1

After a female assassin named Laura kills Rin on a rooftop, she wakes up unharmed in her apartment. She searches for a missing cat and encounters Kouki Maeno, who feels his memories are fabricated despite not being amnesiac. Rin and her partner Mimi discover Kouki is linked to Aoyama Pharmaceutical. They infiltrate the company's labs but are captured. The chief researcher, Sayara Yamanobe, tortures Rin to death, while Kouki is revealed to be a runaway cloning test subject. Rin miraculously survives her injuries and confronts Yamanobe, leaving her to delirious test subjects. As the facility is demolished, Rin gives Kouki a gun to decide his fate. He appears to commit suicide, but the next day he returns to her office with the cat and a head wound, asking to become her business partner.
