    Main Characters 

Mikumo Unit / Tamakoma-2

The main characters of the series form a squad with Osamu Mikumo as their leader. They are currently part of the Tamakoma Branch.

Osamu Mikumo

B-Class, Shooter
15 Years
Voiced by: Yuki Kaji

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 analyzing 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 expectations on him.
  • 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. He also has the regular Shield Trigger.
  • Memetic Badass: Along with the rest of his team Osamu becomes this In-Universe during the C-Rank wars after managing to draw with Kazama during their duel. Of course Osamu being Osamu is naturally embarrassed by this praise especially since the story is a bit distorted. After his loss against Midorikawa and revealing the truth of the duel to the other C-Rank trainees his reputation as this stops... only for him to get a new one since Yuma calls Osamu his leader and he is apparently important enough to be in a private meeting with Kido and the other higher-ups of Border.
  • 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.
  • The Scapegoat: Invoked but subverted. Eizo Netsuki tried to shift blame for the 32 C-class agents being kidnapped to Osamu, but because of Katsumi Karasawa, Osamu not only had the opportunity to stand for himself, he turns the situation around and says he will save the kidnapped agents himself, which earns a very favourable reaction from the public.
  • Smart People Wear Glasses: One of the few people wearing glasses and definitely smart.
  • Sword and Gun: Being a Shooter he mostly specializes on using his Asteroid (in cube form), though he still uses his Raygust for close-combat and defensive purposes.
  • 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.
  • Weak, but Skilled: The major difference in Osamu's fighting style in comparison to Yuma and Chika is that unlike them he has a below average amount of Trion compared to normal soldiers. Osamu makes up for that by his creative manipulation of Trion, his willingness to receive disabling injuries and also conserving his power to make critical shots. As Kurasama points out Osamu is weak but not stupid.

Yūma Kuga

B-Class, Attacker
15 Years
Voiced by: Tomo Muranaka

The main character, a humanoid neighbor from an unknown world who illegally came to Earth and joined the same class as Osamu.

  • The Ace: Yuma is definitely this not just amongst his own team but to other agents of Border as well. Not only is he in possession of a Black Trigger, and has full mastery over it, when he joins the ranks of Border he willingly switches to using a weaker Trigger and still kicks an insane amount of ass. Not only that but thanks to his years of combat experience in the Neighbourhood he has a brilliant strategic mind for battles. Finally, during the second Neighbour Invasion he manages to defeat Viza in his normal Trion body and use the last of his power to finish of Hairein. By the time of the B-Rank Wars he is officially considered to be The Ace of Tamakoma-2.
  • 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 ass 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.
  • Memetic Badass: In-Universe. Along with the rest of his team Yuma becomes this during the C-Rank wars, firstly for managing to destroy the simulated Trion soldier in combat training in 0.4 seconds, and secondly for Curb Stomping Midorikawa 8-2.
  • 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 Na´ve: While he is a very skilled individual, he has little knowledge on how Society works in our world.
  • Spring Jump: Picks up the Grasshopper after reaching B-Rank, which allows him to jump in midair.
  • 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

Tropoi Autonomous Trion Soldier
Voiced by: Hideyuki Tanaka

An intelligent Trion Soldier that serves as a guardian and guide to Yūma Kuga.

  • Heroic Sacrifice: A non fatal version of this happens during the end of the Invasion Arc. Replica is sliced in half by Moira's attack and is left heavily damaged knowing that the time it would take in order to open the door to Border HQ would be to long he has Osamu throw him into the portal linking the Neighbors ship to the outside world in order to force the ship to leave the planet. This forces the Neighbors to leave without acquiring Chika but because of his heavily damaged state he can't fly away and is stuck in the Neighbours ship as it teleports away.
  • Non-Human Sidekick: To Yūma Kuga. He acts as his guardian and also gives him certain powers.
  • The Smart Guy: Thanks to his travels with Yuma and his father Replica has extensive knowledge, not just of the Neighbor Worlds, but triggers too. Not only is he the A.I. that controls Yuma's Black Trigger but his extensive knowledge of the Neighborhood allows him to update Border's systems, create a replica Rabbit after analyzing one of the original models, and, with Osamu's help is ultimately the one who forces the Aftokrator neighbours to retreat.

