Anzu Murata, assuming a false name, sneaks into the Mitarai household under the guise of a housekeeper in search of the truth behind the fire 13 years ago-a fire for which her mother was labeled the criminal behind its outbreak. Operating independently, Anzu's younger sister, Yuzu, reunites with their estranged father and presses him for information, but Makiko finds out about their clandestine meetings. Anzu takes action to keep their father quiet about their plans and becomes Makiko's manager, narrowly snatching the two sisters from the brink of disaster. While feigning disinterest in the Mitarai house, Yuzu secretly continues the search for the truth by looking into Makiko's fans from 13 years past!
