Seven Shots

It is a handgun used by both BRSB and Nana Gray. As the name implies, it fires 7 shots per round. It's usage are pretty much, like how one uses a handgun.

This is BRSB's secondary weapon and Gray's secondary weapon as well, as both characters are more inclined to using close-range weapons ( BRSB utilizes BRSBlade and Nana uses an unnamed sword-like weapon).
