Kuga, Yuuma

空閑遊真

Yuuma Kuga is a main protagonist of World Trigger and a Neighbor possessing a high Trion level and Trigger Skills.
Yuuma is very short for his age. He has white hair and red eyes. He wears a blue suit top and gray bottoms, which are traditional for Japanese high school students. When not in Trigger mode or his school uniform, he usually wears a black hoodie featuring a paw symbol and the text "UMA" (which stands for "Unidentified Mysterious Animal"), along with baggy jeans.
In Black Trigger mode, Yuuma gains a black jumpsuit that his Replica fuses with. In C-Class trigger mode, unlike most other trainees, he gains an all-black uniform instead of the classical all-white one; it features a black jacket with thick white stripes running from the sides of his collar to the sides of his sleeves and also around his collar, as well as thin gray stripes on the borders of the zip fastener and collar.
In B-Class trigger mode, he wears a uniform similar to Osamu's, except his jacket's left sleeve lacks a shoulder guard. His right arm also has the same design as his left, unlike Osamu's, making his jacket more symmetrical. Additionally, the black stripes on his jacket's sleeves are thinner and, unlike Osamu's, do not have white stripes in their middle, and the black stripes also extend over his shoulders and collar. On the sides of his shoulders, he has the Tamakoma Branch emblem, surrounded by the stripes. Furthermore, the sleeves of his jacket somewhat merge with his gloves, and he tucks his pants inside his boots, as he did when he was a C-Class agent. His Unit's emblem is located on his left chest.
Yuuma has a laid-back personality and is not very knowledgeable about Japanese customs, due to being from another world (despite having a Japanese father), leading to some run-ins with rough people. He is logical, advising Mikumo to stay away from the Trion Battle Soldier rather than save the students, as Mikumo could die. He seems to be aligned with Border's cause, fighting against Neighbor forces. Despite his happy exterior, he is actually deeply depressed due to his father's sacrifice to revive him, and had no more reason to live other than bringing him back to life.
