Lilith ("the Cockblocker") Reiner had lived always in a middle-class family. To support her family, she got a job at the Roux mansion at age sixteen. Now eighteen, she is one of two female maids there, and one Alexandrine's personal servants. She tends to every need of Alexandrine, dressing her, ironing her clothes, cleaning her room, and helping her bathe.

Lilith has long, curly black hair, which reaches past her shoulders. She has pale skin and brown eyes. She is often quiet, straight forward, and obedient. She rarely gets scared, angry or embarrassed. Due to her being a servant for so long, being close to guys hardly fazes her.
