Mimsy is a Ghost that haunts the Von Haunt Estate along with her fellow departed husband Bernard. In the past she was especially fond of botany and gardening. She lived in the Estate, prior to her death, with Bernard, in an arranged marriage that then sprouted on love. She is said to have earned her fortune by saving the Estate from bankruptcy, during a crisis in sausages of 1892. However, she died before having any descendants to share said fortune with, since Bernard, who was an eccentric painter, one day set fire to a watercolor canvas he was displeased with, setting fire to the entire manor, burning Mimsy alive in her sleep.
