As he has been fighting in the neighbour wars for years, he has a great amount of experience and his combat skills put him in upper A class.

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. Yūma's trion organ seems to be black which can be a direct effect of using a Black Trigger.

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 ignore most attacks. He was hit by a car and was unscathed.

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.
