The article is a list of characters that appear in the action sci-fi manga and anime World Trigger by Daisuke Ashihara.
A humanoid Neighbor from the Neighborhood, who is laid-back and unknowledgeable of Japanese customs.[citation needed] When he was 11 years old, he and his father Yūgo Kuga (空閑 有吾, Kuga Yūgo) were involved in a war in the Neighborhood and lent their power to Raymond, an old friend of Yūgo's.[citation needed] Yūma disobeyed Yūgo, who had told him not to follow him, by sneaking into battle, causing him to be severely injured.[citation needed] Yūgo sacrificed himself to create a Black Trigger (黒 トリガー, Burakku Torigā) to prolong Yūma's life,[citation needed] sealing his dying body in a ring that also holds the Black Trigger.[citation needed] His guardian, Replica, told him to go to the human world to see if Border could find a cure for his condition; however, he wants to bring Yūgo back by removing the Black Trigger from his body, even though it is keeping him alive. .[citation needed] In chapter 33, he officially joins Border as a C-Rank attacker in Tamakoma-2.[citation needed] In the anime, he is known as the "C-Rank White Devil" (C級の白い悪魔, C-kyū no Shiroi Akuma)[citation needed], and the Kōda Squad calls him the "White Nightmare" because of his white hair and ferocity in battle.[citation needed] In Season 2, Ōji gives him the nickname of "Cougar".[citation needed] He is a Speed Based Attacker that uses Scorpion to fight in Rank Wars.[citation needed] After receiving the Black Trigger, he inherited a Side Effect which enables him to determine when a person is lying.[citation needed]
A 15-year-old boy and a Border agent with low Trion level, who befriends Yūma after he transfers to his school and rescues him from a Neighbor attack. He is later promoted into B-Rank Border and becomes 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 is usually referred as "Four Eyes" by those outside Tamakoma-2. He becomes Chika's protector after her older brother and his tutor mysteriously disappeared and joins Border to be better able to protect her, but the examiner instead suggests that he become an Engineer or Operator due to his low Trion. Unable to accept this, he tries to infiltrate Border's headquarters and negotiate with them, but after Jin saves him from a Bamster, he convinces Border to accept Osamu as a C-Rank trainee.
A 14-year-old girl with abnormally high Trion levels, which "attracts" Trion Soldiers towards her, and who joined Border as a C-Rank Sniper in Tamakoma-2 seeking to save her brother Rinji and her friend after Neighbors captured them. She purposely distances herself from others out of fear that those close to her will be hurt. She has two side effects, one that allows her to sense the presence of approaching enemies, and one that hides her presence. Izumi refers to her as "Tamakoma's Trion Monster" (玉狛のトリオン怪獣, Tamakoma no Torion Monsutā), due to her huge amount of Trion, andin Season 2, she becomes known as "Tamakoma's Cannon".
A 19-year-old man and an A-Rank Solo Attacker, who was originally S-Rank, at Border who possesses the ability to see the future as a result of his Side Effect. He is a self-proclaimed "Talented Elite", and is skilled at formulating strategies in battle. Although his mother was killed by the Neighbors, he does not hate them because he has been to the Neighbor World and knows that they are not all evil. He invited Yūma to join Border, and like Yūgo, his mentor Sōichi Mogami (最上 宗一, Mogami Sōichi) sacrificed himself to create a Black Trigger, which Yūichi competed for, and later gave it away so Yūma could officially join Border and Headquarters could recognize him as a Border agent.
Yūma's guardian, whom Yūgo created to protect and teach him and has information about the countries he and Yūma visited. They told Yūma to go to the human world to see if Border could find a cure for his condition. After telling Osamu Yūma's story, they ask him to give him a new goal. Near the end of Aftokrator's invasion, Replica is severely damaged and Osamu throws them into Aftokrator's away ship and activates the emergency launch command. While this saves Osamu and Chika, Replica is unable to escape the ship. It is currently unknown if they survived.[5]