Chika Amatori

B-Class, Sniper
13 Years
Voiced by: Nao Tamura

The younger sister of Osamu's tutor. He himself became her tutor, after her brother disappeared. Neighbors have been frequently targeting her since she was little because she has the largest Trion-supply ever recorded.

She joins Border as a sniper early in the series to learn how to protect herself and to have a chance to search for her missing brother and friend. After the invasion she got a promotion to B-Class, partially because she is considered a valuable asset due to her enormous Trion.

  • Badass Adorable: She's the cutest little kid you could think of... and also able to fire an almost unstoppable Death Ray.
  • Blessed with Suck: Chika is in possession of an insanely high amount of Trion which even for advanced border agents is considered abnormal. Unfortunately this same power makes her a target for Trion soldiers, her brother and friend both end up getting kidnapped trying to help her, and during the Invasion Arc she is turned into a Trion Cube and almost captured by the Humanoid Neighbours. Girls got it rough to say the least.
  • The Cutie: A genuinely sweet kid with an oversized sniper rifle.
  • Does Not Know His Own Strength: Even after joining Border and starting her Sniper training, she still doesn't know half the extent of her Trion prowess.
  • Doom Magnet: Her enormous Trion attracts a lot of strong neighbors that try to capture her and are a danger to everyone around her. She has become traumatized after her brother and her best friend were captured by Neighbors.
  • Friendly Sniper: For all her destructive potential she is the sweetest girl you could think of.
  • Idiot Hair: In the middle of her head.
  • In-Series Nickname: Called "Chikako" by Izuho.
    • She is also called "Tamakoma's Trion Monster" after she blows a hole in the wall of Border HQ using an Ibis.
  • Long-Range Fighter: As a sniper she at least SHOULD be this, sadly she often finds herself to be rather close to the action.
  • Memetic Badass: In-Universe along with the rest of her team. See the "Tamakoma's Trion Monster" thing above.
  • Pint-Sized Powerhouse: Small stature, ridiculous amount of Trion.
  • Tareme Eyes: A trait shared by none in the manga.
  • 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
19 Years
Voiced by: Yuuichi Nakamura

The self-proclaimed "Elite-agent" of the Tamakoma Branch. He wields the "Fujin" ("Wind Blade)", one of the two Black Trigger in all of Border, and possesses a Side Effect which grants him limited insight into peoples future.

  • The Ace: Never anything less than confident, being immensely skilled and able to see the future to some degree
  • The Chessmaster: Partially thanks to his side effect, partially thanks to his own wits, Jin is able to see possible futures and attempt to steer events towards the most ideal one. During the large scale invasion arc, the Aftokrator even note that someone was pulling the strings the entire time.
  • Combat Clairvoyance: His side-effect allows him to see the immediate future, which includes most incoming attacks.
  • Cool Shades: His signature accessories.
  • Guile Hero: By effectively utilizing his side effect and his wits, he can manipulate events to achieve the best outcome he could.
    • For example, negotiating with Commander Kido to recognize Yuma as a member of Border despite the fact he is a neighbor. He did this by giving up his own Black Trigger, after he beat the people sent to kill Yuma and take Yuma's Black Trigger using it, making his own Black Trigger look more valuable. He also warned Commander Kido against escalating the conflict by telling him what would happen if he did, forcing Kido to back down. He also tells Kido that Yuma and his other juniors will be helpful for Kido's true objective, which ultimately convinces him to accept Jin's proposal and ending the conflict.
    • During the Large-Scale Invasion arc, he told his allies where to be and what to do before hand, based on what his side-effect tells him. Thanks to that, he allowed Border to achieve one of best possible outcomes, even if it wasn't THE best outcome.
  • Morph Weapon: The Scorpion Trigger, which was created by himself.
  • 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.
  • Trademark Favorite Food: His Bonchiage (fried soy sauce rice crackers). He's hardly ever seen without them. Anime filler even added a scene where his room is full of boxes of the stuff.

