The characters of ''Manga/WorldTrigger''.

For its relatively short length, the series has already become a case of LoadsAndLoadsOfCharacters, so expect this page to be split up over time. For now, it most of all NeedsWikiMagicLove.


[[folder: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
-->[[AC:B-Class, Shooter]]
-->15 Years
-->'''Voiced by:''' Creator/YukiKaji

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.

* AwesomeByAnalysis: 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).
* ClassicalAntihero: 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.
* HumbleHero: Humble to the point of being a doormat.
* LuckilyMyShieldWillProtectMe: A secondary function of the Raygust is an energy shield. He also has the regular Shield Trigger.
* MemeticBadass: Along with the rest of his team Osamu becomes this InUniverse during the C-Rank wars [[spoiler: after managing to draw with Kazama during their duel]]. Of course Osamu being [[HumbleHero 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 [[TheAce 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.
* MorphWeapon: Raygust.
* NiceGuy: 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.
* OvershadowedByAwesome: 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.
* TheScapegoat: [[spoiler: [[InvokedTrope Invoked]] but [[SubvertedTrope subverted]]. Eizo Netsuki ''tried'' to shift blame for the 32 C-class agents being kidnapped to Osamu, but because of [[SpannerInTheWorks 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]].
* SmartPeopleWearGlasses: One of the few people wearing glasses and definitely smart.
* SwordAndGun: 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.
* SpecsOfAwesome: He has his moments.
* TookALevelInBadass: He is definitely one of the characters who has the most catching up to do, so this is pretty common.
* WeakButSkilled: The major difference in Osamu's fighting style in comparison to [[TheAce Yuma]] and [[UnskilledButStrong 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 [[LampshadeHanging points out]] Osamu is weak but not stupid.

!!Yūma Kuga
-->[[AC:B-Class, Attacker]]
-->15 Years
-->'''Voiced by:''' Creator/TomoMuranaka

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

* TheAce: 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 [[spoiler: he manages to defeat [[BadassGrandpa 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 TheAce of Tamakoma-2.
* AdaptiveArmor: His Black Trigger.
* ArmedLegs: Can power up his legs with his black Trigger.
* AlmightyJanitor: 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.
* AmbiguouslyHuman: Looks like a human but is a humanoid neighbor in truth. The white hair and red eyes might give a hint.
* BadassAdorable: A rather cute looking young boy on the outside, an experienced and deadly soldier on the inside.
* BewareTheSillyOnes: 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.
* DarkIsNotEvil: His black armor when using his Trigger.
* DeathByOriginStory:[[spoiler: Got killed by a mysterious foe before the series began, though his father sacrificed himself to create a Black Trigger that keeps Yūma alive.]]
* DualWielding: Prefers using two Scorpions when not using his Black Trigger.
* HeroicAlbino: White hair, red eyes, definitely heroic.
* LivingLieDetector: His side-effect, inherited from his father due to his Black Trigger, lets him notice if someone lies.
* LivingOnBorrowedTime:[[spoiler: 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.]]
* MagicEnhancement: An ability of his Black Trigger. Can be used both on himself and other Trion-users.
* MemeticBadass: InUniverse. 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 CurbStomping Midorikawa 8-2.
* MorphWeapon: Both his black trigger and the Scorpion.
* OlderThanTheyLook: [[spoiler:Since his Trion-Body doesn't show signs of aging.]]
* PintSizedPowerhouse: Because his growth has stopped [[spoiler:since his death]]. Not a problem, since Trion-bodies don't rely on physical body mass anyway.
* PowerCopying: His Black Trigger can analyse and copy Triggers that are used against him.
* PowerFist: His standard attacks with the black trigger involve punching things with a powered fist.
* SkilledButNaive: While he is a very skilled individual, [[BlueAndOrangeMorality he has little knowledge on how Society works in our world.]]
* SpringJump: Picks up the Grasshopper after reaching B-Rank, which allows him to jump in midair.
* SwissArmyWeapon: Just look at all the abilities of his Black Trigger listed here...
* TrickBullet: 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.

