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!?

The Lycoris of DA stormed the Enkuboku to stop Majima. Just before the operation, Takina rushes to Café LycoReco when Kusunoki informs her that they cannot get in contact with Chisato. However, after receiving threats from Robota, Chisato and Mika set out to rescue Yoshimatsu, who is being held hostage...

Chisato is dragged into a tough fight against Majima at the old radio tower, but Takina rushes in just in the nick of time. Meanwhile, the existence of the Lycoris is exposed to the public due to Majima's ploy. At Headquarters, Kusunoki's command is stripped, and a decision is made to dispose of the Lycoris inside the Enkuboku!?
