Its not on there anymore I don't think. But,when it was on it aired Saturday nights.
Its an awesome story.
A high school student finds a notebook that belongs to a God of Death. Whatever name is written in the book has a heart attack instantly.
The student starts writting the names of criminals in the book to make the world a better place. He kills millions with the book. All the while the death god pokes fun at him, he's very sarcastic,not evil at all.
Well law enforcement is pissed all over the world because the student is stealing their thunder. This mean EVERYONE in the world is looking for him. It turns out that the lead investagator is the students own dad and they live in the same house.
There are quite a few other complications in the series...another notebook shows up and another highly skilled detective gets after him.
Its really fast moving.
I really like the Demon God, he's funny as hell from what I remember.
Its on Hulu,I believe.
