What happens

Ruby stops playing the cheerful junior and uses a web variety show, and the missing agency founder, to climb. Aqua has to admit the closed case was never closed: the name on a family register and the man who fathered them are not the same person. Akane reaches that name first and tries to finish it without him; he cuts her out so she cannot.
