Chief Maid

Demon Queen's most trusted servant and commander of her army. She usually does not refrain from expressing her point of view even before her master. Despite making unflattering comments to her master, she remains loyal to her master ever since they were children. Like her master, she also comes from the same demon clan that resides in the Outer Library but instead learning about economics, she learns the "Ways of the Maid" from peculiar sources. She can summon Ghost Maids (ゴースト軍団, Meido Gundan, lit. Ghost Maid Corps) to guard the mansion and serve the guests with her.
