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 keep an eye on the Night by their master. Autonomic Nerves are based on the same technology as the mythical beings, golems. 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.

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 being fixed and modified by Lex.

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, units awaken and are to exterminate the ones who disturb the Night. During the time 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 Decision Control Type Unit (意思制御型ユニット) called 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.
