-BA-Arius Squad Halloween!

General Information Arius Squad's five members were an elite team formed by Beatrice yet only seen by her as mere pawns ready to be disposed of at any time. They were the team placed in command for the assassination attempt on Seia and the attack during the events of the Eden Treaty Signing. It was also during this time period that Azusa, who was originally assigned as a spy infiltrating Trinity, instead defected and betrayed the Squad after realizing that there was more to life than pointless suffering, leaving a high-intensity conflict between Azusa and Arius' team and infuriating Saori. After their failed attempt in conquering both Gehenna and Trinity, Beatrice deemed them useless and decided to retrieve Atsuko back and initiate the ceremony to sacrifice her while leaving the other three members to perish, accidentally leading them to Sensei's hands.

The Arius Squad lives in exile, unable to return to Arius' campus or enroll with Trinity or any other academy due to their actions.

Due to Beatrice's teachings, all Arius Squad members are nihilistic. All members except Atsuko came from impoverished backgrounds.

Arius Branch School General Information Arius is a school that had broken off from Trinity General School. No one knows where their autonomous district is, except a few individuals such as Joumae Saori. The students of Arius primarily learn to fight and kill, rather than regular subjects that normal students would learn, making them a terrorist organization.

Their motto is "Vanitas vanitatum, et omnia vanitas." (Vanity of vanities and all is vanity.), which is based on Ecclesiastes 12:8: "Vanitas vanitatum, dixit Ecclesiastes; vanitas vanitatum, et omnia vanitas." (Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity.). Their logo is a skull with a crown and a rose, which are common elements of a vanitas artwork.

In the aftermath of the district's fall, Trinity has assumed de facto control and is working to integrate as many students into its system as possible. While Saori continued to operate independently, Nagisa was eventually able to arrange a meeting with Atsuko to begin rapprochement and lay the disagreements to rest. The Arius students invited to begin integrating into Trinity, however, are undergoing a long and arduous rehabilitation process through both the school and SCHALE. Many are unused to having access to clean, cold drinking water or items such as tablet computers and struggle to cope. The Sisterhood also carried out their own investigation into the district, eventually finding key artifacts left behind by the old Justina Council of Saints which had somehow survived both the ravages of time and Beatrice's rule.

While many students have left the school to enroll at Trinity, many would also stay at the derelict school they consider their home. And eventually force the hand and return of the Squad itself.

Introduction and Personality Saori - An unparalleled expert in guerilla tactics. Saori shows the personalities a leader would normally have: fierce, strategic, and responsible. Saori may often come off as stoic, overly serious, and unsociable, but once she shows her emotions, she does not hold back. However, given her status as a survivor of Arius' abuses and cult-like behavior, Saori is often naive and knows little about matters that are trivial to most students Atsuko - She's silent and always communicates through sign language, but perhaps there's more to this than meets the eye. Her squadmates call her "princess," and Saori in particular seems very protective of her. But she has a kind heart. Compared to the rest of the Arius Squad and possibly all of Arius, Atsuko appears to be the kindest, having a personality that can be considered quite exceptional in Arius. Hiyori - She is a cowardly student that gives off a gloomy impression. She appears to have a fear of pain and suffering, whether it be upon herself or even others. With her low self esteem and fundamentally negative vibe, self-deprecating words often find themselves coming out of her mouth. A petulant and melancholic member of the Arius Squad. She has low self-esteem, usually sees things in a negative light and is often self-deprecating when it comes to herself whether it's over the Squad's dire finances, or not getting to read her favorite magazines. She even cries and laments over her belly-button looking different from others. Misaki - One of the four members of Arius Branch School's elite Arius Squad. Misaki is a girl that gives off the impression of being an unsociable girl with little words. She shows little interest in both others and herself, and her wrist and neck are layered thickly with bandages, as if attempting to hide something. Compared to the other Arius Squad members, Misaki's actions resemble the Squad's beliefs the most. Although the Squad believes that everything is in vain, their actions seem to contradict that. Misaki, however, suffers from severe depression between her frail body and the abuse she suffered during her time in Arius. Because of this, she has repeatedly cut herself and outright attempted suicide on multiple occasions, only being stopped by Saori and later Sensei. Her depression has eased by the time of Sheside Outside, though she remains distant and reserved.
