She's a former fashion lifestyle vegan blogger.  She doesn't carry any weapon except her sturdy swiss army knife. Her survival asset is her huge mountain backpack full of canned food. Dolma is her nickname, she chose it after she tasted some canned stuffed vine leaves in an abandoned casher grocery the day the zombies took over the world. 
Since a zombie dog ate her iphone 8, she can no longer instagram her food. But she has found a new meaning of life : she allows her hair to grow, and starts a new fashion. You know, zombies are definitely not going to become vegan anyway.
