Peaceful days --- but there is a reason behind this.
The DA is a secret organization that prevents crimes before they happen.
Lycoris girls are its agents. Thanks to them, people can enjoy an ordinary, everyday life.
Nishikigi Chisato is an elite member who is known as the strongest Lycoris of all time.
The coffee shop LycoReco, where the talented but mysterious Lycoris Inoue Takina works, is one of their branches.
The orders it receives range from orders for coffee and sweets to taking care of children, doing shopping errands for others, and teaching Japanese to foreigners - things that are not typical of Lycoris.
The free-spirited, optimist and pacifist Chisato, and the cool, efficient Takina - a duo with completely opposite personalities - begin their crazy days.
