Plot
Misa asks Light if she could see his shinigami. Light makes her touch a piece of his Death Note, and Misa meets Ryuk.

All night, L has been going over the security camera tapes from Aoyama. He tells the team that Light is now the prime suspect in this case, and he is checking to see if they catch Light or the second Kira acting suspicious. Misa tells Light the rule about shinigami being killed because they fell in love with a human. Misa then explains the extent of the power of her shinigami eyes. Then, Light asks her send a final tape to Sakura TV as the second Kira saying that she has decided not to meet the real Kira but will help Kira’s cause by killing the criminals that Kira hasn’t killed yet.

He tells Misa that if she’s ever caught, she should never mention anything about the notebooks and the shinigami to the police. He explains that Light is already under heavy suspicion over being Kira and can’t really risk bringing Misa over to where L is. Light explains to her that he must go on dates with other girls in order to curtail more suspicion. Misa, who has proclaimed that she has fallen in love with Light, refuses to go along with it. Light threatens to kill her if she doesn’t obey, but Rem counters by saying that if he kills Misa, Rem will kill Light.
