Light Yagami is an excellent high school student - who, however, is desperately bored. Everything changes when he finds the Death Note, a "death notebook". If someone's name is written on the pages of this notebook, that person will die. So, Light has set a goal to use the powers of the notebook to rid the world of evil. With the world's investigative services under the guidance of the brilliant L on his trail, will Light be able to stay focused on his goal?

Light, L, and the rest of the task force have gathered enough evidence to prove the involvement of the seven members of the Yotsuba Group in the Kira case. Despite all the clues they have, however, they cannot determine the owner of the Death Note. So, L decides to seek the help of Misa, whom he will use to force Kira to make a mistake. The involvement of Rem, the god of death who has bound her fate with Misa, is a factor that even L himself cannot calculate...
