Description
She is good at math but a little forgetful. Her favorite saying is, "Did I say that?" But she doesn't mind too much because she can ask the marshmallow mouse boy and he will tell her everything she needs to know. Like the boy, he is also a hard worker and is good at comforting Mitsugo-chan. Name: Katherine Marshmallow Birthday: May 28 / Hobbies/Skills: Mental arithmetic
