This episode is curious. It's more of a series of events that further bind Michiru to Chika and Shito as their assistant (or as they call her, slave), and it also introduces several colorful characters who join the cast of this series. We were already flirting with the yuri genre in the last episode, but now we literally have a lesbian character who is a sexual harasser. This chapter serves to establish and explain a bit about the dynamics of the zombie loan agency, and the next case to be solved only has a couple of scenes, albeit visually interesting ones. Like the way Yomi channels the clues to reach the next enemy. I'd say it's almost a transitional episode.
