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 has always wanted a little brother. At the age of 2, she got her wish when Cid was born and was ecstatic to see her new baby brother. Around age 3, she got herself into trouble on occasions as Cid once pulled her back when she once almost accidentally 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 to her father as "Baldy" after hearing her mother say 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 the family, he hid his true powers and pretended to be weak to train in secret and fulfill his dream of becoming an "Eminence of Shadow". However, despite Cid's unassuming nature, because Claire deeply loved and cared for her younger brother, she always trained with him and was very strict towards him as she wanted the best for him. This would lead to an overly attachment and a protective nature towards her brother. At some point in time, Cid would tell her about the concept that it's not important how much magic a person has but how well they use it.

Around the age of 8, she won a youth tournament. One day at home, their father told them about the Scarface Gang, but he warned them to not go anywhere near them. She dragged Cid into a nearby forest for special training to locate the Scarface Gang as a way to toughen him up while avoiding their mother's detection. After walking around in the forest for 2 hours. Cid wanted to leave as it was almost noon, and not wanting to anger their mother if they didn't make it back by lunch she concluded their training, the two Kagenō siblings began to turn back but they encountered the Scarface Gang. She would begin to fight against the Scarface members but wanting to protect her brother, she begged him to flee while she fought off dozens of 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 had a flashback back to the time she was three and saw Cid stood up right before she lost consciousness. She later woke up to find her brother unharmed and overjoyfully hugged him to see that he was safe but realized that the members gang they fought were missing. She was told that a band of hunters chased them away but however, but 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 to 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, her mother would arrange a farewell party for her. In the anime, Claire would go train with her brother near a lake where she would beat her brother in training. But she would get the sense of a blade that almost came close to her neck. A maid would tell her that her mother was calling for her and guests were arriving for her farewell party for her departure. Since Claire would be attending the academy she told Cid that she wouldn't be able to practice with him for a while but told him to continue training on his own. In the manga, Claire would wear her uniform and ask her brother how she looked in her uniform. She was set to leave for 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 to use 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, Cid would find her and undo her restraints and when she woke up she would return home safely by her power. She would return home and she took a day to recover from her injuries, after recovering and a week of investions. During that time she would pester Cid, and after healing her wounds she was set to depart but before leaving she would stop to look back at her brother and would leave for the Midgar Academy.

Living Life As An Academy Student
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 in the academy behind 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 as a student and keep Claire safe under her surveillance. Over time Claire would continue to amaze all of her peers and get noticed for her talents, even getting the attention of the Knight Order.

When Cid turned 15 and began to attend the academy, Claire was often annoyed by her peers how they saw Cid as unremarkable, and they saw her and Cid as a "mismatched pair of siblings" At an 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 in 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 save her brother. 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 to stop her, and Claire 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 get revenge on the knights for harming him but was stopped by Rose, as she will also be labeled as a criminal is she'd attacks the knights. Claire would believe that Rose called her brother a criminal, although Roses states that she didn't and forces 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 dorm to invite him to see her matches, but Cid decided to avoid her. While waiting outside, Claire decided that she would wait for Cid. But much to her anger, he wasn't in the dormitory and had already left while Claire waited for her brother. After waiting for so long, Claire began envisioning her beating Cid into a pulp in her mind and getting increasingly angrier as the moment passed.

She eventually meets her brother after waiting so long and, in the manga, Claire barged into his dorm room breaking through the window. While in Cid's dorm, she immediately strangles Cid for making her wait in front of his dorm while being able to guess that Cid was thinking about how it's a pain to deal with her and going to sleep while she strangles him. Claire threatens that if Cid breaks another promise she'll make him pay. Cid promised that he'd do better in keeping his promises, although Claire had removed her hands from Cid's neck she still was sitting on top of him. Claire told Cid of dogs mounting each other to establish dominance to teach them to show them who's boss. She releases him from her grip before Claire explains to Cid that while giving him a ticket to special seating at the tournament she wants him to watch her fight.

She would later stand up, but when Cid shows no knowledge about Claire replacing Rose. Claire glares at Cid revealing that she's replacing Rose to represent the Academy, then proceeds to go back to strangling him and asking him if he remembers her birthday, her previous tournament results, and her first win, which Cid remembers. She would tell him to remember these things and be more attentive toward her if he wants to live a long happy long. After winning her match she would go and wait by her brother's dorm to ask him if he'd had fun watching her match.

In the semifinal tournament, Claire's match has started and she wins the fight hoping Cid will watch her match. In the anime, as Iris' match against Mundane Mann is about to begin, she goes to the VIP lounge to find Cid but only to find him missing. Causing her to leave the stadium to go search for him in the city. While searching for him, Claire was unaware 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, in the anime after the battle between Shadow, Iris, and Beatrix. The matches of the Bushin festival would resume. Claire would defeat Imatry Nottaloos. But due to Mundanne Mann revealing his true identity as Shadow with forced him to be disqualified and Iris withdrew. Claire ultimately won the victory of the Bushin Festival championship by default. After winning the Bushin Festival, Claire gave speeches to parties that requested her, where she met many people she found out about the Dark Knight Association and the mission within the Lawless City's subjugation mission to hunt the Vampire Queen.

