Why does love kill Shinigami in Death Note? Well, that's what I'll be talking about in today's blog post! There may be a few spoilers in this post though, so proceed with caution! Now then, on with the post! Although it is stated that a Shinigami dies by killing someone else in order to protect a human they love, it's never really explained why this is. So, why does love kill a Shinigami? First of all, it's not really the love that kills a Shinigami. Instead, it's the act of prolonging a human's life that was supposed to end. Because of this, I believe a Shinigami dies because the human needs a new lifespan after theirs runs out. So to balance this out, the Shinigami's lifespan will be added onto the human's life, causing the Shinigami to perish. This is also why this is the only known way to kill a Shinigami, since the Shinigami will keep their lifespan in any other deadly situation. So in sacrificing themself, whether intentionally or not, the Shinigami is actually just transferring their remaining lifespan to the human who's lifespan had run out. This is shown when Rem is explaining the way of killing a Shinigami to Misa, since she says that Misa's life was extended long past even a normal human's lifespan. But, these are mostly just my thoughts on this topic anyways. Nonetheless, I hope you guys still enjoyed this blog post! As a little bonus, I will be including a picture of Misa below. Enjoy!
