punish him. Despite his sandbagging, she still sought to practice with him whenever possible as she refined her skills better than with anyone else and hoped to teach him to be better.

Claire learned that she began to display symptoms of Demon Possession when she turned 14 and dreaded that she may not live long. Since then, she dedicated much of her time with Cid and prepared him for the future. Unbeknownst to her, he secretly cured her while doing "stretches", and continued to watch out for him.

Kidnapping & Rescue
When Claire became 15, she was set to leave to the capital of Midgar Kingdom and attend their Academy. The night before her departure, the Cult of Diablos infiltrated her family home and kidnapped her with the purpose of using her for their experiments.

Claire was held inside a dungeon where she learned that her kidnapper was Viscount Grease. Claire mocked Grease when she recognized Viscount for his depressing defeat against First Princess Iris Midgar in the first round of the Bushin Festival. Feeling humiliated, he tries to scare her by aiming his kick at the stone wall next to the Kagenō heiress' head who was unexpectedly able to dodge it. Grease compliments Claire on being able to move despite being restrained by Magic Sealing Chains, to which she replies that being taught is important for how to use magic which make Grease comments that her father taught her well how to learn her magic, but Claire explains that she learned everything from her brother.

After delivering some cruel comments about him, Grease inquired if she had suffered Demonic Possession, to which she vaguely confirmed and accidentally brought up Cid during their conversation, causing Viscount Grease to decide to bring him in as well for questioning. Enraged at this admission, Claire broke free of her chains and attacked the Viscount, only to have him knock her unconsciousness.

Unbeknownst to her, she was rescued by Cid and his Shadow Garden, and she returned home safely by her own power. She would return home and she took a day to recover from her injuries, after recovering and a week of investions. And during that time she would pester Cid, she would later leave for the Midgar Academy.

1st and 2nd Year at the Academy
Ever since attending the Midgar Royal Spellsword Academy, she became an honor student due to her high grades and was allowed to live in the dormitory near the Academy. Claire would become the 2nd powerful swordsman behind Iris Midgar and Rose Oriana. During Claire's time at the Academy, she befriended Nina and apparently their friendship became very close with Nina having often helped Claire whenever she could when she needed something. However, Claire doesn't know that Nina is Zeta's personal subordinate assigned to enter the Academy and keep Claire safe under her surveillance. Overtime Claire would continue to amazing all of her peers and getting notice for her talents, even getting the attention of the Knight Order.

3rd Year at the Academy
When Cid became 15 and began to attend the academy, Claire was often annoyed of her peers of how they saw her and Cid as a "mismatched pair of siblings" and at unknown point Claire would introduce her friend Nina to her brother.

Novel/Manga
Claire hurriedly confronted Iris Midgar after learning that her brother was suspected of kidnapping Iris's sister, Alexia Midgar. She knew that whether or not Cid was a suspect, this would ultimately lead to his execution, and tried vouching that her brother was innocent. This did not move Iris, causing Claire to nearly assault her but was dragged out by Zenon Griffey before that could happen.

Anime
After hearing that her brother was a suspect for the kidnapping of Alexia, although she was told to stay in her dorm wanting to save her brother she left her dorm room wanting to speak with the knights and explain that her brother couldn't have kidnapped anyone. However she was stopped by the other students trying to stop her, Claire had also knocked out two of the students that were trying to stop her. When Rose tried stopped her, and Claire had assaulted her and later was subdue by her. Claire would also dislocate Rose's shoulder still trying to go save Cid but was stopped by the others students. After hearing the knights had cause harm to her brother, Claire wanted to give the knights what they deserved for hurting him but was stopped by Rose and the other students would force Claire back to her dorm.

Midgar Academy Terrorist Attack
During the tournament to select qualifying students for the upcoming Bushin Festival, Claire entered the Tournament to become the school's representative but she was defeated by Rose in the finals. After the tournament, Claire was not present during the attack on the academy as her and the other 3rd years were away for a study trip.

Sanctuary Infiltration
In the anime, Claire would stop by at Cid's dorm to search for him to go back home for summer vacation with him, which is earlier due to half of the academy being destroyed. But, Claire was unable to find him due to him hiding above her on the ceiling and had left to go home alone for summer vacation.

Bushin Festival Tournament
When the Bushin Festival began, Claire became her school's representative after the previous representative, Rose Oriana, became a fugitive and was disqualified. Claire went to Cid's room to invite him to see her matches, but much to her anger, he was gone. She eventually found her brother, in the manga she barged into his dorm room by breaking through his window and throttled him for making her wait at his dorm, and while she was strangling him, she was able to guess that Cid was thinking of going to sleep while she strangles him, before she explained to Cid and offered him a ticket to a special seating at the tournament.