  • Morph Weapon: The Sōgetsu.
  • Power Makes Your Hair Grow: Inverted. Her hair gets short while in her Trion Body form.

  • The Dreaded: Even for the higher ups. Its described as inhuman while he fights.

20 Years
Voiced by: ???

Leader of the Tachikawa Unit, part of the Expedition Force and both the #1 attacker and overall agent of the entire Kido Faction. Has a long-standing rivalry with Jin.

  • The Ace: Number one attacker from Border, not counting Amo, Shinoda, Jin and Konami who are outside the normal ranking.
  • Adult Child: Quite similar to Jin, anxious as a kid to fight a strong and opponent and doesnt seem to take anything seriously. A character description even jokes about him wearing a black coat and two swords while being over 20 years.

  • Big Damn Heroes: Twice during the Second Invation. He saves Murakami from some rabbits and also saves the entire Border building from a Neighbor kamikaze attack.

  • Blood Knight: Really interested in defeating new opponents, even Black Trigger users.
  • Childhood Friends: With Ren Tsukimi according to the manual.

  • The Rival: A longstanding one to Jin at least till the latter received a Black Trigger and reached S-Rank.

Kōhei Izumi

  • Badass: Enough to hold his own with Hairein for a good while.
  • Beam Spam: When using the Hound or the Viper.
  • Blondes Are Evil: Completely averted. He first appears as an antagonist due to duty but after that mess is solved he is a pretty nice individual, even while being very trigger happy.
  • Destructive Saviour: Very prone to destroying buildings and streets during battles.
  • Fun T Shirt: Seen wearing one with the inscription "1000 Shots 100 Hits", which pretty much describes his combat modus operandi.
  • Guns Akimbo: Not so much guns as "projectile-firing cubes" but you get the idea.
  • The Gunslinger: Can use different types of bullets and even fusions for different attacks.
  • Homing Projectile: The Hound automatically homes onto targets while the Viper (and thus also the Tomahawk) can be manually guided.

  • Perpetual Smiler: Always cracking a smile, even while facing enemies.

  • Rich Kids: The primary reason for his position.
  • Small Name, Big Ego: Thinks pretty highly of himself for being in the #1 A-Rank squad and is pretty rude towards lower ranking agents. He is however not very skilled by himself, which his teammates are happy to point out.

Shūji Miwa

A-Class, Allrounder
17 Years
Voiced by: Masakazu Morita

The leader of the Miwa unit and an attacker.

He harbors a strong hatred for neighbors because his older sister was killed by them. He is Jin's favorite candidate for a new user of his former black trigger, the "Wind Blade".

  • Anti-Hero: He is willing to fight even supposed allies to get his revenge on all Neighbors alike. This seems to start gradually changing as everyone around him start accepting Yūma as an ally and member of Border and he is forced to, too.
  • Abnormal Ammo: Has a trigger that turns his bullets into weights that slow down the enemy.
  • Badass: Say what you will about the guy but there's no doubt that he is definitely this. While he gets some pretty Badass points during the first couple arcs in the series (especially since he's the first character to give Yuma a hard time during a fight) its his fight with Hairein that really shows he's not someone to screw with. Firstly he manages to put Hairein on the ropes thanks to his quick attacks and reflexes, secondly when Hairein tries to use Moira's portals to sneak attack him he whips out his gun, fires some tracking shots through said portal and uses them to hit both of Hairein and Moira and finally he whips out "Wind Blade" and, with Replica's help, dismembles Hairein's body allowing Yuma to finish him off.
  • Big Damn Heroes: Saves Osamu from Hairein in the climax of the Second Invasion arc.
  • Big Sister Complex: Character description states sisters are his favorite thing.
  • Cynicism Catalyst: His older sister was killed by neighbors, which fuels his desire to kill them.
  • Exhausted Eyebags: After the Black Trigger retrieval arc, mostly due to Yuma being admitted into Border.
  • Fantastic Racism: Has an immense hatred against neighbours.
  • I Was Just Passing Through: Saves Osamu as Jin asked him to do, but in his words only because he wants to defeat Hairein.
  • Jerkass: Very rude overall, and outright violent towards neighrboors.
  • The Leader: Of the Miwa squad.
  • Red Eyes, Take Warning: His are a light shade of red, and while not evil he is definitively not a very pleasant individual.
  • Revenge Before Reason: His hatred for neighbors really clouds his reasoning at times.
  • Scarf of Asskicking: Perhaps subverted, as he wears it while he isnt on his fighting form.
  • Shout-Out: His badges feature Rilienthal Hino, Gomuzō and Super Alien Cat, from the creator's previous work Manga
  • Sword and Gun: Handgun-shaped Gunner-Trigger and a Kogetsu.
  • Trick Bullet: Uses special black Trion projectiles that penetrate shields and slow their victim down with huge weight instead of causing damage.

