Grand Unifying Guesses/Death Note

Possible Kiras:
But in Zetsubou Billy, the lead singer of Maximum the Hormone stated that he and his band are Kiras, and so are we ("Even you're Kira!"), so what does that mean?
 * It means that they were lying.

The implications of this are disturbing...
Teen Girl Squad is what happens when somebody draws a comic in a Death Note - that girl who wrote the email SPECIFICALLY TOLD STRONG BAD ALL HER FRIENDS' NAMES. You notice she never wrote back to him.
 * Doesn't this make Strong Bad a Kira then?
 * Note: Only Kristen's name was written in the comic. Therefore, she is probably dead. The rest of them are fine. Also note that Strong Bad did not use his real name. At least, I don't think so...* eerie music?*
 * But you have to know what someone looks like to use a Death Note.

Death Note takes place in the same universe as Dead Like Me
There is a person mentally contected to each book who receives the names of people about to die. They in turn pass the names onto the leader of a reaper group, and this is how they know who is going to die.

Death Note takes place in the same universe as Mirrormask
There is a reason that everyone in that world wears a mask, are afraid to show their faces, and say as little of their name as they possibly can. Also, see the fanfiction "The Faceless" which has people wearing masks 24/7.

Lorien is the Shinigami King.
Lorien is an immortal being that knows and can tell humans their remaining lifespan. It makes sense that he's the Shinigami King since the King makes the rules and if he so wishes can circumvent the rules of death.
