The main characters of the series form a squad with Osamu Mikumo as their leader. It is currently part of the Tamakoma Branch.
Osamu Mikumo B-Rank, Shooter
One of the main characters of the series with most of the story being seen from his perspective. Begins as a C-Rank agent but quickly reaches B-Rank, mostly by (unwillingly) taking credit for the actions of the neighbor Yūma Kuga. Joins the Tamakoma Branch later on and forms a squad with his friends Yūma and Chika with him as the leader.
Awesome by Analysis: He is great at analysing the situation and creating new strategies on the fly with what limited resources he has. BFS: His Raygust-trigger, which is basically a huge energy-sword that can double as a shield and thruster, and even a combat knife (though this function has only been shown by Reiji). Classical Antihero: He has low self-confidence, and isn't the best of fighters, but is willing to fight for what he thinks is right nonetheless. This leads to people, principally Yūma, Chika and maybe Kitora and Kazama, have good expections on him. Gun And Sword: He mostly specializes on being a Shooter, though he still uses his Raygust for close-combat and defensive purposes. Humble Hero: Humble to the point of being a doormat. Luckily My Shield Will Protect Me: A secondary function of the Raygust is an energy shield. Morph Weapon: Raygust. Nice Guy: Extremely polite and helpful, even towards jerks and people he barely knows, not because he is naive but because he wants to do what is right. Overshadowed by Awesome: Compared to the skilled and experienced Yūma and Chika's gigantic Trion-supply he is just a rather mediocre agent who can only survive by relying on his skills and wits. Smart People Wear Glasses: One of the few people wearing glasses and definitely smart. Sword and Gun: Raygust and Asteroid, though his Asteroid is the shooter variant (which is a cube). Specs of Awesome: He has his moments. Took a Level in Badass: He is definitely one of the characters who has the most catching up to do, so this is pretty common. Yūma Kuga C-Rank, Attacker
A human neighbor from an unknown world who illegally came to Earth and joined the same class as Osamu.
Adaptive Armor: His Black Trigger. Armed Legs: Can power up his legs with his black Trigger. Almighty Janitor: Starts as a C-Rank trainee after joining Border, despite being easily A-Rank in skill and S-Rank when using his Black Trigger. He still insists on going the normal through the rank-wars to earn a solid reputation as a neighbor in Border. Ambiguously Human: Looks like a human but is a humanoid neighbor in truth. The white hair and red eyes might give a hint. Badass Adorable: A rather cute looking young boy on the outside, an experienced and deadly soldier on the inside. Beware the Silly Ones: He acts like a goofball most of the time but will instantly switch back to his brutally efficient badass self when necessary. And he will utterly kick your your ass if if you ever harm or ridicule his friends. Dark Is Not Evil: His black armor when using his Trigger. Death by Origin Story: Got killed by a mysterious foe before the series began, though his father sacrificed himself to create a Black Trigger that keeps Yūma alive. Dual Wielding: Prefers using two Scorpions when not using his Black Trigger. Heroic Albino: White hair, red eyes, definitely heroic. Living Lie Detector: His side-effect, inherited from his father due to his Black Trigger, lets him notice if someone lies. Living on Borrowed Time: While he can survive with his Trion-body thanks to his Black Trigger, his real body still slowly decays over time. Once it is gone, the Trion-body will vanish as well. Magic Enhancement: An ability of his Black Trigger. Can be used both on himself and other Trion-users. Morph Weapon: Both his black trigger and the Scorpion. Older than They Look: Since his Trion-Body doesn't show signs of aging. Pint-Sized Powerhouse: Because his growth has stopped since his death. Not a problem, since Trion-bodies don't rely on physical body mass anyway. Power Copying: His Black Trigger can analyse and copy Triggers that are used against him. Power Fist: His standard attacks with the black trigger involve punching things with a powered fist. Skilled, but Naive: While he is a very skilled individual, he has little knowledge on how Society works in our world. Swiss-Army Weapon: Just look at all the abilities of his Black Trigger listed here... Trick Bullet: Can use special black Trion projectiles that penetrate shields and slow their victim down with huge weight instead of causing damage. Copied this technique from Miwa. Replica Trigger
An intelligent Trigger that serves as a guardian and guide to Yūma Kuga.
Non-Human Sidekick: To Yūma Kuga. He acts as his guardian and also gives him certain powers. Chika Amatori C-Rank, Sniper
The sister of an old friend of Osamu.
Badass Adorable: She's the cutest little kid you could think of... and also able to fire an almost unstopable Death Ray. The Cutie: A genuinely sweet kid with an oversized sniper rifle. Doom Magnet: Her enormous Trion attracts a lot of strong neighbors that try to capture her and are a danger to everyone around her. Friendly Sniper: For all her destructive potential she is the sweetest girl you could think of. Idiot Hair: In the middle of her head. Long-Range Fighter: As a sniper she at least she SHOULD be this, sadly she often finds herself to be rather close to the action. Pint-Sized Powerhouse: Small stature, ridiculous amount of Trion. Unskilled, but Strong: HUGE Trion-supply, but still an inexperienced trainee and not the best shot even among the new snipers. Other Yūichi Jin S-Rank, Attacker The Ace: Never anything less than confident, being immensely skilled and able to see the future to some degree Combat Clairvoyance: His side-effect allows him to see the immediate future, which includes most incoming attacks. Cool Shades: His signature accessories. Razor Wind: His Black Trigger "Wind Blade" is a sword that can shoot these from all connected surfaces it touches. Though it is debatable if it really is "wind" or just extending energy blades. Sunglasses at Night: Never seen without them, no matter the time of day.
Staff Takumi Rindō Tamakoma Branch Chief Tamakoma A-Rank Unit
The only known unit of Tamakoma Branch prior to the recruitment of Osamu, Yūma and Chika. They are considered to be the strongest squad in all of Border.
Reiji Kizaki A-Rank, Allrounder The Big Guy: Easily one of the most beefy agents of border. BFG: His unnamed Minigun Trigger. BFS: The Raygust. Gatling Good: An unnamed Minigun Trigger. Good Old Fisticuffs: Not completely unarmed, but he uses his Trigger to enhance his fists. Homing Projectile: One of his Gunner triggers seems to be a Hound, which has that function. Long-Range Fighter: He's known to be the only Allrounder who is also skilled as an Sniper. That, however, has yet to be seen on-screen. Morph Weapon: The Raygust. Sword and Gun: Assault Rifle and Minigun Gunner-Triggers and a Raygust. The Stoic: He remains calm even when firing a gatling gun or after being cut in half! Kirie Konami A-Rank, Allrounder Action Girl: One of the most skilled agents in all of border. An Axe to Grind: The Sōgetsu, two hatchets or which become a huge two-handed version, after combining those. Dual Wielding: The Sōgetsu, in their standard form. Morph Weapon: The Sōgetsu. Skilled, but Naive: Played with. Despite being an experienced and skilled member of Border, she'll believe in almost anything one tells her, and thus she is frequently made fun of. Kyōsuke Karasuma A-Rank, Allrounder Barrier Warrior: Seems to specialize in defensive Triggers like the 'Escudo'. Bishie Sparkle: When outside of combat, he usually has this around his hair. The Stoic: Just like Reiji, never loses his calm or patience. Sword and Gun: Assault Rifle Gunner-Trigger and a Kogetsu. Shiori Usami A-Rank, Operator Voiced by: ???

