Slapped to death by breasts XD
Nah, just kidding. I'd either want to die saving someone I love, or die as I finish the last sentence of a book.
"Now, I think it's time to put down my pen. But...what should I call the sequel?"
I actually really want to die like Jiraiya, sacrificing myself to pass on vital information. That would be a fitting end for someone like me.
Or, alternatively, I personally wouldn't mind being gunned down by Santa Claus.