An attacker of the Miwa Unit.

He is a rather good-natured member of border, especially compared to the rest of his squad. He has no special resentment against Yūma or Neighbors in general and just likes to do his job and have a good fight.

  • Badasses Wear Bandanas: Wears one both in his Trion form and in his casual attire.
  • Blade on a Stick: Uses his Kogetsu and Scorpion in combination to form a spear that can change it's size and point.
  • Blood Knight: A friendly variant, but he is also always looking for a fight.
  • Boisterous Bruiser: Always searches for a good fight against strong opponents.
  • Book Dumb: Has bad grades and doesn't seem very conventionally smart, but can be very shrewd and insightful at least what combat is concerned.
  • Catch Phrase: "Or so you think." which he says at least once in almost every fight.
  • Dull Eyes of Unhappiness: Even mentioned by the author, through he isnt very unhappy himself.
  • In Universe Nickname: "Spear Geek", courtesy of Izumi.
  • Morph Weapon: The Scorpion-part of his spear.
  • The Nicknamer: Calls Izumi "Bullet Fool".
  • The Power of Friendship: Or rather the power of teamworking, as he says when he defeats Lamvalein thanks to a combined shield he and other Border agents do that allows him to pierce him with his spear.
  • Vitriolic Best Buds: Seems to be this to Izumi of the Tachikawa Unit, who he "affectionately" calls "Bullet Fool".

Hairein

Captain
24 Years
Voiced by: Nozomu Sasaki

  • Achilles' Heel: It's revealed that Hairein's trigger only allows him to turn Trion related objects into cubes for capture meaning that regular objects can still effect him. This ends up leading to his defeat near the end of the arc once Osamu deactivates his Trigger meaning that Hairein's Trion animals have absolutely no effect on him and he's forced to attack Osamu directly making him vulnerable to Mira and Yuma's attacks.
  • Animal Motifs: A Dragon, according to the Extra Material.
  • 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 shaped energy balls though.
  • Big Bad: Of the Large-Scale Invasion Arc since he's the one whose leading the other Aftokrator Neighbours in capturing the C-Rank members of Border.
  • Combat Pragmatist: Not against using underhanded tricks like asking Moira for assistance and stabbing Kyosuke from the back with one of her portals.
  • The Captain: Of his group.
  • Oh Crap!: Has a couple of these looks over the course of the last part of the invasion arc once his plans start falling apart.
    • Firstly once he realises Viza was defeated by Yuma.
    • Secondly when Osamu deactivates his Trigger forcing Hairein to confront him directly.
    • Finally once he realizes that that Osamu's true aim was his ship the entire time and he's forced to flee without capturing "The Golden Goose".
  • Pragmatic Villainy: Why he doesn't want his team to make a full attack on earth. He is actually afraid that forcing the earth defenders too much would make them desperate enough to create Black Triggers thus making them far more powerful.
  • Reasonable Authority Figure: Towards his team, even asking for feedback from Lamvalein about his choices as a leader.
  • Shoot the Dangerous Minion: Decides to get rid of Enedora due to his violent personality.
  • The Stoic: Always calm, even when things start going against his favor.
  • 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.
  • Technical Pacifist: Describes himself as one and at least it can be said he doesn't approve unnecessary violence. Fittingly uses a Trigger that captures Trion bodies but doesn't do physical damage.
  • You Gotta Have Blue Hair: In the anime.

