Trigger

A Trigger (トリガ) is a Neighbor's technology that is powered by trion. It is mainly used for combat purposes, but it also has other functions.

Activation
To activate the user says "Trigger On". When activated the Users real body is stored within the Trion Supply System and replaced with a Combat Body constructed from the user's Trion. Because the Combat Body is made of Trion, it doesn't get tired or hungry and offers superior strength to that of a normal body. To deactivate the user says "Trigger Off".

The ability and strength of a trigger is directly influenced by an individuals trion value, as shown by Yuma, people that use the same trigger to fight will have a different outcome depending on their trion values. Once a person runs out of trion they will be unable to produce their trigger weapon and leaving them defenseless.

Mechanics
Although Triggers may seem like an advanced technology, it's possible that their mechanics are actually quite simple. In episode 35, Replica stated, "this world's [Earth's] technology is so complex". From what we've seen planet countries in the Neighborhood are quite primitive in some ways, with castles and other outdated technologies as well. Triggers are NOT necessarily an advanced technology. Rather, Triggers are just a result of technology that has developed differently than the technology on Earth.

The actual Trigger is installed in a chip located inside the device which contains eight slots that can install at most eight different Triggers. All the Triggers are divided between Main and Sub Trigger, where each takes four slots. The Main Triggers are automatically set to the users dominate hand. The Sub Triggers are automatically set to the user's non-dominate hand, whichever hand that is.

The user can only activate two Triggers at a time, one from the Main and one from the Sub. The exception to this rule is Option Triggers. Option Triggers such as Raygust's Thruster can be used freely as they are typically built into the Triggers themselves. Trion Relay and Supply System

After the Trigger is activated the Combat Body is created from Trion and controlled through the Trion Relay and Supply Systems. The Trion supply System [red] is like a heart. It contains the Trigger users actual body when the Trigger is activated. It can manipulate trion, supplies Trion to the rest of the Trion body, and creates Triggers as directed by the Trion Relay system.

The Trion Relay system [yellow] functions similarly to a brain. It receives information from the trigger users real body and also acts as an operating system for the Combat Body. The Trion relay system is what allows the Trion body to move and operate Triggers.

If either one of these systems are damaged in combat the Trion in the Combat Body will become disrupted and will cease to function. This can result in either a bailout or cause the Trigger to deactivate returning the user to their natural body. This will not cause permanent damage to the actual Trigger as Both Systems are just Trion constructs that are simply recreated each and every time the Trigger is reactivated.
