Creation

 Creation (創造, Sõzõ) is the third chapter of Volume seven and 55th chapter overall.

Plot
Back at the headquarters, the team wonders how Higuchi could have suddenly died. They ask Rem, whom they can all see now, and she reveals nothing in order to protect Misa. Aizawa reads the rules of the Death Note. He turns to the back of the book and read two additional rules:

"If the person using the note fails to consecutively write names of people to be killed within 13 days of each other, then the user will die."

"If you make this note unusable by tearing it up or burning it, all the humans who have touched the note will die."

Rem realizes that Light made Ryuk write two fake rules down in the Death Note in exchange for an apple.

However, the team now concludes that Light and Misa cannot be Kira and the second Kira because they were detained for more than 13 days without writing a name down in the notebook, and they didn’t die. L, sadly, agrees. Unable to destroy it, the team decides to lock the notebook up where no one can find it. L asks Rem if there are other notebooks and if the same rules apply to all of them. Rem says they do and doesn’t tell L that the two rules are fake, in order to protect Misa.

Even though he still suspects Light, L agrees to remove the handcuffs from him However, Light volunteers to keep helping the Kira investigation. Afterwards, L questions Rem that if the “eyes” that the second Kira mentioned were the eyes that allow a human to see a person’s name when they see their face. Rem does not deny it, but tells L that he can only tell the details of the “eye trade” to the owner of the Death Note. L realizes that if Misa was indeed the second Kira, she probably saw his name that day when they met at To-Oh University. However, Misa seems to have lost her memories, and the fake rule said that if an owner doesn’t use the notebook after 13 days, they die.

Misa has been freed and says good-bye to Light who is staying with the investigation. When Misa hugs him, Light whispers in her ear that she should dig up something at the location that he tells her.

Conception
Ohba said the chapter's title "Creation" simply refers to a part of the speech from Light when he states "The god of the world creates the rules."