The Face: His entire unit is called "The Face of Border" because of their spotless reputation and idol-like status, but the trope fits him best. Nice Guy: Always polite and positive.

Armed Legs: Had to use her Scorpion as a replacement leg in one battle and has seemingly taken a liking to it. Child Prodigy: Reached A-Rank at a really young age. Grappling-Hook Pistol: A secondary function of her pistol.

He is Jin's favorite candidate for a new user of his forer black trigger, the "Wind Blade". Anti-Hero: He is willing to fight even supposed allies to get his revenge on all Neighbors alike.

The Ghost: Only mentioned but never seen thus far.
Single-Biome Planet: The different neighbor worlds seem to be this, at least described by Replica. Reveille
The maritime nation surrounded by a rich, vast sea.
The cavalry nation where battles are fought on special Trion Soldiers.
The snow country where harsh terrain and climate thwart enemies from attacking.
The god's country and the largest military state.
Hairein Captain The Beastmaster: At least appears like one, because his Black Trigger "Alektor" creates Birds, Fish and Lizards out of Trion to attack and defend. It's most likely just a shaped energy though. The Captain: Of his group. Stun Guns: Not a gun and not conventional stunning, but his Trigger can turn it's victims into Trion cubes without causing actual damage. Which is very useful when capturing enemies. Lamvanein Arm Cannon: His Trigger "Chelidon". Beam Spam: The cannon-batteries that he can grow out of his shoulders can fire a huge array of beams at multiple enemies and wipe out entire squads at once. Jet Pack: A feature of his Trigger which allows him to fly and bomb his enemies. Morph Weapon: His Trigger, which can whip out various cannons at different parts of his body. More Dakka: His main strategy in fights. Enedra Morph Weapon: His Black Trigger "Vorvoros" can turn his entire body into liquid or gas. Nigh-Invulnerability: Of either the "Made out of Air"- or "Made out of Liquid"-variety. His only weakpoint is a small, always moving orb in his body. Person of Mass Destruction: Can cause massive damage with his Black Trigger and has no qualms doing so. Sadist: He really enjoys mindless destruction and talking down to his opponents. Hughes Extra Ore Dinary: His Trigger "Lampyris" makes him capable of controlling magnetism. Morph Weapon: His Trigger consists of countless metal parts that he can freely form. Sempai Kohai: This seems to be basically his relationship with Hairein, where he is the Kohai and Hairein the Sempai. Tranquil Fury: His usual mood. Winged Humanoid: Can create metallic wings on himself and allies, though the flight actually works through magnetism. Mira The Dark Chick: Her dark clothes and mean but loyal personality seem to point at that. The Evil Genius: She seems like the closest thing to an operator the invasion force has. Thinking Up Portals: Her Black Trigger can create portals, which can be used to retreat allies. They can also be used as spikes to impale enemies. Visa Badass Grandpa: This clearly is the case. Seems very old and still battles on even grounds with the thus undefeated Yūma. Cool Sword: His Trigger "Organon" is actually a sword hidden in a walking staff. Magic Staff: His Trigger might count, though it actually hides a sword. Can create energy blades everywhere around him. Unknown Country Raymond Self-Defense Leader Izukacha Raymond's Daughter Vittarno Raymond's Son Yūgo Kuga Yūma's father
