Magic power regulator

A magic power regulator (魔力調節器) is a device that keeps the magic element absorbed into the body of the one who is equipped with this to prevent it from spinning out of control.

This regulator is visible on the following characters:
 * Kuon Glamred Stroheim — back of her head; the device is seen only in XBlaze – Code: Embryo.
 * Ragna the Bloodedge — both of his gloves.
 * Izayoi — back of her armor in battle mode.
 * Mu-12 — her pauldrons in battle mode.
 * Nu-13 — her eyepatch, and also back of her pauldrons in battle mode.

Trivia

 * Certain characters are seen wearing a device looking exactly the same, but in blue color:
 * Noel Vermillion — her headgear; Kokonoe’s creation; these are supposed to protect her from Event Interferences.
 * Lambda-11 — on her back; back of her pauldrons in battle mode; Kokonoe’s creation.
