YSSM means Yumi Saburo Sachiko Makoto or Cherry Saburo Sachiko Makoto. These are 2 of my 4 role playing characters. I shall explain Cherry and Yumi. Cherry is a happy/exciting person, she might be dumb fighting, but what she does is that she plays with her enemies and gets their information like what they use, are they far distance, and what the best way to defeat them. Yumi is a serious person, she never laughs or smiles, she likes to make everything alot easier and everything. Yumi and Cherry use the same body, because they do xD. Don't be so sure that you can always defeat them ^^.
