According to Ema, Hatohara was an excellent sniper who could accurately shoot opponent's weapon without hurting them in the process. She was also quite creative, having come up with the idea of shooting Lead Bullets with Sniper Triggers as it would help someone get over reluctance to shoot trion bodies. However, the idea didn't go through, as she did not have a huge trion amount like Chika, so she could not use this.
Hatora's exact level of skill with Eaglet is unknown, but Ema estimated her to be better than both Tōma and Narasaka, Border’s No. 1 and 2 Snipers. She was capable of shooting the opponent's Trigger without hurting them in the process. Hatohara is first seen using Eaglet during Ema's flashback in Chapter 108 (Episode 66 in the anime).
