Sasha is a reoccurring character in the story and has already had a major part in volume 1. As indicated in the description, I'm not entirely familiar with the story so I'm not sure what her background is. I know that she's a soldier in training that was chosen to be amongst the top individuals that are dependable in combat. She's known for her laid-back attitude towards life, but can get serious when thinks start to get dire. She's also known for her love of food. First appears in chapter 7 in this volume.
