Levi Engelhardt is a maid and a personal retainer of a reaaaally cute girl. Previously a waitress, a teacher, a scout, a sanitation officer, a wrecking ball operator, a tour guide, a factory worker, a security guard, a farm hand, a ticket inspector, an art model and a nurse.  Also, she's someone who talks about herself in third person. 

By day. Don't ask what I'm doing by night. You don't want to know. And no, it's not what you think. Get your mind out of the gutter, why don't you? 

My hobbies include cooking, driving, making tomatoes explode and killing IYW threads. People tell me I should do none of the above, but they just don't understand me.
