As the Magisters continued to research Arche, they also attempted to use related technologies to increase the Battle Power of the Descendants. The miniaturized Arche Control System was used in Modules, External Components, and Ultimate Weapons.
Code name "Python" was a piece of equipment invented to be compatible with toxic Arche. When the gun is fired, a small amount of toxic material is sprayed. The minute a bullet penetrates a target's skin, a neurotoxin is released into their body.
However, because the emission of too much poison when loading the rounds into the weapon's chamber can have a harmful effect on the user, a series of control procedures made it possible to safely and effectively use the powers of Arche. Thus, only Descendants who possess Arche abilities can use this weapon effectively.
