A member of the Victorian Housekeeping faction, a human resource dispatch agency with a wide range of services, Ellen does a variety of odd-jobs. They can range anywhere from Hollow exploration to protection of VIPs, and even working at a maid cafe.
Ellen herself does not like taking on commissions that she deems annoying, and is otherwise rather apathetic about most anything. Even in school, she has declined joining almost every club that has approached her for recruitment. She would much rather just live her life as simply and normally as she can.
When on the job, Ellen wears her usual maid uniform, and wields a pair of shears in combat.