On the semifinal tournament, Claire's match has started and she wins the fight hoping Cid will watch her match. In the anime, during Iris's match against Mundane Mann, she went to the VIP lounge to find Cid but only to find him missing. Causing her to leave the stadium go search for him in the city. While searching for him she was unware of his battle as Shadow against Iris and Beatrix all over the capital.

At the tournament's climax, despite the several incidents that had occurred, Claire ultimately won the victory of the Bushin tournament by default.

Red Moon Incident
After winning the Bushin Festival, Claire was treated to dinner at Mitsugoshi Co's restaurants by Cid, where she expressed disappointment at Cid for falling behind his studies and not thinking enough about his future. So Claire proposed to her brother that she was going to take him to Lawless City to take part in the assault during the Red Moon event in hope to gain some credit and secure a better position for him.

Once they arrived, Claire left Cid alone while she attended a meeting between swordsmen at the Magic Swordsmen Association to form a plan to subjugate the Red Tower, and discovered that her brother was missing upon her return. She headed out to Outlaw City to search for him and encountered the Vampire Hunter, Mary, who informed Claire that her brother might have been taken to Red Tower to be sacrificed. Because their goals aligned, the two agreed to work together to stop the vampire queen's revival.

Using a tunnel to bypass the Vampires and Ghouls, Claire and Mary met Beta from Shadow Garden, who were there to get a sample of the progenitor's blood due to similarities with Demon Possession. Claire asked Beta if there was a way to cure Demon Possession for which Beta did not clarify but informed the former not to worry about it, much to Claire's confusion. The two then encountered Juggernaut who decided to kill them and nearly overwhelmed them until Mary was forced to reveal her secret to Claire, becoming a full-fledged Vampire to defeat their enemy.

But, Juggernaut was defeated by Shadow as he launches a fast casual upward kick, which the blow sends him flying until he smashes through the wall that leads outside of the tower and cursing Shadow. Claire saw Shadow, but she feels like she knows him but she never met him until Shadow left. When Mary asked about her situation, Claire replied that she was fine and wanted to give an explanation about who she really was and Mary revealed to Claire that she was a Vampire then told her past as a follower of the Blood Queen. After telling her story, Claire doesn't care about her true origins and decides to save her brother together.

Eventually, the two finally reached the tower where Claire was relieved her brother wasn't the sacrifice and that Elisabeth was finally resurrected. Claire was impaled before the Vampire Queen grabbed her and sucked her blood, allowing Elisabeth to regain full power. Thankfully, Claire was saved by the spirit of Aurora, who temporarily took over her body and unlocked her full abilities to combat Elisabeth. This fight held the Vampire Queen long enough for Shadow to finish it.

After the battle, Claire reunited with Cid to leave the Lawless City. After bidding farewell to their vampire friends, Claire hugged and apologized to Cid for bringing him into the city and nearly jeopardizing his life. She would also reveal to him about her powers through her arm though he was unaware that she became Aurora's host.

Oriana's "Black Rose" Civil War Wedding Incident/Return to Earth
After her ordeal within the Lawless City, Claire became occupied with researching the new powers she obtained through learning more about the Witch of Calamity and wanted to find out about Shadow.

During Winter Break, Cid was on journey trip at the kingdom of Oriana and later to Japan. While he was traversing between worlds, Claire went looking for him and had asked Skel and Po about his whereabouts to which they didn't know. Claire had pulled out her sword at Skel when he asked her out. While looking for him, she had her friend Nina help her to look for him and was ultimately unable to. Claire went back home during winter break upset that her brother broke another promise. She would eventually get a collar to use for her to use to drag her brother home for spring break.

The Academy Disappearances
As the Cult began abducting students, Claire was among those taken and readied for an experiment to merge with Diablos' right arm. After Zeta and Victoria defeated Jean, Claire was already Aurora's host as the former alongside her sub-faction of Shadow Garden planned to continue the experiment under their personal agenda.

After Jean's death came to Claire's reappearance. She began to notice ghosts roaming the Academy and was forced to fight them off until during an exam, she unexpectedly barged into Cid's class to trample his teacher. This was during a monologue with Aurora and as she came to her senses, she was embarrassed and left to be reprimanded by the head teacher. The monologue continued until Alexia came to her about the disappearances. Initially contemptuous towards her for her fake relationship with her brother, the two formed an uneasy alliance when she revealed her connection with Aurora. Their alliance was formed because of Alexia's entrapment with the Crimson Order and the Claire's instances with the Cult. Due to this, their alignment intertwined as they started to conduct their own investigation with their first hint being a forbidden book from the library tipped by Nina.

