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.

Within the Sanctuary, Alpha explains to the princesses about the truth behind the Three Heroes and Demon Possession, from which the Cult wanted to maintain under their control as she revealed her lineage with the Hero Olivier. Alpha and Shadow Garden even suspect that the Cult's goal isn't just reviving the demon, thus they proceed to see for themselves by exploring Hero Olivier's memories.

Seeing Olivier's memories, Alpha and her entourage have seen the truth about the history of the Three Heroes and Demon Possession, as well as the Cult of Diablos' origins and true purpose was to create Tears of Diablos. Alpha then confirms every guess she passed on to Nelson until he reveals his true affiliation as he intends to fight back by separating Alpha from Epsilon's team inside the Sanctuary's defense system. 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 the situation to Alpha and reported that everything within the Sanctuary had been obliterated, with Alpha noting that it was the simplest and most effective solution. Also, Epsilon conveys that Beta has been working with Princesses Alexia Midgar and Rose Oriana to learn more about the Cult of Diablos, using her "Natsume Kafka" identity to infiltrate their inner circle. Finally, Epsilon announced the results of her team's research, in justifying the hypothesis theory by revealing that Aurora as the true identity of Diablos.

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.

Victoria also later reports to Alpha that Zeta had joined Shadow at the Academy after returning from her mission, without reporting to her.

Alpha confronted Beta after she along with 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.
