Episode 1: Cats Don't Laugh

The episode opens with Rin being chased to the rooftop by a female assassin named Laura. Severely wounded, Rin falls down to her death. In the next scene, she wakes up unscathed in her apartment and returns to work, looking for a stray cat she was hired to find. Circumstances lead her to run into a man named Kōki Maeno in a quiet street. After knocking out several agents pursuing Kōki, Rin takes him to her office where he tells her and her partner Mimi that although he is not amnesiac, he feels that his memory is fake and he would like to know why he is pursued. Through Rin's links, they find out that Kōki is connected to the Aoyama Pharmaceutical company. With Mimi's help, they infiltrate its labs but are captured. Rin is tortured to death by the sadistic chief researcher Sayara Yamanobe, while Kōki is revealed to be a runaway cloning test subject. Miraculously, Rin survives, completely healed of her injuries, and confronts Yamanobe, leaving her in the hands of other delirious test subjects. As the compromised facility is demolished by Aoyama Pharmaceutical, Rin escapes with Kōki and hands him a gun, for him to decide what he wants to do with his life. After he seemingly commits suicide, Rin leaves the scene. The next day he appears in her office, wounded on the head and with the missing cat in his hands, and asks to become her business partner.
