You are Naoto Jinguji, a talented FBRP researcher with a focus on supernatural beings. You are tasked to study the first live succubus in captivity. As the planes begin to overlap with increasing frequency, the bureau's board of directors is getting anxious and begin pressing you for results, causing you displeasure from the board's ironfisted policies. Faced with a growing amount of sympathy for the succubus, you will have to make choices that may affect your life.(Storyline via IGDB)
