Imprisonment

 Imprisonment is the 9th chapter of Volume four and 34th chapter overall.

Plot
In a deserted forest, Light tells Rem that he relinquishes the ownership of Misa’s Death Note. He has buried the Death Note in the forest and gives Ryuk specific instructions. The second that Light says “Get rid of it” to Ryuk, Light will give up ownership of his Death Note.

Misa has once again awakened. However, she is continually referring to a stalker and asking to be let go. This puzzles the investigation team. She tells them that she assumes that she is being held hostage by a crazed stalker. It is as if she has no idea about the Kira investigation. When asked about Light, Misa acknowledges that he is her boyfriend when she had refused to do so earlier.

Then, Light enters the investigation headquarters claiming that he thinks he might be Kira. L is now convinced that Light is indeed Kira, and he is wondering what exactly he is planning. Soichiro is begging his son not to say such things, but Light answers that all of the evidence points to him, and even though he might have no consciousness of it, there’s a chance that he might be Kira. He fears that he’s losing his mind. L wonders if this is all part of Light’s plan. However, he orders that Light be restrained to the dismay of Soichiro.