Red Moon Incident
After winning the Bushin Festival, Claire pestered Cid to throw her a celebratory dinner, Cid treated her to dinner at Mitsugoshi's restaurants by Cid. At the restaurant, where she had Roast Beef for the first time. In the manga, Claire would find out that Cid wasn't at her matches when he said that she gave her opponent a thumbs up, this would cause her to grab her brother's neck and jump on her brother pinning him to the ground. Claire would reveal that she wasn't giving a thumbs up because she flipped off her opponent while pointing a steak knife at him. Claire would express 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 the hope of gaining some credit and securing a better position for him.

Once they arrived, Claire would keep a hand on Cid to make sure he doesn't get lost. Claire left Cid alone outside of the meeting at an Inn 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 to the Inn and was annoyed that he left the room despite her telling himm to stay in the room. She then heard a scream, and a Man was being attacked in the corridor by a ghoul, Claire effortlessly killed the ghoul then asked the man if he had seen her brother. 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 explain 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. In the manga, Claire would make a big entrance trying to rescue her brother flipping off any vampires. Claire would be dismayed as at first she thought her brother was sacrificed but 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, and back at the Inn they were staying at Cid was going to apologize to Claire for wandering on his own. But when he reached to Claire's room and opens the door he sees the magic circle that Claire has on her hand wrapping it up with a white bandage, while she mutters to herself about her right hand (left in the anime) trembling and a special power had awaken in her. Cid would quietly leave after seeing this. The next day Cid and Claire prepare 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. Cid told her that he would support her, Claire was thankful for his words, she rested her hand on his hand, and rested her head on his shoulder while riding the train to leave the Lawless City.

That Age Already
Sometime after returning to Midgar after leaving the Lawless, Cid wonders if his sister is okay after what happened, he recalls her rambling about her "special power". He then believes that she's going through a chūnibyō phase. Cid had contemplated on whether to give her space, but he didn't want her to sulk over being neglected either. He then decides to check on her. But upon entering his sister's dorm, Claire pleads for Cid not to enter, as she wants him to keep his distance from her. Upon looking at the bandage on her arm, wondered about those bandages. Claire tries to tell Cid about something inside of her that isn't her, but based on a vague sensation, she imagines that if this "something" inside her were to hurt Cid. Cid would believe that Claire was going through something, Cid would tell Claire that he was concerned, but Claire mistook it as her not normal. Claire thought that Cid was acting calm to avoid hurting her.

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, during Cid's journey to the Oriana Kingdom and later to Japan. While he was traversing between worlds, Claire went looking for him and asked Skel and Po about his whereabouts 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 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.

The next day, Claire finds Cid at the school and puts a collar on him and she drags him to her dorm where she pins him to the ground and begins to strangle him. Claire is still mad at Cid for breaking his promise and him lying to her. After talking to Cid about the situation happening with the academy, she tells Cid that he's the best brother while crying, Having imagined the possibility if she where to die. But after comforting words from Cid, she promises to come back alive, she would later give him a very tight hug. 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 an 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 brought the two for sacrificed to releasing the Diablos' right arm, Shadow appeared and defeated the head librarian.

In his dying moments, the head 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 still served them even though his wife had died peacefully without knowing anything because his will to fight had been severed just like his arm while warned the princess that she'll end up as him.

After the princess stated her resolve to protect her kingdom, Claire hears the Head Librarian's revelation regarding the Cult of Diablos' true objective in gaining more power as he elaborated the truth about the Three Heroes, Demon Possession and Diablos Cells are only suitable for women through the use of the red pill, to which the Head Librarian showed the pill which had also been used by his student, Zenon Griffey is the person who wants to scapegoat her brother for Alexia's kidnapping. Although the Head Librarian never used the pill believing it was a disgrace for a swordsman, he stated his knowledge of the red pill's potential that if the Cult can bring Diablos back to life and successfully develop the perfect drugs without any side effects, then the Cult of Diablos will have extraordinary power that even surpass the heroes.

The Head Librarian also revealed that the quantity of Tears of Diablos 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 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' severed right arm onto Claire under Zeta's orders and this resulted in her entering a comatose state.

Volume 6
A month after the incident, Claire remained her her comatose state. But Cid was told by Zeta that she would wake up eventually. Claire remains lying on her bed unconscious in her dorm room with medical equipment, she is watched over by Mu as remains in her current state. However, her absence had caused her to miss the end-of-year exam which threatened to have her repeat a year. In the mist of mid-February, Cid and Nina would visit her in her dorm room to get a report on her progress. Where Mu would give them a report on her condition.
