Alexia Midgar/Chronology

Background
Prior to the events of the series, Alexia grew up with her older sister and spent entire afternoons training together though she would always lose to her. As a result, Alexia devoted herself to becoming stronger in the hopes of surpassing her. With the passage of the following years, their relationship became very distant and strained due to her job as the first princess and leader of the Royal Knights.

She was later arranged to marry a former prodigy and sword instructor named Zenon Griffey at one point. Despite having a highly prestigious reputation, Alexia was wary of her betrothed due to his perfect image and that he was seemingly flawless.

The Kidnapping of Alexia Midgar
She found herself receiving unwanted advances from Zenon Griffey, her arranged betrothed. This prompted her suspicion on him and decided to find a way to get rid of him. Alexia decided it was best to form a relationship with a person of a lower status to anger him, so she rejected a fellow high noble and accept Cid Kagenō as her boyfriend when he "confessed" to her. As a result, the school was surprised by the relationship but Zenon saw through. Cid eventually found out as Alexia revealed her knowledge of the bet that his friends arranged after talking to them. She casually insults Cid and manages to bribe him with gold coins to get him to comply. Despite being abusive to vent her frustrations initially, Alexia started to open up to him by confiding him of her problem and becoming the second person to ever compliment her swordsmanship.

She was later kidnapped by Zenon's men and was sent to a laboratory for her blood to be harvested. She managed to escape with the help from Millia but was stopped by Zenon, who revealed his true colors to her. Enraged, the princess confronted the Knight but to almost no avail when she was overpowered. Alexia was almost recaptured until Shadow came to her aid and overwhelmed him into using the red pills. Mutated, the Knight attempted to overpower the mysterious figure but backfired when he used his "I Am Atomic" to annihilate him alongside his hideout. After being rescued, Alexia was reunited with her concerned sister who she shared a hug with. She also became determined to learn more about Shadow as she came to realize her swordsmanship after witnessing him in action.

Afterwards, she met Cid and remarked her freedom from her betrothal while showing she has genuinely fallen for Cid by thanking him for complimenting her swordsmanship. Believing that his job was done, he tried to leave but Alexia asked Cid to continue their relationship a little longer. Cid outright refused prompting her to become enraged and nearly killing him in response.

Midgar Academy Terrorist Attack
Curious about Shadow Garden and the Cult of Diablos, Alexia decided to take a more active role in the internal affairs of her kingdom by joining Iris' investigation.

Both Princesses along with her two knight from the Crimson Order, Glen and Marco Granger went to the Midgar Academy to meet Sherry Barnett and presented an artifact they found from Zenon's hideout. They were unable to decipher it and asked for Sherry, who is the most brilliant mind in the kingdom, if she can decipher it. The Academy Assistant Principal Lutheran Barnett encouraged her to do the job by stating its a rare opportunity to which she accept. Alexia asked for her sister to help in the investigation regarding the recent massacre on citizens and Shadow which she accepts.

During a night patrol, she encountered three imposters who are disguising themselves as members of Shadow Garden. She was nearly killed when Shadow saved her. Alexia warned Shadow to not become an enemy of her kingdom, which is met with cold indifference. After the encounter, Alexia was put on lockdown by her sister.

The next day, Alexia was approached by Sherry as she wanted to confirm her relationship with Cid Kagenō. She clarified to the researcher that they pretended to be a couple for personal reasons and that they never dated in the first place. Happy that she's not interfering in a relationship, Sherry was ecstatic to work even harder to decipher the artifact and left shortly before Alexia seethed into taking her anger out on her tea cup.

Sanctuary Infiltration
Alexia made preparations by visiting Mitsugoshi with Iris for her departure at Lindwurm as a special guest of the "Goddess's Trial" event, in order investigate the Archbishop Drake regarding dark rumors of corruption and missing orphans. Peeved by the time to get there, she went to soak her self at a hot spring. While there, she saw Cid arrive and was surprised by his nudity though he didn't ogle her. They casually talked about their arrival and she apologized for the spiteful response to his rejection. Alexia told him of the event and that she will be attending as special guests. Cid thought she would participate as she clarified that she is unable to due to important matters and offered him into the Crimson Order for her reiteration of her withdrawal. Despite her insistence, Cid bluntly refused as the conversation ended when he left while retorting her fixation on his "Excalibur".

Hearing the news of Drake's death, Alexia went to the church and had an audit with acting archbishop Jack Nelson and explained that she was there to investigate his death. Nelson dismissed the jurisdiction she was given as he had told her off that the Church will be handling the investigation and that she will need to be reapproved to conduct an investigation on the issue as he had already send the letter to the king Klaus Midgar while lastly telling her to enjoy the "Goddess's Trial" event. Seeing through that they were destroying evidence and obstructing an thorough investigation, Alexia seethed that she was unable to do anything regarding the deceased Archbishop.

