She is a aged woman wearing glasses and the typical black monastic habit with a headdress and a cross pendant. She has a mole on the forehead which is hidden by the headdress.
The Mother is a very kind woman having dedicated his life to the orphan children. She is a reassuring, making sure Timothy doesn't worry about his peculiar forehead. When she was caught by the akuma power she immediately and selflessly told the others to run away.
She has held the orphenage for a long time.At some point the orphenage started to have money issues which threatened to close it, she was very worried about what would happen to the children. When Galmar entrusted her with Timothy she took him to a doctor to examine his strange forhead. The doctor explained there is no way to remove the crystal she told Timothy that as long as it doesn't prevent him from washing his face there is no problem.
Reverend Mother reveived a gift letter (from G) before the exorcists arrive. She welcomed them and informed them about Timothy's past. Then Kanda stated that they would take Timothy to the Order to what she replied they can't force him to go. At this moment, the orphenage is sent to the dimension created by the skulls and the level 4 attacks. She wonders if the level 4 is an angel to the negation of the akuma. She takes the children and tries to take refuge downstairs but she is made into a doll by the power of a level 2 akuma. LAter the akuma is defeated and she returns to normal.
After the battle she awakes besides Timothy and the other children and assures them she is fine. She is later seen in a garden with Timothy. They talk about their future separation with tears of emotion. Mother would temporarily move to London and stay with Father Frederico.
