This story will revolve around a global secret society of monster hunters called the Paranormal Defense Recon or P.D.R. who deals with paranormal creatures and threats of all kinds whether it be earthly, supernatural or extraterrestrial. It will have some elements from Parasyte and Elfen Lied as well as having monsters from actual mythology and folklore. Monsters will be classified in different categories, bizarre creatures created by nature will be classified as cryptids, supernatural creatures will be classified as unnaturals, genetic mutants will be called deviants, artificially created beings will be called synthetics and extraterrestrial beings will be classified as exos.
Just for starters I will classify the species from Elfen Lied and Parasyte:
Kiseijuu(classification:unknown)-a shape-shifting parasitic species of unknown origin with similar behavioral trait to the tongue-eating louse in that it eats and replaces entire body parts preferably the brain, in it's larval state it resembles a worm and once matured it replaces the body part it resides in.
Diclonius(classification:deviant)-a species of genetic mutant created through a retro-virus of unknown origin with hereditary effects. Effected offspring will have pink hair, horns and red eyes, as well as being inherently aggressive towards humans, using telekinesis in the form of invisible hands to kill or infect. Patient zero was an unknown woman in Kanagawa Prefecture in japan who abandoned her effected child in Kamakura, said child would later be named Lucy.
