Death Note, Vol. 4 sees the complexity of the Kira investigation deepen following the introduction of the Second Kira, Misa Amane. As L grows closer to the truth, he takes the extreme measure of having both Light and Misa confined under constant surveillance in an attempt to prove their guilt. Light orchestrates a brilliant plan to temporarily relinquish his ownership of the Death Note, erasing his memory of being Kira, yet maintaining his control through contingency plans. This volume is a masterpiece of deception and plotting, as Light maneuvers himself and Misa through L's traps, demonstrating the sheer extent of his foresight and manipulative genius, even without the memories of the notebook.
