List of World Trigger characters

The article is a list of characters that appear in the action sci-fi manga and anime, World Trigger.

Main characters

Yūma Kuga (空閑 遊真, Kuga Yūma)

Voiced by: Junko Minagawa (vomic), Tomo Muranaka (anime) (Japanese); Cathy Weseluck (English)

Coming from the Neighbor World, he has a laid back attitude, and isn't very knowledgeable of Japanese customs, leading him into confusions with the wrong people. When he was 11, he and his father Yūgo Kuga (空閑 有吾, Kuga Yūgo) were in a war in the Neighbor world/Neighborhood, lending their power to an old friend of his father. In an occasion where his father told him not to follow him, Yūma disobeyed his father, sneaking into battle, which caused his death. His father, finding his dying son, sacrificed his life to create a Black Trigger (黒(ブラック)トリガー, Burakku Torigā) to prolong Yūma's life. Yuma's dying body is sealed in a ring that also holds his black trigger and he received a body made from Trion. His guardian, Replica, told him to go to the human world and see if Border could find a cure to his condition (though he wanted to bring his father back instead), only to find out they didn't know the answer either. In chapter 33 he officially joined Border as a C-Rank attacker in Tamakoma-2. As he explained, he's what they actually call a "Neighbor", and the creatures that have been attacking the human world are actually "Trion Soldiers", drones created to perform different tasks. He received the nickname "C-Rank White Devil" (C級の白い悪魔, C-kyū no Shiroi Akuma) in the anime, and gets called "White Nightmare" by Kōda Squad, due to his white hair and ferocity in battle. In Season 2, he gets the nickname of "Cougar". Despite his young appearance, he is 15 years old. He is an Attacker that uses Scorpion to fight in the Rank Wars. He inherited a Side Effect which enables him to accurately determine when a person is lying after getting his black trigger.

Osamu Mikumo (三雲 修, Mikumo Osamu)

Voiced by: Ryōta Ōsaka (vomic), Yūki Kaji (anime) (Japanese); Brian Doe (English)

A Border agent with low Trion level. He is usually referred as simply "Four Eyes" by people outside Tamakoma-2. He later promoted into B-Rank Border and later became a Shooter and the leader of Tamakoma-2 (玉狛第二, Tamakoma Dai-ni), also known as Mikumo Squad (三雲隊, Mikumo-tai). He became Chika's protector after her older brother (and his tutor) disappeared mysteriously, and joined Border in order to be better able to protect her, but the examiner suggested him to become an Engineer or Operator, due to his low Trion. Unable to accept this, he imprudently tried to infiltrate Border's headquarters and negotiate with them, but he was attacked by a Bamster, which was destroyed by Jin. The S-rank member then talks Border into accepting Osamu as a C-Rank trainee. He befriended Yūma after he was transferred to his school. He is 15 years old.

Chika Amatori (雨取 千佳, Amatori Chika)

Voiced by: Nao Tamura (anime) (Japanese); Caitlyn Bairstow (English)

A girl with abnormally high Trion level, which "attracts" Trion Soldiers towards her. Her brother Rinji and friend were captured by Neighbors, and tired of running away and looking for a way to rescue them, she joins Border as a C-Rank Sniper in Tamakoma-2. She purposely keeps herself away from others because she is afraid she'll cause them to be captured by Neighbors and she doesn't want to get hurt. She also has two side effects, one that allows her to feel the presence of incoming enemies, and one to hide her presence. Izumi labeled her as "Tamakoma's Trion Monster" (玉狛のトリオン怪獣 (モンスター), Tamakoma no Torion Monsutā), due to her huge amount of Trion. In Season 2, she becomes known as "Tamakoma's Cannon". She has short hair styled in a hime cut, with a cowlick in the middle. She is currently 14 years old.

Yūichi is an A-Rank Solo Attacker (originally S-Rank) at Border with precognitive powers. He is a very friendly and carefree person. He is a self-proclaimed "Talented Elite", but his skills and strategies in battle are more than enough to back up his confidence. His mother was killed by Neighbors but despite that, he doesn't hate Neighbors, as he has been to the Neighbor World and knows not all Neighbors are evil. He was the one who invited Yūma to join Border. Like Yūma's father, his mentor Sōichi Mogami (最上 宗一, Mogami Sōichi) sacrificed his own life to create a Black Trigger, which Yūichi competed for, and later gave it away so that Yūma could officially join and be recognized as a Border agent by Headquarters. His Side Effect allows him to see the future, which is highly valued by Border. He is 19 years old.

They was the one who told Yūma to come to the human world. Replica told Osamu Yūma's story, and asked him to give Yūma a new goal. Near the end of the large scale invasion by Aftokrator, Replica was severely damaged. While in this state Osamu throws Replica into Aftokrator's away ship, and activates the emergency launch command.
