Psychic Supernatural Boyfriend is a game about love and friendships between a human girl, her boyfriend, and two demons. You have just graduated from the detective academy and are prepared for your first task. You and an experienced detective are given the duty of locating your first demon because of your keen sense of the paranormal.

Unfortunately, the work is anything but simple, and you quickly come to the realization that you've stumbled upon something much more significant than anyone could have anticipated. Massive amounts of energy may be detected by your senses, but it appears that the demons can find you just as quickly.
