Zabuza Momochi, also known as the Demon of the Hidden Mist. After his final climactic battle with Team 7 on the bridge, Zabuza expected to spend the rest of eternity being tortured in hell. Instead, he is sent to a land of candy colored talking horses, a distinct lack of mercenary jobs, and to top it all off, the Princess expects him to start sending friendship reports to her every week!

On second thought...maybe this is hell.
