Murakumo Unit



The Murakumo Units are special types of Boundary Interface Prime Field Device's that use the Nox Nyctores, Lux Sanctus: Murakumo. The Murakumo Units were created after the Dark War as Anti-Sankishin Core Units. Their original purpose are as Boundary Interface Prime Field Devices used in order to explore the other side of the Boundary, since humans can't survive on the other side. Murakumo Units were made as a result of the first Prime Field Device, having gained a soul and became the Eye of the Azure, becoming godlike. After this incident, from fearing what the prime field device could do, they sealed it deep inside the Boundary. They then decided to create copies of the prime field device and as soon as one returned from the Boundary, its emotions would be sealed, turning it into a weapon that could be controlled. As of now only 13 have been created, and only 3 are known. Lambda-11 is an imitation Murakumo Unit, relying on her Idea Engine to substitute for the Nox. Mu-12's first tempering was interrupted by a blast from the Nox Nyctores, Gigant: Take-Mikazuchi, which destroyed Ibukido, and was deemed a failure. Mu-12 was later tempered again and gained the true Azure and became something better than a Murakumo Unit, named Kusanagi, the Godslayer. Nu-13 was forged at the bottom of The Sheol Gate and became something of a success but only has the false Azure. According to both Ragna and Nu, Ragna had "killed" two Murakumo Units before meeting her. Murakumo Units seem to be able to enter a white void inside their minds with them only wearing a white robe as seen in Calamity Trigger with Noel and Nu.

It is worth noting that in Makoto Nanaya's arcade ending in Continuum Shift II, Hazama sent Makoto to Ikaruga where she found the other Failed dormant Murakumo Units.
