Eight

Eight (八, Hachi) is the 3rd chapter of Volume five and 37th chapter overall.

Plot
L chains himself to Light using handcuffs so that he is never far from his sight. L then asks Misa why she went to meet Light in Aoyama and how she learnt Light’s name without speaking to him. Misa answers that she doesn’t know. Then, L asks her how she would feel if Light was Kira. Misa answers that she would be happy because she respects Kira after he killed her parent’s murderers. However, Misa still denies that she is the Second Kira. Still, L wants to keep Misa under surveillance so he has set up a room for her full of cameras and has set up Matsuda as her “manager.”

Then, L asks Light if he could use Misa to find out any information she knows about Kira. Light answers that he refuses to play with a woman’s emotions like that. A stunned L wonders if Light suddenly got a personality change.

L shows the investigation team the new headquarters that he has set up for them. Light vows that he will help L catch Kira no matter what.

Meanwhile, eight representatives from the Yotsuba company are meeting in a board room and talk about who they are going to kill today. They acknowledge that Kira was one of the eight members and that he is making them decide who they will kill that will be most beneficial to their company.

Conception
The chapter's title "Eight" refers to the eight Yotsuba members. Ohba had said that he worked quite hard to try to find a good chapter title since "Eight" had been printed with color pages in the Weekly Shonen Jump.