At the trial, Alexia sat in the VIP seat along with Rose Oriana who sat next to her as she silently angrily looked at Nelson who was making a speech without sorrow with a spiteful look. However, what annoyed Alexia the most was the person next to her, Natsume Kafka because she felt she was the type of person who hid her personality just like her. When Cid was called up for the challenge, Alexia alongside the three were shocked to see that what appears is not Cid, but Shadow who summons the ancient warrior Aurora and challenges her. Nor do the princesses find out who the ancient warrior is until Natsume tells them about the Witch in elaborate detail to Alexia's peeve on the writer's approach by teasing Nelson to divulge information. Although Nelson and many of the spectators believed that the Witch would win, Alexia disagreed to Natsume's delight when she was able to analyze the closing distance and positions of the two combatants.

Upon Shadow's victory, chaos ensued as the Paladin Knights attempt to capture him, the Door of Beckoning appearing, and lastly members of Shadow Garden appearing. She and Rose went to the gateway alongside members of Alpha's squad with the captured Nelson to find themselves in the Sanctuary. The two would then come to learn the connection with the recent events with the two organizations and the truth about the Three Heroes, Demon Possession, as well as the Cult of Diablos's origins and true objective until Alpha revealing Nelson's true affiliation as the 11th Seat of the "Knights of Rounds", to which he confirms it by revealing himself as Nelson the Avaricious and tends to separating them into groups.

Alexia saw the fight between Alpha and Delta against Nelson and his deluge of copies in the Sanctuary defense system as she was stunned to see Delta brutality by fighting like a berserker with no technique. When the defense system breaks as Nelson is surprised that over hundred of his copies have been defeated without even breaking a sweat. Alpha states that even if he was able to create a hundred copies, they all still have one brain and he couldn't control them all that well. Nelson then sees a statue of Olivier and calls for Olivier to come. Olivier comes out, but at the same time Epsilon's team joins Alpha and states they are done with the investigation and can leave. Nelson is surprised that they are running away, but Alpha explains their objective is to cut off the source of power and now know how the Sanctuary defenses work, so they will be returning again.

Alexia then decide to escape from the Sanctuary along with Rose and Natsume until outside, the three saw Shadow's magic annihilate the Sanctuary and flood Lindwurm. Concluding they were ignorant to the true battle even have learned the connection with the recent events with the two organizations, Alexia alongside Rose and Natsume made an alliance in hopes of protecting what's most dear to them (Cid), which they swore friendship by gathering and sharing information to learn what they could.

Bushin Festival Tournament
Alexia heard the news about Rose going into hiding after stabbing her fiancé Perv Asshat and tried to investigate the incident with Natsume Kafka when she gave her information she didn't had access to. The two thought that if Rose was caught, she would be in serious trouble but confident that she would not receive the death penalty due to her royal status. Alexia wanted to confirm Rose's predicament by finding her before the Oriana Kingdom does, in hopes of getting her side of the story much to Natsume's protest. Despite being irritated by her words, Alexia understood her reasonable advice and decided to consult her older sister. Natsume later gathered more information about Rose and the Chancellor as she heard unsavory rumors about him. In the anime after Alexia left, she was given more info about Perv by Beta without her knowing. This was done to keep her busy and avoid get into trouble.

While investigating, Natsume provided Rose's whereabouts to Alexia and went to Midgar's tunnel systems to track her. Natsume then shared information to Alexia about the Chancellor to confirm their suspicions of him by recalling the incident that Rose instigated when he was attacked by her without any injury. They believed he was possibly connected with the Cult of Diablos after recalling the incident. Natsume noted that it will be difficult to provide evidence of his involvement with the Cult as the situation is a matter of national and religious prominence which meant that normal evidence will not suffice. Alexia added that her father told her that they needed something to convince the masses and neighboring countries if they wanted to link the Cult's relationship with the Holy Church of Divine Teachings and thought that some of their top brass were involved with the Cult. Even Natsume stated that if they continued to deny the Church, they would be considered as heretics.

Alexia was irritated by her father's inaction due to his long-standing policy of not showing any antagonism with the Church and told Natsume that Iris told her that King Raphael Oriana didn't seem to be affected by Rose's actions which caused suspicion when Iris had said that the King seemed to have been somewhat hollow. Alexia intended to meet him and she slightly smelled the sweet scent from the King's body. Hearing the King's irregularity, Natsume noticed and told Alexia they are too late. Alexia was also sure that the Cult is definitely make their move and if they continue to do nothing as her father suggests, the Cult will end up causing a lot of trouble for the kingdom.

During their search for Rose, the two suddenly felt a burst of magic and ran towards it to find her. Upon finding her, the two witnessed her bloodied with dozens of assailants corpses. Alexia demanded Rose what happen and her side of the incident as she tried to beat her into answering. This backfired as Rose incapacitated her with ease and left the tunnel system to confront her father and fiancé.

In the anime, Alexia went to meet Natsume but already left a document which contained information that Alexia needed there. Alexia was practicing her sword play when Shadow was about to release his "I Am Atomic", but ignored it to continue her practice.

Great Trading Company Conflict
Sometime after the Bushin festival and Red Moon incident, Alexia came to check up on a pondering Cid and the two sparred. The two noticed improvement in Alexia's swordsmanship but she dwelled in her defeat against Rose and sought to continue improving. The two parted ways as Cid started his collaboration with Yukime as "John Smith".

