Yūma Kuga/Abilities

Yūma is a upper-tier B-Rank Border agent. He was part of Calvaria's army alongside his father when he was still in the Neighborhood, and through unfortunate events he attained a Black Trigger, greatly increasing his combat abilities. As he has been fighting in the Neighbor wars for years, he has a great amount of experience and his combat skills would put him in upper A class.

Physical Abilities
As someone who has battled from an early age, Yuma is very strong and agile despite his size, being able to fight on par with A-Class Border agents such as Miwa Unit.

Trion
High Trion level: Yūma has a Trion level higher than Osamu, making him much stronger and better with even Osamu's weak practice trigger and his own practice Scorpion. Trion Body: Yūma is always in His Trion body due to his real body being sealed in his ring to prevent his death. Being always in Trion form gives Yūma enhanced physical abilities, allowing him to perform many superhuman feats. It also gives him superhuman durability, allowing him to receive most physical attacks with little to no damage, once being hit by a car and emerging nearly-unscathed, with his body quickly recovering. It also makes it so he never needs to sleep.

Side Effect
Lie Detector: After gaining a Black Trigger from his Father, Yūma also gained his father's Side Effect of being able to distinguish lies from truth. In the anime, when he uses this ability, his pupils become black.
