Although there are abundance of evidence shows that the seven Yotsuba members are connected to the newest Kira but which member who actually possesses the Death Note are unknown to the taskforce.
In this volume, Light, L and the rest of the taskforce are trying to discover who is the newest Kira. In desperation, L asks Misa for help to get more information from the Yotsuba members. In an unexpected circumstance, Shinigami Rem reveals to Misa about her past and who is the Kira among the seven Yotsuba members. With all the given knowledge, Misa will do anything to help Light by putting herself in the risk. Misa finds out who is the newest Kira and with the help of Light and L, they set up a trap to capture the newest Kira.
Compexity goes to another level. It's getting closer to the truth. It was so intense when they almost find out how Kira kills people. Although they have no idea how it works but it was really close. So close.....
