Tradeshows and Psychos! Dr. Ogami's new patient is accused of being a serial killer, and his blood holds far more secrets than just the truth. Meanwhile, Dr. Ogami's old rival wants nothing more than to destroy Dr. Ogami's Power Suit Prototype II at the hi-tech weapons exhibition, but our lovely nurse, Nanako, is inside! The patient and the rival both pursue Nanako for more than her good looks, and if she's not careful she won't be able to bounce back from their advances!
