Intro. Riki is a 27-year-old agent and serial killer. Everyone, including the police and female detective Ruka, was looking for Riki, but Riki was doing his job so carefully that he did not leave any traces behind. Riki had to go to Russia for a mission. As soon as Ruka finds out about this, she buys her ticket to Russia. Ruka, on the other hand, accidentally buys a ticket to Russia to visit her mother. Ruka and Riki unknowingly board the same plane. While Ruka was sitting on the plane and searching for Riki on the phone, Riki was standing right behind Ruka with his black mask and hat. Riki was determined to kill Ruka, but he sat in the seat next to her so that no one would suspect. As the journey continues, Ruka hears a noise from the trunk and the smell of a corpse. When Ruka saw Riki in the black mask, she knew that Riki was here too
