Overview
Dorei-san name comes from the word "Dorei" (奴隷, "Slave"). She thinks that she is just a thing. Therefore, if her master tries to treat her as a normal person by dressing her up or giving her normal food, she thinks she will be sold.
She has a very stoic and cold personality.
Controversy
Dorei's "joke" is being the only dark-skinned maid. Overseas (especially westerns) found the charater in poor taste due to the racist content.
Due to the offensive background of her character she has been grouped in with the Inappropriate Maids along with Yakui-san and Shitai-san.
