Supernatural phenomena and strange occurrences are no sweat for the Nanami Paranormal Investigation agency, headed by Asagi Nanami. As "freak" activity grows to a terrifying fever pitch, Asagi's assistants—Naoki, Tokiko, and Mahime—help to solve several major "freak" cases. Freaks are creatures with the ability to possess humans and prey on their weaknesses. However, Asagi and his gang are no ordinary humans; each is equipped with a special power to vanquish Freaks. Wacky paranormal adventures await! (Source: DrMaster)
