End slate
From VNDev Wiki
An end slate is special image at the end of a game's route, usually representative of the route's ending mood or the route’s overall theme. The image is usually shown after all of the route's text has finished and often is accompanied by the name of the ending. Typically, these images are completely unique (not recycled assets) and not CGs but more simple/iconic or chibi. Games that feature end slates: Hatoful Boyfriend, Long Live the Queen
