Toyomi Kotori - Cheering you up

Kivotos: Kivotos was made from the union of thousands of academies. The academies are divided into mostly independent districts. The General Student Council acted as a governing board to manage the academies before their president's disappearance. After that, the city became a de facto anarchist society. Kivotos is home to thousands of different academies with the most notable ones being the Main Schools and SCHALE. Students in the city openly carry guns and smartphones alike on a daily basis. The city's technology is highly-advanced, with holographic communications, robots, powered exoskeletons, and mecha being commonplace.

Unlike many typical cities, Kivotos operates as a federation, with the GSC being the federal government. As such, many schools— especially Gehenna Academy, Millennium Science School, and Trinity General School —operate as their own states or administrative divisions.

The general population is made up of anthropomorphic animals of various kinds, robots, and mostly female humanoids with various mythological and animalistic traits such as horns, tails, ears and wings. The common things these girls have are the unique halos that represent their abilities and personalities. The humanoid girls are the main focus of the story.

Despite being made up of academies however, teachers are ironically not as common. Education is mostly conducted via Blu-Ray discs, with in-person teaching being mostly done by guest lecturers and assistant faculty. Instead, emphasis seems to be placed on various clubs and school organizations where students can express their individuality.

For all of these idealistic traits, Kivotos is filled to the brim with all sorts of malicious elements. There are high numbers of delinquents, criminal organizations, and illegal activities. There is an entire district saved for the Black Market. Gun violence is also a regular occurrence.

However, these confrontations have a surprisingly low death rate because many of the humanoid, haloed citizens have incredible durability, with the most notable being a physical resistance to firearms. Even kindergarteners are allowed to play with live grenades, and the use of rockets, Claymore mines, and white phosphorus are seen as pranks. Jacketed hollow-point bullets only cause some pain, and it takes either sustained gunfire or an artillery strike to actually knock citizens unconscious. The quickest way to kill them is to destroy the halos, usually by over stressing how much protection a halo can withstand, though long term poor health, starvation, and other semi-organic natural causes could also cause death.

According to the Bond story of Sunaookami Shiroko (Riding ver.), Kivotos is implied to be approximately the size of the United States and Canada from our world combined.

Millennium Science School: Millennium Science School is an academy focusing heavily on STEM fields and associated research and development. Although established only relatively recently, it is highly regarded for its cutting-edge science and technology that is unrivaled by other schools, and it holds influence comparable to Trinity General School and Gehenna Academy. Millennium is the newest of the Three Great Academies of Kivotos, valuing logic and technical skill over all else. Because of it, they stand at the forefront of scientific research and attract many students who desire to study math or science. Although Millennium lacks the long-standing traditions and history of Trinity and Gehenna, their scientific advancements have resulted in much of Kivotos' infrastructure being produced or otherwise originating on their campus.

Every year, the school holds a large-scale contest known as the Millennium Prize, where clubs all throughout the school compete with the results of their club activities.

In the Code: BOX event, it is revealed that Millennium operates its own railway.

In the past, a group of researchers came together in an effort to solve seven difficult problems unsolvable by current technology, called the Millennium Problems. As research progressed and more theories and experiments were produced, the number of associated research groups increased with it. Eventually, Millennium as a school was formed by these research groups, and Seminar was placed at its head.

Engineering Department: The Engineering Department is considerably the most known Department within the Millennium Science School as many inventions or equipment that are used all over Kivotos (including their own school) originated from them. True to the motto of their school, its members attempt to create new inventions although what limits them is mostly funding itself.
