Alpha/Chronology

Possession & Exile
During her early childhood in the elven country, a young descendant of Olivier lived a relatively normal life, even becoming acquainted with the girl who would later become Beta. Upon discovering that she was afflicted with Demon Possession however, the young elf was exiled and forced to flee from her home. As the Possession progressed through her entire body, her deteriorating condition lead to becoming captive to a group of bandits.

Rise of Shadow Garden
Before she succumbed to her condition, her captors were killed by a passerby who later restored her to normal. Swearing her loyalty as repayment, Cid recruited the girl and was renamed to Alpha. He revealed the true nature of the disease as well as the existence of the culprits behind the conspiracy, the Cult of Diablos. Upon learning the truth, Alpha agreed to join his cause and formally created the initial formation of Shadow Garden.

Afterward, Alpha, being sheltered and guided by Cid, trained to improve her swordsmanship and magic, while also learning different various skills from her master. Eventually, she was reunited with Beta, before being later joined by Gamma and Delta. Together with Beta and Gamma, the three discussed and planned the structure of the organization, using their leader's "Shadow Wisdom". In the meantime, both Shadow and Alpha continued recruiting members, lastly enlisting Epsilon, Zeta, and Eta.

First Assault on the Cult
After Cid's elder sister, Claire, was kidnapped by the Cult of Diablos, Alpha led the investigation to track down their location, although her master quickly ascertained their enemies' position himself. Later, as Shadow Garden assaulted the Cult's hideout, Alpha led the other members in slaughtering the guards before confronting the culprit behind the abduction, Viscount Olba. Although she was easily able to overwhelm him, Olba barely escaped capture after consuming drugs to enhance his strength. Despite the Viscount's getaway, Alpha nevertheless was confident that Shadow would handle him, believing that he had already foreseen their enemies' movement. Subsequently, her faith was soon rewarded, as Cid successfully defeated Olba and liberated his sister from captivity.

Following their success, Alpha and the other girls later requested a meeting with their master, showcasing the results of their research into the Curse and the Cult. In conclusion, the seven determined that they would need to disperse in order to rescue other victims as well as continue investigating their sole enemy. After receiving Shadow's permission, Alpha tearfully departed along with her allies to begin bolstering their resistance.

Princess Alexia's Kidnapping
Alpha later reunited with Cid after learning of his suspected involvement with the abduction Princess Alexia Midgar, particularly her master's relationship with the royal member. After both suspected the Cult of Diablos's involvement in the kidnapping and conspiracy against him, the young elf then departed to gather their forces to counterattack the Cult and rescue the princess.

Later, observing Shadow Garden's operation's progress, Alpha intervened during Princess Iris' battle against the demonized Millia, the experimented daughter of Olba, opting to dispatch the child as mercy before disappearing.

Midgar Academy Terrorist Attack
Absent during the terrorist assault on Midgar Royal Spellsword Academy, Alpha mets with Gamma after the incident. Gamma informed her of the situation. Despite Shadow Garden being framed as the perpetrators by the Cult of Diablos, she nevertheless resolved to continue following her master's will, ordering Gamma to gather the "Seven Shadows" before departing.

Sanctuary Infiltration
After sending a letter to Cid to come to Lindwurm, Alpha meanwhile examined the murder of Archbishop Drake, however, her focus remained on the truth regarding the Hero Olivier and the Sanctuary.

As such, after Shadow defeated the Witch of Calamity Aurora during the Goddess's Trial, Alpha and Shadow Garden seized the opportunity to investigate the Sanctuary, forcibly bringing acting Archbishop Nelson, as well as Princess Alexia and Rose Oriana unexpectedly.

Within the Sanctuary, Alpha revealed her lineage with Olivier and her history with the Cult's goal until Nelson attempted to retaliate. Along with Delta, the two repelled the Knight of Rounds' onslaught before retreating upon the completion of their investigation.

Later, after the destruction of the Sanctuary by their master, Epsilon briefed her of the situation and announced the results of their research, revealing Aurora as the true identity of Diablos.

Bushin Festival Tournament
After Rose escaped from the Bushin Festival, Alpha approached the fugitive princess to offer her the opportunity to join them to rescue the Oriana Kingdom against the Cult of Diablos. Upon Rose's acceptance, Alpha then guided the former student council president to their hidden base, Alexandria, where she entrusted their latest recruit to the instructor Lambda for training before departing.

Great Trading Company Conflict
As the conflict with Mitsugoshi Company's rival, the Great Commerce Alliance, escalated, Alpha and Shadow Garden noticed the increasing circulation of counterfeit banknotes into the economy, which consequently could ruin both companies if left unrestricted. However, their attempts to locate the source of the forgeries had failed due to the interference of a mysterious guard named "John Smith". After dispatching Delta resulted in her presumed death, Alpha then confronted the new adversary, only to discover that Shadow was the true culprit. Demanding an explanation, she attempted to subjugate him to force an answer. However, she was ultimately defeated and left by her master.

Following the confrontation, Alpha became heavily depressed while the counterfeit situation continued to worsen, believing that her master had abandoned Shadow Garden. Fortunately, upon receiving a decrypted message previously given by Shadow earlier detailing his motives, she was exuberant that he had not betrayed them and even supplied them the funds to resolve Mitsugoshi's financial crisis. With her faith reaffirmed, Alpha then departed with Shadow Garden to retrieve their funds which her master had collected in the place where his sister was abduct, after reuniting with Delta.

Subsequently, Shadow Garden was able to locate and collect the stash before infiltrating the Great Commerce Alliance leader, Gettan's residence, discovering a letter addressed to his former fiancé, Yukime, the White Tower Monarch of Lawless City. Later, Alpha approached the fox lady, giving her Gettan's letter before revealing Shadow's connection with the Mitsugoshi Company and his plan to establish their strength. Despite the revelation, the two agreed to form an alliance against the Cult of Diablos and departed together to discuss their plans.

Return to Earth
Alpha immediately rushes over to the Oriana Kingdom after hearing the news that Shadow and Beta are getting sucked inside the Black Rose in order to take charge of the damage control operation by rebuilding the capital and making a decision for Rose Oriana about her own kingdom situation.

Alpha confronted Beta after she and Shadow returned from their adventure in another world. Beta had taken some of the otherworld's technologies back with her as well as one of its inhabitants, from whom they could hopefully learn how to use these items. However, while the girl intended to just pawn her captive off to someone else, Alpha placed the Otherworlder under Beta's own custody, arguing that she needed to take responsibility and fearing what Eta would do if she got her hands on an alien.
