7th Agency

Sector Seven (第七機関) is an organization that specializes in doing research on Seithr and Ars Magus. They mainly focus on using science, as opposed to the Novus Orbis Librarium who focus mainly on Ars Magus; Sector Seven considers the NOL to be their main adversary and polar opposite.

Information
Sector Seven was formed by Yūki Terumi. In the Ikaruga Federation, experiments on the Boundary Interface Prime Field Device Mu-12 were carried out by them. The 'Fluid Seithr Theory' was hypothesized by one of Kokonoe's assistants.

At some point during the Second War of Ars Magus, Kokonoe captured the 'Mad Dog' Azrael and placed him within the Sector Seven jail known as 'The Doghouse'; A cell with a field placed in it. The field placed in the cell has an effect which cools down the cell to a temperature so low, that even atoms cannot move within it. It would not be until the events of BlazBlue: Chronophantasma that Azrael would be released, albeit under the control of Sector Seven.

In the short story That which is inherited, Sector Seven discovered the Nox Nyctores: Deus Machina: Nirvana buried within the 3rd Hierarchical City of Naobi; they deployed a shock squad lead by the, then ordinary, Iron Tager. After the team was swiftly wiped out by the Nox (save Tager), Tager was given to Kokonoe to be revived as the over sized cyborg he is today. Soon after, Relius Clover came to contact the organization, asking to inspect the Nox in exchange for the thirteenth Murakumo Unit: Nu-13; after the exchange went through, Relius returned a few days later with the Nox, accompanied with the battle doll: Fluctus Redactum: Ignis. Kokonoe, Roy and Relius departed for the basement of the Sector Seven complex and opened up Nirvana's core, however, the NOL had begun to attack the complex via a tip from Relius. Nirvana and Ignis became full fledged weapons (thanks to Kokonoe using the Snap Weapon: Infinite Gravity spell) and absorbed the souls of Ada Clover, Ignis Clover and countless NOL soldiers and Sector Seven scientists;. As well as this, Relius also used the power to create Nu-13. After the mass mayhem, Nirvana responded to Kokonoe and struck Relius down, however, he lived to see another day, disappearing with all three of the machines that had recently had life breathed into them. This event left Kokonoe believing that she had killed Relius.
