She looks like a discount STAR-chan, although it's hard to describe anything that uses a stupidly expensive round like the 5.7 as a discount anything. She has a three second long cooldown and the skill lasts for two seconds. Her big thing is that she can also buff SMGs. She can be used either a mild firepower buff or an actually not awful evasion buff, the downside of which being that getting her evasion buff to work requires moving your dolls around.
