“I've got about 5 minutes before that woman gets to the police headquarters. Think. I need her real name. And I don't have much time to spare. If this woman makes it to the police station and someone from the task force has returned by then, it'll all be over for me. I've gotta find out her real name and eliminate her quickly.”
Overcast (曇天, Donten) is the seventh episode of the Death Note anime.
Light writes "Shoko Maki" in the Death Note, the cause of death being: "Thinks of the best way to commit suicide that won't bother others and will make it so her body isn't discovered. Thinks of nothing but suicide, carries out her plan, and dies within 48 hours."
At first, Light is confused to see that the woman is unaffected, but after recalling Ryuk's laughter when she gave her name, he quickly realizes that Penber's fiancée is using an alias.
Light begins to fear the worst; she may lead the police to him. Ryuk uses this opportunity to once again pressure Light into getting the Shinigami Eyes.
Becoming increasingly desperate he coaxes information out of the woman discreetly, pretending to work for L, and promising her that her information will be passed onto him.
In the time that has passed, L reveals his identity in the meeting with Light's father and the other detectives. He also gives the detectives special gadgets embedded in clothing in the event Kira comes into contact with them or if they are in trouble.
Light stops her from going to the HQ by saying the Kira Investigators are impossible to trace in order to avoid a disaster. She reveals that she once worked for L and hopes to talk to him.
Light invites her to join L's investigation, all he needs is her name; she gives him her driving license. Naomi Misora finally reveals her true name and identity to Light, just as Aizawa, who had been heading to HQ, walks by without noticing the two.
As the Death Note takes effect, he informs her that he is Kira. Naomi subsequently departs to fulfill the conditions written in the Death Note, pleased with himself, Light walks in the opposite direction.
