Ok, where did light go after death? Not clouds vill, not the great fire pit. The only other world they talk about is that of the shinigami. ONLY shinigami have been shown there. It would make sense that those people that use a death note or the first person to pick it up become shinigami after they die.
There are MANY hints to this even though I am sure it was not ment to seem that way.
Also a shinigami's life span is = to the remaining years he took from someone, so when ever a shinigami comes into being it should have 0 years to it's credit right? Not if he got years from being in the human world and it carries over to the shinigami after life! It is the only way I can think of that would make sense as to why shinigami do not die the second they become a shinigami. ( Unless there is something unknown i can not account for. )
Hey dont blame me if you click on a thread to an anime and they talk about a spoiler. I would think the name would be enough to stop you from clicking noobs.
