Sister May is the nun on duty at the Rolent branch of the Septian Church.
Unlike Father Divine, who has been in Rolent for decades, she's rather new to the city, being a recent transfer from Grancel. She's set to start teaching Sunday school to the younger children of the city. Her first lesson goes rather well thanks to Father Divine's advice, although she mentions having trouble dealing with Luke's naughty behavior. Nevertheless, she has managed to inspire enthusiasm in her pupils and some of them have even looked her up on other days of the week.
