Ram

Ram is one of the twin maids working for Roswaal L Mathers. She is seemingly self centered and does things at her own pace, however, in actuality she maintains a distance from people to ascertain them. She believes that Roswaal is the greatest and no one else is as precious, except for her sister Rem.
