As the No. 3 Attacker, Konami is shown to be an extremely powerful individual. In her first fight with Yūma, she was able to defeat him in 9 rounds out of 10, and even later on, he was never able to get more than 3 wins against her. The current difference in strength between them was estimated to match that between Shinoda and Tachikawa.[BBF Q126] She is said to be strong enough to be considered the equivalent of one unit by herself, and in fact, for the purposes of defense missions, she is considered the equivalent of one unit.[BBF Q218]
Her fighting style ignores trion performance to focus on pure firepower. Her movements are similar to the way a Neighbor fights. Konami is also very fast and agile, easily dodging two Rabbits' attacks and defeating them with little effort. By quickly switching Triggers, she can fight at different ranges and change the speed and power of her attacks. Gatlin commended her offensive abilities and mobility in their fight. His admiration later increased when he learned she was able to strike Vasilissa in the exact same place Tachikawa had already damaged. She is also rather perceptive, understanding that Yūma was the strongest member of what would become his unit just by looking at him, and managing to sense the threat of Organon before knowing it was a Black Trigger, which earned her Viza's praise. Notably, she was uninjured after both the invasion of Aftokrator and the blitz of Galopoula, despite never using any defensive Triggers.
One of Kirie's personal Triggers is Sōgetsu, a knife with a curved blade. It is powerful enough to nick the armor of a Rabbit. She always uses two at the same time, unless to switch briefly to Meteora. It is a Trigger exclusive to the Tamakoma Branch. Konami is shown to be very skilled at using them, taking full advantage of her agility. In the manga, she was first seen using it in chapter 53, although in the anime she was shown using it as soon as in episode 12.
Kirie, despite being an Attacker, can use Meteora. She is capable of using it in conjunction with Sōgetsu, first engaging in close combat to seal the opponent's movements, then retreating quickly and firing Meteora at close or mid-range. She is able to scatter the bullets to a certain extent, as well as target two opponents at the same time. Her Meteora was considered very dangerous by Gatlin, and in fact it can crack the durable armor of Rabbits. She was first seen using it in chapter 55 (episode 25 in the anime).
The Connector is a Tamakoma branch-exclusive Trigger which can be used to merge two Sōgetsu to create a powerful axe. Like Senkū, it can (and must) be activated while two Sōgetsu are in use. She was first seen using it in chapter 55 (episode 25 in the anime).
By placing the tips of Sōgetsu's handles together and using Connector, Sōgetsu becomes a giant battle axe. Despite its big size, Konami can swing it with ease, chaining fast and powerful attacks. Unlike Border's normal Triggers, which are intended for many people to use, Konami's special Triggers focus on "firepower", making them much more destructive in return for an increased trion expense. She was first seen using the axe in chapter 55 (episode 25 in the anime).
