Happy Ending

Heh.

At the end of the Big Fight between the Hero, the Villain, and whoever else happens to be there, the Hero draws their weapon one last time, utters a Badass Line (optional), and finally puts an end to the Villain. Some time later, the Hero returns home and meets the townspeople who somehow got notified about the Villain's fall (maybe The World Is Healing is a sign that Evil Is Dead).

Happy Ending is a kind of Story Ending that can only be achieved if the Good Guys do at least most of what they have to on their journey through the story. Should they fail to complete the to-do list, they'll instead meet an Unhappy Ending and fail the world that that were meant to protect.
