Rei Nasu/Abilities

Nasu is a Master Class Shooter who manages to be the ace of her squad despite users of Gunner Triggers generally acting as support. This is in no small part thanks to her ability to program trajectories for Viper in real time, which only she, Kōhei Izumi, and Hyuse are capable of in all of Border. In the match against Tamakoma Second and Suzunari First she was able to withstand the combined assault of Osamu Mikumo, Tatsuya Kuruma and Taichi Betsuyaku and eventually overpower them, albeit at the cost of her own defeat, while also remaining on the look-out for Chika Amatori's sniping. Hyuse thought her capable of taking out her four opponents on her own, although Jun Arashiyama reckoned that she would not be able to best Yūma Kuga or Kō Murakami on her own due to the high performance rate of Shield. With Yūko Kumagai's assistance and a pointer from Shirō Kikuchihara, Nasu managed to force Wen Sō, who was noted to be A-rank level or above, to bail out.

Nasu is rather accurate as a Shooter, hitting multiple small targets with a single activation of Viper. She displayed some skill at scattering and controlling Trion cubes by fashioning her ammunition into one or two rings which float around her person. Her arsenal has been recently expanded to include composite bullets. Her usual fighting style consists in using the environment as cover while cornering the opponent with her remarkable mobility. She is capable of running on walls and leaping from the side of one building to the next without slowing down, making herself a difficult target to hit for a single opponent. Her quick reactions make her even harder to catch, so much so that, despite her being pressured on two sides and him being stationed behind her, Osamu could not force her to raise a Shield until he reprogrammed his Asteroid. Her reflexes are what enabled her to survive Wen Sō's attack after the latter disguised herself as Kumagai. When the circumstances call for it Nasu can switch from tactical maneuvering to shooting from a stationary position in order to control the movements of multiple enemies and lure Snipers into revealing themselves. She is also skilled at coordinating with Kumagai, who defends her while she goes into Full Attack. Her experience allows her to anticipate the moves of less skilled opponents, and she has proven herself capable of strategizing in the middle of combat, although her strategic ability was deemed lower than Osamu's by Kei Tachikawa. Yūichi Jin observed that this shortcoming is due to the strain caused by being both the captain and the ace of her squad.
