Teruya fights together with her captain, combining their firepower. Izumi believes that the two of them together to be stronger than Katori Unit as a whole in a long-ranged fight.[1] Kakizaki deems her skills to be much higher than Border's rating suggests.[2] As an All-Rounder, Teruya has a flexible fighting style. She appears to be rather talented, as one month after enlistening, she was one of the three recruits with the highest score, the other two being the current No. 2 Sniper Narasaka and Utagawa, another A-rank agent.[3] She seems to have the best reaction time in her unit, since she was the only one on her team to dodge Yūma's attack completely.[4] Furthermore, she was capable of dodging multiple black Lightning shots[5] and intercept one at very close range.[6]

Although Kakizaki is generally in charge of strategies, Teruya is perceptive and quick to adjust to shifts in the tides of battle. She understood the necessity to split up in order to take out Chika.[7] She also managed to come up with a way to counter her Lead Bullet sniping minutes after seeing it in action for the first time.[6] Her ability to slip through Chika's attacks forced her to reveal another trump card,[8] and despite being immobilized, she managed to eliminate her target.[9]
