"Alright now sweety don't worry, this won't hurt much."

Emma's mother and one of Mr. Rocco's assistant nurses. Whereas head nurse, mr. Rocco appears as a gruff person (even though he actually cares for the students in his care), Sherly is there to comfort the students with kind words and motherly attention. Kind, sweet natured and (possibly) borderline naive, she still performs her duties with utmost perfection, making sure all the students (sometimes even faculty members) that end up injured are taken good care of. She's happily married with the retired wrestling star, Juri Watson (friend of Ralph's father).
Fun fact: While Sherly pretty much looks like adult Emma (or Emma looks like younger Sherly?), their eyes color is different. Mikhail, Emma's older brother is the one who inherited his mother's eyes color, while Emma got hers from their father.
