Trigger

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

Mechanics
The mechanics of the Trigger may differ from nation to nation. As for Border's Trigger, the actual Trigger is installed in a chip located inside the device which contains eight slots that can install at most eight different Triggers.

The Triggers are divided between Main and Sub Trigger, where each takes four slots. The Main Triggers are automatically set to the User's dominate hand. The Sub Triggers are automatically set to the user's non-dominate hand, whichever hand that is. Typically, the user can only activate two Triggers at a time, one from the Main and one from the Sub. However, Option Triggers such as Thruster can be used freely as they are typically built into the Triggers themselves.

Each Trigger uses a certain amount of the User's trion, even just by equipping. As a result, each person can equip a different amount of Triggers, depending on their trion capacity. Once activated, the User's real body is stored within the Trigger and replaced with a Trion Body constructed from the User's Trion.

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.
