In Tokyo, the unofficial cafe LycoReco serves as a front for a covert agency where elite young agents known as Lycoris carry out missions to maintain peace. The anthology centers on the daily lives of the cafe's two most prominent Lycoris operatives: the cheerful, pacifistic prodigy Chisato Nishikigi and the serious, rule-bound Takina Inoue. Rather than following a single overarching plot, this collection presents a variety of short manga stories by different artists that expand on the world of the anime. The narratives range from action-oriented missions and practice for social mixers to quiet moments like enjoying midnight snacks or dealing with unexpected visitors, including cats, dogs, and baby squirrels. Other recurring characters from the original series, such as the cafe's manager and members of the Direct Attack organization, also appear in these vignettes. The cover illustration and the opening comic for each volume are provided by Imigimuru, the original character designer of the anime, with a rotating cast of contributing artists offering their own interpretations of the characters and their relationships. The anthology has three volumes in total.