-->[[AC:Tropoi Autonomous Trion Soldier]]
-->'''Voiced by:''' Creator/HideyukiTanaka

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

* HeroicSacrifice: [[spoiler: 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]].
* NonHumanSidekick: To Yūma Kuga. He acts as his guardian and also gives him certain powers.
* TheSmartGuy: 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 [[spoiler: a replica Rabbit after analyzing one of the original models]], and, with Osamu's help [[spoiler: is ultimately the one who forces the Aftokrator neighbours to retreat]].

!!Chika Amatori
-->[[AC:B-Class, Sniper]]
-->13 Years
-->'''Voiced by:''' Creator/NaoTamura

The younger sister of Osamu's tutor. He himself became her tutor, [[spoiler: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.

* BadassAdorable: She's the cutest little kid you could think of... and also able to fire an almost unstoppable DeathRay.
* BlessedWithSuck: 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, [[spoiler: her brother and friend both end up getting kidnapped trying to help her]], and during the Invasion Arc [[spoiler: she is turned into a Trion Cube and almost captured by the Humanoid Neighbours]]. Girls got it rough to say the least.
* TheCutie: A genuinely sweet kid with an oversized sniper rifle.
* DoesNotKnowHisOwnStrength: Even after joining Border and starting her Sniper training, she still doesn't know half the extent of her Trion prowess.
* DoomMagnet: Her enormous Trion attracts a lot of strong neighbors that try to capture her and are a danger to everyone around her. [[spoiler:She has become traumatized after her brother and her best friend were captured by Neighbors.]]
* FriendlySniper: For all her destructive potential she is the sweetest girl you could think of.
* IdiotHair: In the middle of her head.
* InSeriesNickname: 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 [[{{BFG}} Ibis]].
* LongRangeFighter: As a sniper she at least SHOULD be this, sadly she often finds herself to be rather close to the action.
* MemeticBadass: InUniverse along with the rest of her team. See the "Tamakoma's Trion Monster" thing above.
* PintSizedPowerhouse: Small stature, ridiculous amount of Trion.
* TaremeEyes: A trait shared by none in the manga.
* UnskilledButStrong: HUGE Trion-supply, but still an inexperienced trainee and not the best shot even among the new snipers.

!!Yūichi Jin
-->[[AC:S-Rank, Attacker]]
-->19 Years
-->'''Voiced by:''' Creator/YuuichiNakamura

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.

* TheAce: Never anything less than confident, being immensely skilled and able to see the future to some degree
* TheChessmaster: 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. [[spoiler: During the large scale invasion arc, the Aftokrator even note that ''someone'' was pulling the strings the entire time.]]
* CombatClairvoyance: His side-effect allows him to see the immediate future, which includes most incoming attacks.
* CoolShades: His signature accessories.
* GuileHero: 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.
* MorphWeapon: The Scorpion Trigger, which was created by himself.
* RazorWind: 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 [[SwordBeam extending energy blades]].
* SunglassesAtNight: Never seen without them, no matter the time of day.
* TrademarkFavoriteFood: 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.

!Neighborhood Worlds


-->24 Years
-->'''Voiced by:''' Creator/NozomuSasaki

* AchillesHeel: It's revealed that Hairein's trigger [[spoiler: 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 [[spoiler: once Osamu deactivates his Trigger meaning that Hairein's Trion animals [[NoSell have absolutely no effect on him]] and he's forced to attack Osamu directly making him vulnerable to Mira and Yuma's attacks]].
* AnimalMotifs: A Dragon, according to the Extra Material.
* TheBeastmaster: 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.
* BigBad: Of the Large-Scale Invasion Arc since he's the one whose leading the other Aftokrator Neighbours in [[spoiler: capturing the C-Rank members of Border]].
* CombatPragmatist: Not against using underhanded tricks like asking Moira for assistance and stabbing Kyosuke from the back with one of her portals.
* TheCaptain: Of his group.
* OhCrap: 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 [[spoiler: he realises Viza was defeated by Yuma]].
** Secondly when [[spoiler: Osamu deactivates his Trigger forcing Hairein to confront him directly]].
** Finally once he realizes that [[spoiler: that Osamu's true aim was his ship the entire time and he's forced to flee without capturing "The Golden Goose"]].
* PragmaticVillainy: 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.
* ReasonableAuthorityFigure: Towards his team, even asking for feedback from Lamvalein about his choices as a leader.
* ShootTheDangerousMinion: Decides to get rid of Enedora due to his violent personality.
* TheStoic: Always calm, even when things start going against his favor.
* StunGuns: 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.
* TechnicalPacifist: 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.
* YouGottaHaveBlueHair: In the anime.

