In 1993, four dog lovers disappeared one after another in Saitama Prefecture, and two years later, a man and a woman who run a pet shop were arrested. Former convict on death row Gen Sekine and Hiroko Kazama were arrested. It is the "Saitama pet dog serial murder case" that shook Japan from the brutal technique of dismantling and abandoning the victim's body and destroying the evidence as "making the body transparent". The two arrested in this case were sentenced to death in 2009. However, the whole picture of the case, such as the discrepancy in testimony, remains unclear. It has been 25 years since the arrest, and this time, the case has been made into a drama based on interviews and testimonies to the people concerned. It depicts the whole picture of this case where many mysteries remain.
