Candy Of Shinohara: about death note

Yagami Light is a brilliant college student who, one day, finds a
notebook simply titled "Death Note." Inside of this book is a list
of rules and details as for the use of the "Death Note." When he
realizes the power he holds, he decides he's going to make over the world.
He wants to make it into a better place by killing those who do others harm.
He has been nicknamed by the police "Kira." L, a brilliant detective who lives in secrecy,
rises from the shadows and puts his life on the line trying to capture Light.
Both L and Light believe themselves on the side of Justice, and the two
match wits trying to show exactly which of them is "good" and which of them is "evil."

Light Yagami, he had just perpetrated the most elaborate and successful demonstration of his Death Note, the supernatural notebook that kills anyone whose name is written inside it. As a result of his clever scheming, Light was invited to join the investigation team chasing the mass murderer known as Kira -- who just so happens to be Light, anonymously using the Death Note to kill scores of criminals daily. However, oddball super detective and avid sugar-lover L truly suspects that Light is Kira, and he's not shy about letting Light know. During their initial and subsequent meetings, L basically rubs Light's face in his obvious suspicion.
However, instead of avoiding potential capture, Light embraces the chance to work side-by-side with his sweets-loving rival. Now that L and Light/Kira are working together, the stage is set for an epic battle between two insanely smart guys who like to talk a lot. It's a showdown of acrobatic mental geniuses, who use keen reasoning and elaborate mindgames to outwit their wily opponent. Who will be the last name written in the Death Note? Will it be the megalomaniacal Light, or the wacky but honorable L? And will Death Note fans pissed at the fate of the manga characters find this new cinema version to be satisfying?

Ken'ichi Matsuyama reprises his role as L Lawliet from the previous Death Note films. The film chronicles the final 23 days of L's life, as he solves one final case involving a bioterrorist group that aims to wipe out much of humanity with a virus with ten times the infectiousness of Ebola, taking a boy, the sole survivor of its use in a village in Thailand, and a junior high schooler named Maki Nikaido under his wing. Shunji Fujimura also reprises his role as Watari, though he dies early in the film as per the events of The Last Name. The characters Misa Amane, death god Ryuk, and Light Yagami also all have brief cameos in the film.
