Your job is to interrogate Rena and get her to tell you the truth. Are you going to be a good cop or bad cop? Are you going to get her to talk nicely or have to rough her up a bit? You have at your disposal the dialog option, where you can ask her questions. And you have at your disposal various sex and interrogation devices. Some can’t be used right away, some require Rena in a certain position or without some of her clothes on. Click on part of Rena, the interrogation tools and the dialog icon to proceed and advance in the game. There are different endings based on how you get her to confess.
