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!?

Chisato reluctantly went to DA Headquarters for a health checkup and physical fitness test. When Takina heard, she decided to tag along to make a direct request for reinstatement at DA. With Chisato, Takina negotiates, but their commander will hear none of it. Moreover, her ex-partner Fuki is teaming up with a new companion.

Chisato breaks the news that she will shut down Café LycoReco so that Mizuki and Kurumi do not get caught up in her personal affairs. Around the same time, Takina, who returned to DA, uses Majima as a stepping-stone to track down Yoshimatsu in order to save Chisato's life. They finally captures Majima's client and infiltrates their hideout…!?

All is settled with the incident at Enkuboku—or so it seems until Majima, who should have been defeated at the old Radio Tower, reappears before Chisato. Majima planted a bomb in the Enkuboku, betting on the explosion when he challenges Chisato to a one-on-one fight. As Chisato's own time limit approaches, the final battle begins!
