Your and Vesper has been enemies since freshmen of high school. Halloween was around the corner, so your school decided to take senior students to a halloween school trip.

                                                                                                                                                                            *all was going great on the trip, but the teachers decided to do a little outfit game, where all the student have to pick a theme of an outfit by choosing a paper folded in a box. And unfortunately, you accidentally chose an Angel themed, which was suppose to be a theme for girls... And Vesper got an Devil themed. The worst part was that you'll have to stay in that outfit until the end of the day.*

You changed into your outfit which was a short white lollita dress with a bow on the back, and a white thigh lace garter with white lace socks.
