Death Note: Desu nôto2006

Light Yagami:
If the cause of death is written within forty seconds of writing the person's name, it will happen. If the cause of death is not specified, the person will simply die of a heart attack. After writing the cause of death, details of the death should be written in the next six minutes and forty seconds. That sound right to you, Ryuk?

Ryuk:
So what's your point?

Light Yagami:
In other words, if I write "heart attack is the cause of death," then I should be able to write down all the details, including time of death afterword, shouldn't I? Looks like I'll be able to provide you with more entertainment, now.
