Border is a big agency in Mikado City. It was created for the sake of protecting the city from neighbors attacks. They fight the Neighbors by the means of Trion and triggers, the technology of Neighbors. Border was designed to be a secret organization with the purpose of travel an intermediary relationship between ‘Earth’ and Neighbors. Along with its establishment, Border has made an Alliance with three neighbors nations and uses the building that has now become Tamakoma’s base as its headquarters.

Between its establishment and 6 years before the start of the series, Border had 19 people within its ranks. However, about a year later, an allied nation was invaded by a hostile nation and when Borders sent its forces to assist, 10 out of 19 members died, with some becoming black triggers. After the incident, the organization split into two, one became the current headquarter and the other became Tamakoma branch.

About 4.5 years before the start of the series, Border made its first public appearance when the first large-scale invasion occurs. Soon after that, Border built their Headquarters in the middle of an area known as the Danger Zone and started to recruit new members to build up the army and strength for future invasion.

Ranking System

Rank Battles inside Border are official matches fought between agents as training and to increase their ranking. Rank Battles are divided into Solo and Team Match. In Team Match, they are fought between 3 or 4 teams at a time, with the team with the lowest ranking having the right to choose the stage. Rising to no.1 or no.2 in the B-Rank battles gives the team the right of challenge to rise to A-Rank.

Triggers Origin

A Trigger is a Neighbor’s technology that is powered by trion. It is mainly used for combat purposes, but it also has other functions. Borders provide battle triggers to their combatant, while C ranks get a training trigger.

The mechanics of the Trigger differ from neighbors nation to nation. As for Border’s Trigger,their 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 each from main and sub.

Each Trigger uses a certain amount of the User’s trion, even just by equipping. Each person are able to 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 who use the same trigger to fight will have a different outcome depending on their trion values. Therefore once a person has runs out of trion, they will be defenseless and unable to activate the trigger.

Black/Normal Triggers

Black Trigger

They come from user with immense trion abilities and in order for the power to be left in the real world after death, created a special trigger to pump the trion and life into black trigger. they represent the user personalities and must be compatible to activate the power. In order for their power to be left in the world after their death, created a special trigger that pump their whole trion and life into it.

Black Triggers strongly reflects the sensitivity and personality of the person that created it. One of its weaknesses is that it cannot be activated if there isn’t compatibility between the user and the creator’s personalities, but its performance is incomparable to a common trigger. These triggers are very rare due to the sacrifice required to create them, though it has also been noted that Neighbors avoid driving enemy countries into a pinch because it increases the likelihood of black triggers being created.

Triggers Class/Abilities

Default Triggers

  • Bagwrom – A cloak that renders the User invisible to Radar. It consumes trion while in use.
  • Shield – A barrier that able to block opponent’s attacks. Its size can be adjusted, but it will affect its durability.

  • Bail Out – This function destroys the trion body and returns the original to Border’s base; it is triggered automatically when the trion body is destroyed in battle.
