I AM L

Lawliet had been living his whole life in isolation until a faithful day occurred. His parents told them that they have to leave him and someone will look after him for awhile. But they give no reason to why they have to leave him. When tragedy happens in the family, a man named Watari takes the young boy in. Lawliet doesn't trust him at first and is skeptical of his generosity but in his rage, he figures out that he has something important to do which will leeds him to what Lawliet calls, Case 0.
LLLLLLLLLLLLLLLLLLL
Note that I haven't watched any of the Death Note movies like 'L Change the World' or anything so there probably won't be any references to that. :( Also there will be some fan characters just to let you know.
