Sisterhood

The Sisterhood is a major faction within Trinity General School in Blue Archive, with influence comparable to the Tea Party and the Knight Hospitaller. They ostensibly aim for the happiness and well-being of everyone in Kivotos, but many Trinity students are suspicious of them. As successors to the infamous Justina Council of Saints, the Sisterhood holds many secrets, some of which may shed light on Trinity's unknown history. Their headquarters is the Trinity Cathedral, and members often appear as nuns. The Sisterhood has a powerful intelligence network and once followed a non-interventionist policy, but in the story, they abandon this policy and actively participate in events. Members of the Sisterhood include characters like Wakaba Hinata and Utazumi Sakurako. Hinata is responsible for the management of the cathedral and items, while Sakurako is a member of the idol group 'Antique Seraphim' and aims to dispel prejudice against the Sisterhood. The Sisterhood has also assisted members of the Supplementary Lesson Department and Sensei against Mika and participated as witnesses in the signing of the Treaty of Eden.
