Judgment

 Judgment is the 3rd chapter of Volume four and 28th chapter overall.

Plot
At Misa’s apartment, Rem discuses with her about another shinigami rule:

''A human with the shinigami eyes cannot see the remaining lifespan of other Death Note owners, including him/herself. '' Rem also tells her that a shinigami is not allowed to tell Death Note owners how much life they have left.

Back at the headquarters, L and Light are discussing the second Kira’s diary. Light decides not to tell L about the “notebook” entry while the investigation team zeroes in on the “30th” entry. They decide to broadcast the diary on television and cancel the Giants game at the Tokyo Dome that day so that the police can investigate. However, L realizes that the second Kira may not be that stupid, and he might have hidden other messages for Kira in the diary. Among them, L points to the entry where second Kira mentions a notebook in each of the locations mentioned in the diary, including Aoyama. He wants cameras installed in the streets of Aoyama, and police officers dressed as citizens looking out for any suspicious behavior. Light volunteers to go to Aoyama. L wonders that if Light was Kira, he volunteered in order to find the second Kira before the police.

Also, L orders his investigation team to strengthen security and destroy all photos of themselves, in case Kira and the second Kira ever do join forces. If Kira realizes that the second Kira has the ability to kill people just by looking at them, the real Kira might gain this power.

Matsuda, who is accompanying Light to Aoyama, gets a call from L who orders him to secretly keep an eye on Light.

When Light arrives home, Light asks Ryuk if shinigami are allowed to interact with each other in the human world. Ryuk answers that there’s no rule against it, but personally, he feels like shinigami shouldn’t tell humans about other Death Note owners.

It’s May 22nd, and Matsuda hanging out with Light who is talking to a group of his friends in Aoyama. Light passes by a restaurant where Misa is sitting in disguise. With her shinigami eyes, she sees Light’s name, but no lifespan. She has finally found Kira. However, she decides to go home and do research.
