Arius

Arius Branch School is a unique faction in Blue Archive, having broken off from Trinity General School due to ideological differences. Its location is unknown to most, with only a few students aware of its whereabouts. Students at Arius Branch School are primarily trained in combat and killing rather than regular academic subjects, leading to their reputation as a terrorist organization. Their motto, "Vanity of vanities and all is vanity," reflects their nihilistic worldview. Arius Branch School is ruled by Beatrice, who controls students through inhumane means, and uses her powers to hide the school's entrance. The school has been involved in major incidents such as sabotaging the Eden Treaty signing and possesses dangerous weaponry like cruise missiles and halo-destroying bombs. The Arius Squad is the elite unit of this school, once attempted to overthrow Trinity and Gehenna, but ultimately failed and were abandoned. Arius Branch School plays a complex and significant role in the game's storyline, with its history and motivations gradually revealed as the story progresses.
