Tooru lost his memories and roamed the street of Yokohama searching for his identity and past. There were many contacts on his cell phone and his room was full of weapons and fake passports. Men in black suits chased after him and his body instinctively knew how to fight. It was obvious that he was not a normal person before losing his memories. He also had a room key in his pocket and when he found the hotel and entered the room, he was appalled to find a murdered woman with the word ‘Pigrizia’ written on the wall in blood. This was part of the ‘Seven Deadly Sins’ murders that the public had been abuzz about. Finding a memo on his cell phone that looked like a murder plan, he began to suspect whether he was the serial killer. Then he met a man that looked like the spitting image of himself.