-->24 Years
-->'''Voiced by:''' Junichi Yanagita

* ArmCannon: His Trigger "Chelidon".
* AnArmAndALeg: Loses his leg for being too confident of his incoming victory around Midorikawa.
* TheBrute: Averted. Looks like this because of his size, but hes actually a long range fighter with some honor inside.
* BeamSpam: 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.
* BoisterousBruiser: He enjoys fighting a lot and is an openly friendly guy.

* JetPack: A feature of his Trigger which allows him to fly and bomb his enemies.
* MorphWeapon: His Trigger, which can whip out various cannons at different parts of his body.
* MoreDakka: His main strategy in fights.
* NobleDemon: 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.
* ShoutingShooter: When Yoneya jumps over him to stab him with his spear, lets just say he lets out a long scream.

-->20 Years
-->'''Voiced by:''' Creator/ToshioFurukawa

* BloodKnight: Very interested in killing humans.
* TheBrute: Though he displays some intelligence, correctly figuring out how the members of Kazama unit are dodging his attack and how Suwa unit are tanking his attacks, he also displays huge arrogance, meaning he plays this role to his group.
* IShallTauntYou: 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.
* KilledOffForReal: [[spoiler: 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]].
* MorphWeapon: His Black Trigger "Vorvoros" can turn his entire body into liquid or gas.
* MismatchedEyes: A product of of his horns messing with his head.
* NighInvulnerability: 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.
* PersonOfMassDestruction: 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.
* SmugSnake: Very confident on his abilities, which in turn gets him killed.

-->16 Years
-->'''Voiced by:''' Creator/NobunagaShimazaki

* TheComicallySerious: After being stranded in earth where he has to interact with Tamakoma weirdness.
* ExtraOreDinary: His Trigger "Lampyris" makes him capable of controlling magnetism.
* InTheHood: Usually on his casual attire on earth.

* SempaiKohai: This seems to be basically his relationship with Hairein, where he is the Kohai and Hairein the Sempai.
* TranquilFury: His usual mood.
* UndyingLoyalty: To Aftokrator. Hairein was however sure he was going to betray them.
* WingedHumanoid: Can create metallic wings on himself and allies, though the flight actually works by being shot through a magnetic track like a railgun.

!!Moira (pronounced Mira)
-->23 Years
-->'''Voiced by:''' Yurie Kobori

* ArrangedMarriage: Either with Lamvalein or Hairein.
* BobHaircut
* TheDarkChick: Her dark clothes and mean but loyal personality seem to point at that.

* SexySecretary: Has the looks of it, and also acts as a
** MissionControl: To the rest of the group until she finally enters the battle herself.
* ThinkingUpPortals: Her Black Trigger can create portals, which can be used to retrieve allies. They can also be used as spikes to impale enemies.

-->65 Years
-->'''Voiced by:''' Hiroshi Naka

* AffablyEvil: Is easily the nicest guy amongst the Invading Neighbors, commenting that [[spoiler: kidnapping children doesn't sit right with him]] and congratulating Yuma [[spoiler: 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 [[spoiler: the fact that Yuma actually managed to defeat him causes the usually {{Stoic}} Moira and Hairein to have major OhCrap moments]].
* BadassGrandpa: [[http://i1.wp.com/www.populationgo.com/wp-content/uploads/2014/06/WT4.png 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.
* BewareTheNiceOnes: He is more gentle than most of his fellow countrymen, but also seems to have a darker side which he rarely shows.
* BladeSpam: His power.
* BloodKnight: A calmer and subdued variant in contrast to Enedora, but when defeated admits to never get enough of battles.
* CoolSword: His Trigger "Organon" is actually a sword hidden in a walking staff.
* EyesAlwaysShut: Always, without exception.
* GracefulLoser: [[spoiler: 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]].
* InstantDeathRadius: Pretty much how Organon works, creating circular blades that cut through everything on the area that surrounds him.
* MagicStaff: His Trigger might count, though it actually hides a sword. Can create energy blades everywhere around him.
* NiceJobFixingItVillain: Lying to Yuuma was his greatest mistake.
