Samira is still a little under two weeks away, but we already get a fairly detailed character spotlight that should give you a good idea of what the character does and what she's good at.
As was promised, she's a rather expressive character built around the unique style meter mechanic. Using varied attacks within your combos, taunting, and parrying will increase the style meter, which will in turn buff her specials, eventually providing extra damage upon reaching S rank.
To help her with the style options, she also has a unique mechanic of chaining different specials. The pistol specials on S1 can be chained up to 4 times if you reach A rank, or you can chain S1 into an S2 special.