  • Graceful Loser: Congratulates Yoneya for defeating him and doesn't seem at all conflicted about it.
  • Impaled with Extreme Prejudice: By Yoneya.
  • 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.
  • Noble Demon: Just like Viza, he seems to be a nice person that happens to enjoy fighting and is on the invading side. He even admits his defeat and wishes to fight against Yoneya again.

  • I Shall Taunt You: Constantly calling his opponents "Miden Monkey" to provoke them.
  • Jerkass: Which in turns gets him killed when Moira decides they have enough of him pissing off everyone.
  • Killed Off for Real: Was killed by his own allies before Border could take him prisoner. However, due to his horns taking root in his brain, the horns were able to keep his memories and personality intact, and he wants revenge on his former allies.
  • Morph Weapon: His Black Trigger "Vorvoros" can turn his entire body into liquid or gas.
  • Mismatched Eyes: A product of of his horns messing with his head.
  • Nigh-Invulnerability: Of either the "Made out of Air"- or "Made out of Liquid"-variety. His only weak point 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. Moira says this personality was caused by his trigger.
  • Smug Snake: Very confident on his abilities, which in turn gets him killed.

  • Tranquil Fury: His usual mood.
  • Undying Loyalty: To Aftokrator. Hairein was however sure he was going to betray them.

Viza

65 Years
Voiced by: Hiroshi Naka

  • Affably Evil: Is easily the nicest guy amongst the Invading Neighbors, commenting that kidnapping children doesn't sit right with him and congratulating Yuma when he manages to score the deciding blow against him. That being said though he is still invading the human world and can be pretty ruthless when he has to be.
  • Badass: Seemingly the biggest Badass amongst the invading Neighbors to the point that the fact that Yuma actually managed to defeat him causes the usually Stoic Moira and Hairein to have major Oh Crap! moments.
  • Badass Grandpa: This clearly is the case. Seems very old and still battles on even grounds with the thus undefeated Yūma. This is especially impressive when you consider that because of his age he's the only member of the Invading Neighbors not in possession of horns to better control his Trion but makes up for it with his extensive battle knowledge and powerful Black Trigger.
  • Beware the Nice Ones: He is more gentle than most of his fellow countrymen, but also seems to have a darker side which he rarely shows.
  • Blade Spam: His power.
  • Blood Knight: A calmer and subdued variant in contrast to Enedora, but when defeated admits to never get enough of battles.
  • Cool Sword: His Trigger "Organon" is actually a sword hidden in a walking staff.
  • Eyes Always Shut: Always, without exception.
  • Graceful Loser: Takes his defeat at Yuma's hands pretty well, commenting that he can never get enough of combat, and calmly telling his boss that the one who defeated him is coming his way.
  • Instant Death Radius: Pretty much how Organon works, creating circular blades that cut through everything on the area that surrounds him.
  • Magic Staff: His Trigger might count, though it actually hides a sword. Can create energy blades everywhere around him.
  • Nice Job Fixing It, Villain: Lying to Yuuma was his greatest mistake.

Osamu's mother who was first seen visiting him in the hospital after the large-scale invasion. She was highly skeptical of her son joining border but later realized that he has found his purpose protecting people as an agent.

  • Absurdly Youthful Mother: Is often mistaken for being Osamu's sister because she looks rather young.
  • Dissonant Serenity: Always with the same expression, even when confronting her son or when declaring all reporters should be beaten with a stick.
  • Generation Xerox: Looks very similar to her son.
  • I Want Grandkids: Not explicitly stated (yet), but she seems to be strongly in favor of setting Osamu up with Chika.
