When a magic notebook that kills who has a name written on it falls in the hand of a student that uses it to kill criminals, the law enforcement must find a way to stop him.

When a student starts killing criminals by recording their names in a supernatural notebook, "L"--a nameless detective must prevent him before he becomes unstoppable

I think basically the author play with our morals... in Breaking Bad, we definitely root for Walt, maybe until the point we think "well.. perhaps he have gone too far..." when he confess to Skyler his real reason.

In Death Note at first we might root to Raito, the student who finds the notebook and decide to kill criminals.. but at then I think it depends on where the audience stand about "vigilantes". If I. Kant would read the comics he would definitely root for "L" since the beginning hahah.?? But yes, personally I'd put Raito for protagonist and L (and police) as antagonist. It looks like the author twists that at some point in the story as if he is making a point regarding making justice with his own hands.

Now thinking about it, I don't remember that Raito even has a personal reason to use the notebook, (like Batman who had his parents killed, etc...)

>>>the character ?L?, a super detective that rivals Raito's (protagonist) intellect should be in place of the ?law enforceme

I'm confused.? Who is the character the audience is supposed to root for to solve the case?? Whoever that is, should be the designated protagonist.? (He doesn't have to be the smartest, or the strongest.? The audience could be rooting for an underdog.)? And in a logline, fictional characters (as a rule) are not identified by name.? Rather they are described by a character flaw or defining characteristic.
