Masataka Ninomiya/Abilities

Ninomiya is highly skilled in shooting and fighting in general, as is testified by him being the No. 1 Shooter and No. 2 overall combatant in Border, as well as the captain of the B-Rank #1 (formerly A-Rank) unit. His proficiency extends to strategy as well, making him a capable leader. In rank wars, he generally fights on his own, as his individual power is great enough to crush most opponents. He was able to single-handedly defeat Kuga, a fighter on par with some A-Class agents. According to Kazuma Satomi, Ninomiya is the absolute strongest in one-on-one combat, although by his own admission his statement is biased. Nonetheless, he told Osamu that the only person who could stand up to him in a straight shoot-out used to be Kōhei Izumi, under whom Ninomiya further polished his skills as a Shooter after becoming the No. 1 Shooter.

Thanks to his exceptionally high amount of trion, Ninomiya boasts tremendous offensive and defensive abilities which allow him to grind down any opponent he encounters in an open field. As a Shooter, Ninomiya adopts a unique fighting style wherein he goes into Full Attack and divides his two trion cubes differently, centering one on numbers and the other on power: if the opponent defends against the numerous, smaller bullets with a wide Shield, the larger bullets will break through it, but if they focus it to block the larger bullets, they will be unable to stop the more scattered and numerous small ones. The effectiveness of this combo is such that for most Border agents it is impossible to counter even if they know about it, with the general consensus being that once one becomes Ninomiya's targets, they are as good as defeated.

Aside from his trion reserves, what makes this fighting style so terrifying is Ninomiya's skill at manipulating trion bullets. Although summoning, splitting and aiming trion cubes normally takes time, Ninomiya can do so at extreme speed, so much so that he has demonstrated the ability to execute these passages so quickly that no trion cube appeared to have been created at all, catching even the extremely fast Kuga by surprise. Only a handful of extremely quick fighters may be able to defeat Ninomiya by getting the draw on him, provided they can get close enough. He is the only Shooter who was shown capable of manifesting trion cubes without needing to use his hands, which he keeps inside his pockets. He is able to create composite bullets rather quickly, or at least fast enough not to need to take cover while merging trion cubes.

Despite the effectiveness of his Full Attack combo, Ninomiya never used it in his first match against Tamakoma Second. This might have been a precaution against the number of foes, especially hidden Snipers, so as to be able to rapidly switch to defense.

Trion
Ninomiya had the greatest trion capacity in all of Border prior to Chika's enlistment. This grants him above-average offensive and defensive abilities, making him extreely difficult for Normal Trigger users to defeat in one on one combat. His large trion amount also allows him to continue firing until his opponent's defenses are whittled down without worrying about his stamina.
