Tomorrow

Tomorrow is the eighth chapter of volume ten and eighty-ninth chapter overall.

Plot
Light decides to seduce his ex-girlfriend in order to get her to trust him. Then, he’ll be free to use her however he wants. He plans to book a hotel room and invite her over.

Meanwhile, Mello notices that Mogi and Misa are at LAX waiting to catch an airplane to Japan. He calls Matt and tells him that they will follow them to Japan.

Aizawa reminds Light that he will be planting cameras and wires in the hotel room in order to keep an eye on him.

As they all watch Takada on the news, Light worries that Mikami may be taking things a bit too far when he kills people who commit crimes without evil intent and those who are lazy. However, this motivates him to start manipulating Takada now so that she can relay messages to Mikami.

Takada arrives at the hotel room after the nine o’clock news. Light starts off by telling her that he has missed her terribly. However, he gets down to business by pretending to admit that Kira was right in his goals, but that Takada should, as a journalist, question Kira’s ideals as well as spread them. After that, they sit quietly for a long time, and then Takada tells him that he has to go. Before she leaves, Light tells her that he wants to see her again.

Conception
Ohba said that the chapter title "Tomorrow" simply refers to the scene in the chapter's final page, when Light asks Takada if she can see him the following day. In his words it had no "deep meaning".
