Automated Nerve Circuit [Autonomic Nerve] (自律神経回路(「オートノミックナーヴ」)) is man-made weapon created to fight the Void and keep an eye on the Hollow Night.



Autonomic Nerves are over 1000 years old puppets who have been assigned to watch over the Night by their currently unknown master. Autonomic Nerves are based on the same technology as the mythical beings known as golems, in the sense that they are artificial bodies infused with a human soul. During the time they were created, magic was commonly used by people. It is told that most of the units were destroyed by In-Births, but guessing from Vatista's unit number, at least 10 000 units must have existed at some point in the future.

According to Vatista, only she and 2 other units are currently active. One of those two units is in the custody of the Licht Kreis and is currently being repaired by Lex Bartholomeus.

Autonomic Nerves spend their time in stand-by mode and moderate the situation of the Hollow Night. If a Void or an In-Birth tries to consume too large amounts of EXS, these units awaken and are ordered to exterminate the ones who disturb the Night. During the time that they are activated, they can fight without food, sleep or clothes. Once they finish their mission they are supposed to receive the Completion Command, "Exit Call" (修了命令(「イグジットコール」)) and return to stand-by mode.


Every Autonomic Nerve is equipped with a Decision Control Type Unit (意思制御型ユニット) known as an Aegis-Attributer (エイギスアトリビューター). It's the type name for the red wings each Autonomic Nerve has on their back. Vatista's wings are the 7th type called Crimson Wing: "Seven Flowers" (紅翼:七花). It's unknown how many types there are in total.

Autonomic Nerves are beings who use FLS as their source of power. That's why every unit is also equipped with a Curse Commandment.
