Reversal

 Reversal is the 1st chapter of Volume four and 26th chapter overall.

Plot
At the investigation headquarters, L elaborates on his plan further. He doesn’t want to reveal to Light the possibility that this might be a fake Kira because he wants to test him. Light is very clever and if he was truly Kira, L deduces that he would not reveal the existence of a second Kira until after L is dead. However, if he does point out that this might be the work of a fake Kira, Light will be mostly cleared from suspicion. Light goes to the Kira investigation headquarters, and L shows Light the evidence gathered from the tapes. Light watches the tape and decides to let things take their course by not revealing that this may be a second Kira. However, Light quickly realizes that this was a trap set up by L. He tells L that this may have been the work of a second Kira with even greater powers by the first. As Soichiro breathes a sigh of relief, L tells Light that they were thinking exactly the same thing and that he wants him to help with the investigation by playing the part of the real Kira. A stunned Light writes a message from the real Kira to the second Kira that they will broadcast on TV.

Misa is eagerly watching television at her apartment when the news station announces that they must broadcast a video tape from another person claiming that he is the real Kira. The “real Kira” says that even though he is pleased that there are people willing to help him with his goals, he wants the fake Kira to discontinue the killing of innocent people or else he’ll pass judgment on the imposter.

Misa sends Kira a response. The investigation task force watches it as soon as Sakura TV receives it. The second Kira proclaims that she will do as Kira pleases. Light is disappointed that the second Kira continue forcing L to show his face on TV. Then, the second Kira says that she wants to meet the real Kira and that she doesn’t think that he has “the eyes” and that they can show their shinigami to each other. L and the investigation team are puzzled by these terms. Light finds it stupid that the second Kira would reveal something like that on TV.
