After learning that Café LycoReco is in the red, Takina decides to take charge of accounting on her own. Takina flawlessly breaks down everything from indiscriminately restraining Chisato from wasting bullets to shadowing the café's members. She even goes as far as planning a new menu item. But the menu item has a shape that’s too terrible to put into words!?

Chisato's artificial heart was targeted. Now that the battery can no longer be charged, the remainder of Chisato's days are set. Kurumi, who chases down clues about the irreplaceable artificial heart, asks Mika about what happened back then. Meanwhile, Chisato is summoned to Headquarters as DA prepares for a large-scale operation to suppress Majima.
