With demonic possession on the rise, you can count on Dr. Taima to needle it out! Dr. Taima possesses an arcane ability to adeptly wield the taimashin, needles used to banish malefic and parasitic spirits. Together with his assistant, the lovely Maki Togetsu, Dr. Taima investigates the outbreak of demonic possessions around town that have turned ordinary and unassuming citizens into ravenous monsters that devour anything within their grasp - dogs, cats...even other people! Taima's investigation leads him to Dunwich, Massachusetts, where he meets another needle wielder, Kyogo Ayakashi. As they encounter ancient evils that are best kept secret, how will these taimashin masters bait their prey?
