This is Yuki's sister from my manga idea (still thinkin' on a name >_<. I tried to make her look like she's got at least a little bit more personality than her sister does (who has virtually none whatsoever). The other half of the two-woman assassin team, also former Navy SEAL member.
She uses a H&K USP .45 tactical as her sidearm, and primarily she's using a SIG 550 Sniper automatic sniper rifle. In other words, contrary to her sisters "one shot, one kill" mentality with her Arctic Warfare, she prefers to make sure the target is dead, and can actually wound people instead of killing them in one shot like her sister. She's a little more liberal with her shooting though, and does like to expand ammunition a lot
