Mika received a text. Chisato happened to peek at that text and makes a huge fuss when she suspects that Kusunoki is trying to bring her back to DA! To prevent their plans, the four members of LycoReco join forces to rush the bar where Mika has a secret rendezvous!

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.
