ヴァイオレット・エヴァーガーデン きっと"愛"を知る日が来るのだろう

Violet Evergarden, working as an Auto Memory Doll who ghostwrites letters for others, takes on an assignment from opera singer Irma Felice. Irma wants a love letter powerful enough to be sung on stage, but she gives Violet almost nothing to work with and turns down draft after draft. This standalone OVA is set between episodes four and five of the main series.
