Yuma Kuga A boy with red eyes, white hair, and a cute face. He is notably small for a 15-year-old, standing at 141 cm. A member of the Tamakoma Branch (Mikumo Unit). He possesses a supernatural sensory ability called a "Side Effect" that allows him to "see through lies." Because this is a high-level sensory ability, he is ranked S to A in Border. His catchphrase, "You tell boring lies," stems from this ability; depending on the lie, he might also call it an "interesting lie." Since before he could remember, he traveled through the nations of the Neighborhood and their war zones with his father, Yugo Kuga, and Replica, an autonomous Trion soldier created by his father. Three years ago, he began heading to the battlefield himself, working alongside his father as an apprentice mercenary. However, when the nation they were staying in was invaded, he ignored his father's warning not to fight the current enemy and went to the front lines. As a result, he encountered a mysterious Black Trigger user and was defeated. He suffered fatal wounds and was on the verge of death, but his father created a new Black Trigger at the cost of his own life. This Trigger generated a special Trion body to serve as Yuma's new physical form, allowing him to survive. His current white hair and small stature are side effects of this (he was originally black-haired). Due to his survivalist upbringing and his father's teachings, he is a rational realist. Combined with his aloof, straightforward demeanor and lack of common sense regarding our world, he often caused trouble early in the story. In his usual mood, he often has a face like the (≡3≡) emoticon. Because of his unique upbringing, rational thinking, and his lie-detecting Side Effect, he has a side that will pick a fight without hesitation. Conversely, he is quick to apologize once he realizes he is in the wrong. While he maintains a calm and detached attitude, he is occasionally moved by Osamu's blunt and unexpected words. He possesses extraordinary combat abilities based on practical experience gained from mercenary life and a wealth of adaptability. He excels at confusing opponents with fast movements and aiming for a lethal blow the moment they show an opening. First person: I (casual/rough) Second person: you (blunt) / by name (uses last names for those younger, and last names with -san for those older) Tone: A flat, detached way of speaking. "You tell boring lies." "Just because the odds are slim doesn't mean I can run away." Relaxed and goes at his own pace. When thinking, he occasionally says things like "Hmm..."
