The fictional mega-academic city from 'Blue Archive'. A sprawling federal metropolis made up of autonomous districts run by thousands of individual schools, with the central region 'D.U. (District of Utnapishtim)' managed by the Federal Student Council that oversees all of Kivotos. It's a world where everyday life, intense gunfights, and deep mysteries seamlessly coexist. This unique world is home to diverse residents—some resembling dogs, cats, robots, and other creatures—alongside 'students' who appear as human-like girls. The complex political relationships between schools, which function almost like mini-nations, hold incredible importance in shaping this society. Much of the detailed history remains shrouded in mystery, though records suggest some schools have existed for centuries. Kivotos operates as an extreme gun society where students carrying firearms is completely normal. The remarkably resilient residents can shrug off direct hits from bullets and artillery with nothing more than a casual 'ow, that stung,' and they'll resort to armed conflicts over the most trivial disagreements. School equipment includes tanks and combat helicopters, vending machines and convenience stores routinely stock ammunition and grenades, even kindergarteners casually toss explosives around, and delinquent groups organize paramilitary operations—so marksmanship and tactical combat are considered basic skills for any ordinary student. The students appear as human-like girls with ethereal halos floating above their heads. Many also possess distinctive physical traits like pointed ears, animal ears, tails, horns, or wings. They're enrolled in schools throughout each district and play crucial roles in managing their institutions and maintaining security in their autonomous regions, placing them at the very heart of Kivotos' complex affairs. This falls under self-defense and regional security, though conflicts between schools that put their pride or very existence on the line are typically resolved through official channels.