Next day, Claire finds Cid at the school and puts a collar on him and she drags him to her dorm where she strangles him. Claire is still mad at Cid for breaking his promise. On the night, Claire and Alexia decide to infiltrate the library. At the Library, they were able to translate the book before being ambushed by the head librarian. In the ambush, the head librarian revealed himself as a agent for the Cult. Before they realized it, they were being incapacitated by drugs set up by the agent as he revealed stories of Fenrir and his existence. Before he proceeded to finish the two off, Shadow appeared and defeated the head librarian. In his dying moments,, the librarian revealed that he was a Bushin Festival champion and a Knight who sought justice until he found the evidence regarding the corruption of the Holy Church without knowledge of the Cult's existence and investigated. The investigation went horribly wrong as his subordinates were massacred and his arms was cut off by Fenrir while finding out that his wife became a hostage. In exchange for his wife's safety, he forewent his identity to join the Cult and warned the princess that she'll end up as him.

After the princess stated her resolve to protect her kingdom, the Head Librarian revealed the Cult's true objective is to gain more power as he elaborated the truth regarding the Three Heroes, Demon Possession and Diablos Cells. The Head Librarian never took the cells believing it'll bring shame as a swordsman but stated it's potential that if the Cult can bring Diablos back to life and successfully develop the perfect drugs without any side effects, the Cult of Diablos will have extraordinary power that even surpass the heroes.

The Head Librarian also revealed that the quantity of Diablos' Tears had been dwindling and he doesn't know the cause of it. Because the eternal life from the Tears will soon disappear if the number continues to decrease, even the Cult's leadership will not tolerate it as they want to revive the demon so they can harvest the "Tears of Diablos" again in large quantities. With the perfect eternal life in mind, their leaders could rule over the world and run it with their hands from the shadows. However, if that Tears disappear, they will lose their eternal life and rule over the world by extension.

The Head Librarian stated that it was no coincidence that Shadow Garden appeared in this era as they'll bring the end of the Cult's long reign and warned Alexia to be careful as the organization are the strongest people in the world. In his dying breath, he questioned if they even really are on the side of justice to protect the peace of the world or they want to take everything on the eternal life and the world from the Cult after their fall. As the Head Librarian breathed with pain, he entrusted the kingdom's future to Alexia before passing as she collected his memento and the incident as evidence.

The following day passed with Claire running into Cid and the two talked about what had happen in a reserved room. She confided to him that the Knight Order has been trying to bury the truth about the head librarian and that someone needed to investigate it. Although she asserted that she'll investigate it, Cid knew that he was the person who'll investigate as she hugged him assuring that she'll protect the Academy, Midgar, and him.

Alexia later ran into Claire and continued their investigation before noticing white hazes were suddenly enveloping the Academy. The two hurried to the Academy to the auditorium to see ghosts attack the students before realizing they're both strained with an magic collar that'll denote when their magic reaches 0. After fending off the ghostly horde, the two ran into Nina and Isaac for a briefing of the situation. Isaac accused Shadow Garden of orchestrating the event when Claire grieved on how things escalated quickly to which Alexia retorted Isaac's accusation that there is little to no evidence to accuse the organization of their involvement.

Anxious for a way out, an unassuming student named Suzuki suggested an idea that the students low on magic will stay in the auditorium as defense while the rest investigate. Claire and the group traced the collar source and noticed that ghost encounters have become sparse. She asked his relative who Suzuki was to which she was unsure and Isaac was suspicious of him. They traced the collars to a church and investigated for clues to find a dungeon. However by the time they realize it was a trap, the group fell unconscious one by one with Alexia finding out that Isaac was the insider for the Cult before collapsing.

Upon reawakening, Alexia and Claire found themselves restrained and saw what has happen to the missing students. They were the students the Crimson Order were investigating and the two realized it was too late for them as too much of their blood and magic were harvested to revive Diablos. They decided to escape to avoid their fate when Fenrir revealed himself. The Round Knight was confident that he'll get away with the incident when Claire heckled him but the princess retorted that Shadow Garden will punish him. Aurora decided to intervene and free the two when the Round Knight proceeded to extract blood from Claire's neck. Freed from their confines, the two confronted the martial maniac but were overwhelmed until Suzuki entered the fray. This was after the two legends recognized each other when they were on deadlock.

When the unassuming student revealed himself to be Shadow, he left to leave the scene after his victory against the Round Knight after cutting off the party's collar without a trace. Barely stable, Claire saw Nina regrouping with the team before she knocked them out. Nina then proceeded to force Diablos' arms onto Claire under Zeta's orders and this resulted in her entering a comatose state.
