As stated by Queen Victoria, Derek is a fifth year student at Weston College who had consecutively sent letters home every day. However since last summer vacation, he has refused to return home. Derek is firmly resolved with that decision, even after his mother contacted the dormitory.
Derek is one of the few students at Weston College who are refusing to come home, causing his father's depression and Queen Victoria to worry about their wellbeing. Thus, she sends Ciel Phantomhive to investigate the matter as she wishes for everyone close to her to be able to be carefree this Easter season as well.
During the Midnight Tea Party, Ciel confronts the principal and the P4 about Derek. After proposing to call the Scotland Yard, Johan, the Vice Principal of Weston College, announces that it will not be necessary. A smiling Derek then steps out of a door in the back of the room, announcing it smells of tea.
