Takina Inoue, a secret agent who protects the security of Japan called a "Lycoris," is ordered to transfer to the café LycoReco in consequence of a certain incident. Takina is enthusiastic about returning to DA now that she's buddied up with the super-elite No. 1 Lycoris (?) Chisato, but her job at LycoReco is just one weird thing after another!?

The client this time is Matsushita, a man whose body is connected to a machine. Knowing his time is short, Matsushita returns to his homeland of Japan for some sightseeing. Chisato and Takina, who were requested as bodyguards and guides, go all out to support Matsushita's Tokyo sightseeing tour! Meanwhile, Takina learns a curious fact about Chisato!?
