Librarian

She offers her help to find a good picture book for Johan's friend. She is very clumsy, so while she's trying to find a book, many picture books fall off the shelves. Johan gives her one of his creepy and dreamy looks while helping her gather them. After that, he finds The Nameless Monster and collapses and the woman calls for help. She is later seen bringing flowers to the hospital, but Johan had already left. She meets Lotte Frank and tells her what happened. It is strongly implied that she has a crush on Johan.
