Eliminating the rebels

Aoi held her 2 pistols each with silencers and stood behind Tsubaki who planned to blow open the back of the tent with a widespread shot.

"Ready?" Tsubaki had pressed a different button on her flintlock which partly shrunk the barrel and Aoi, having a better look, was amazed by the technology. 

'She can't be related to Echo, so that only leaves the lower assassin branch which is more technology-based.' Aoi was slowly figuring out where Tsubaki came from as the kind of advanced weapon technology research has gotten popular among the lower assassin families. Aoi also dabbled in this, but her family were very traditional so she was only able to use her free time and resources to explore this.
