Osamu Mikumo

http://static.tvtropes.org/pmwiki/pub/images/osamu_mikumo_639.jpg
B-Class, Shooter
15 Years
Voiced by: Yuki Kaji (Japanese), Brian Doe (English)

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.
  • Badass on Paper: Osamu's accomplishments are typically hyped up to sound a lot better than they actually were, such as when he had a draw with Kazama. Yes, the last match was a draw, but he lost 24 times before that.
  • 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.
  • Shirtless Scene: Takes off his shirt in episode 58 to blindfold a Trion Soldier and remains shirtless for the succeeding episode.
  • Small Steps Hero: Osamu Mikumo is an archetypical Small Steps Hero, as he makes it flat out clear many times that he will not ignore the plight of any helpless person to save his own life or to prevent a future tragedy/conflict. This comes back to bite not just him, but everyone on Earth after using his trigger in real battle teaches the Neighbors that C-Rank Border agents can't Bail Out (a mechanism which allows them to teleport to safety when taking fatal damage). Because of this, a large-scale invasion happens that claims more lives than he originally saved, but Osamu makes it clear he'd do it all over again.

  • 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.
  • Walking Shirtless Scene: For episodes 58 and 59, considering he takes off his hoodie to blindfold a Trion Soldier. Made even more hilarious by the fact that he didn't take his shirt off at the beach.
  • Walking Swimsuit Scene: For at least four episodes, from episode 56-59 by virtue of being captured by Gieve while still wearing a hoodie with green swim shorts.
  • 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

http://static.tvtropes.org/pmwiki/pub/images/yuumma_7911.jpg
B-Class, Attacker
15 Years
Voiced by: Tomo Muranaka (Japanese), Cathy Weseluck (English)

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 Neighborhood he has a brilliant strategic mind for battles. Finally, during the second Neighbor Invasion he manages to defeat Viza in his normal Trion body and use the last of his power to finish off 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.
  • Brought Down to Normal: As a member of Border, Kuga is restricted from using his Black Trigger mostly due to Interservice Rivalry. So he has to learn how to use the normal triggers other Border members use.
  • 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.
  • Shirtless Scene: Goes to an indoor beach in episode 56.
  • 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

http://static.tvtropes.org/pmwiki/pub/images/replica_7788.jpg
Tropoi Autonomous Trion Soldier
Voiced by: Hideyuki Tanaka (Japanese), Marco Soriano (English)

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

http://static.tvtropes.org/pmwiki/pub/images/chika_2_9661.jpg
B-Class, Sniper
13 Years
Voiced by: Nao Tamura (Japanese), Caitlyn Bairstow (English)

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.
  • BFG: She uses an Ibis, the heaviest Sniper Trigger Border has available. When she fires it, it's less of a plain Anti-Tank gun, and more like a Wave Motion Gun.
  • 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.
  • Reluctant Warrior: Mostly by virtue of being a sweet, pacifistic little girl. She has no problem with shooting lifeless targets, buildings and Trion soldiers, but she can't bring herself to directly shoot humanoid targets (even though they wouldn't die anyway).
  • 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.

Yūichi Jin

http://static.tvtropes.org/pmwiki/pub/images/jin_123_4652.jpg
S-Rank, Attacker
19 Years
Voiced by: Yuuichi Nakamura (Japanese), Andrew Francis (English)

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.

  • Reasonable Authority Figure: Is tolerant of neighbors with friendly intentions and will not support destructive infighting in the power struggle between the Kido Faction and Tamakoma.

  • Action Girl: One of the most skilled agents in all of border.
  • An Axe to Grind: The Sōgetsu, two hatchets which become a huge two-handed battleaxe, after combining those.
  • Dual Wielding: The Sōgetsu, in their standard form.
  • Hair Wings: Part of her hair forms a wing even in her trion form, through it doesn't serve any purpose and its just decorative.
  • Man Bites Man: A comedic variant, in which she is fond of biting Osamu head when Kyosuke pranks her.
  • Morph Weapon: The Sōgetsu.
  • Power Makes Your Hair Grow: Inverted. Her hair gets short while in her Trion Body form.
  • Skilled, but Na´ve: 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.
  • Super Gullible: She believes anything other people tell her, no matter how ridiculous. This includes believing Jin when he said Osamu, Chika and Yuma were his siblings when they don't look alike at all.
  • Tsundere: She shows a few signs that she might be one.
    • She tries to cover up her shyness with strength, as shown when Kyōsuke told her Osamu had called her pretty.
      • She becomes very violent when Kyōsuke tells her he lied to her, though she discounts it on Osamu instead.

  • Shirtless Scene: In episode 56.

  • Sword and Gun: Assault Rifle Gunner-Trigger and a Kogetsu.