The Academy Disappearances
After the Academy's Winter break, Alexia investigated the disappearance of Claire to find Cid's collar. There she discovered ancient texts on the collar and questioned Cid about it. Later in the night in the aftermath of Delta and Zeta's fight, Alexia found Shadow and misunderstood the situation as she was almost ready to apprehend him before he knocked the knights unconscious and fled the scene.

Sometime after Claire's reappearance, Alexia talked to Claire much to her protest for her fake relationship with her brother. The two discussed that Cult of Diablos infiltrated the Academy and Knights with Diablos' right arm being revealed to be sealed in the Academy. The two formed an uneasy alliance to further investigate into the matter with their first hint being a book from the Forbidden Library. Alexia along with Claire then went to meet Claire's friend, Nina because she heard a story that she helped Cid to get forbidden books from 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. Alexia started to feel strange and became incapacitated when the head librarian told them the stories of Fenrir and confirmed his existence after Alexia concluded that Fenrir is a Cult member. Before he went to incapacitate Alexia and Claire after taking the effect of the drugs scent, Shadow then appeared to defeat the head librarian and in his last moments, the dying librarian revealed that he was a Bushin Festival champion and 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 told Alexia that he was powerless to rebel against the Cult while warning the princess that she'll walk the same path as him.

After Alexia stated her resolve to protect her kingdom as a princess, the Head Librarian revealed the Cult's true objective is to gain more power as he revealed to truth about the Three Heroes, Demon Possession and Diablos Cells are only suitable for woman through using the red pills that Zenon used, which he called him a poor student. The Head Librarian never took them believing it's a shame for a swordsman, but stated the potential of them that if the Cult can bring the Demon 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 for the Tears of Diablos have been dwindling and that he doesn't know what 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 the their fall. As the Head Librarian breathed with pain, he entrusted the kingdom's future to Alexia before passing.

Alexia collected the testimony and book as evidence and tried to use them to convince her sister of their involvement. To her dismay, Iris became a puppet for the cult as she was being manipulated by Hubb into believing that the cult doesn't exist and it was a fabrication done by Shadow Garden. Hubb provided fabricated evidence of an insider's document with Alexia refuting them as she tried to reach out her sister. However, her plea was rebuked by her sister as she threaten her with no mercy if she were to obstruct her in the matter before leaving.

Trapped that the Knights and her sister couldn't be trusted, Alexia 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. A relative of his named Christina tried to interrupt him before he could finish out of fear to save face to which in response Alexia stopped her and allowed him to finish. He would finish his suggestion that the magic being absorbed is traceable and that the investigation will have to cut through the ghost surroundings. Isaac protested that he's an unremarkable and inferior student who should not be trustworthy. Suzuki sneered at Isaac before the rest of the group agreed to his plan except Christina. It did not took long to convince her otherwise as Suzuki was willing to be left behind if he were to slow down the group. On their way around campus, the group ran into some of the students who fled the auditorium. One of them was Eliza. Alexia noticed an abnormal amount of magic on her collar but was too exhausted to question her when they were ambushed.

During the ambush, one of the students was fighting a losing battle when Suzuki asked Eliza whether she was going to fight or not. Eliza's entourage tried to sneer him away from further questioning as he lamented that the student in question was going to die with her magic running to 0. Suzuki decided to take action by dissipating the ghost and save the student. He explained that magic can be transferred to the collars and by extension, it can postpone its denotation. Alexia was impressed by his deduction as he went onto accuse Eliza of extorting other students magic. Eliza admitted to the crime as she thought to have leverage over the party due to her high noble status till Suzuki restrained her. He clarified to everyone including Eliza of the situation she's in that no one will testify if he were to kill her because by the time it'll be discovered, no one would live to testify and not even her status can save her. In the end, Eliza was forced to share her ill earned magic to those running low and return to the auditorium with Alexia handing out her punishment later.

Alexia and the group traced the collar source and noticed that ghost encounters have become sparse. She asked Christina who Suzuki was to which even 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 witnessed what has happen to the missing students. The students in question were the ones 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 Diablo. 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.

Alexia was astonished to see Suzuki keeping up with Fenrir's Blood Fang with a fountain pen but was horrified when the unassuming student revealed himself to be Shadow. As Shadow proceeded to leave the scene after his victory against the Round Knight, Alexia called out to him to know what he's fighting for to which he reiterated to her not to get involved. Dissatisfied with his answer, she pleaded to him to ask what is he going to do with the world. Before realizing, Shadow laughed as he cut off the party's collar and vanished from the scene without a trace.

Alexia came call Cid to the schoolyard the following day to inform him that he is involved in his sister's condition and that the Knights want to hear about it. Despite having an alibi, Alexia clarified that the Knights insistence is a formality and they don't expect anything out of him. She expressed envy towards him that he is very peaceful despite what's going on and asked if he wanted eternal life. She would regret asking him as he gave an answer that disappointed her such as "I would destroy the world if I could have it" before being called for questioning. Alexia concluded that Shadow isn't arrogant as Cid and if he wanted eternal life, then the world's fate is ambiguous (Volume ended on a cliffhanger).
